BACKGROUND: We investigated a large, foodborne outbreak of hepatitis A that occurred in February and March 1997 in Michigan and then extended the investigation to determine whether it was related to sporadic cases reported in other states among persons who had consumed frozen strawberries, the food suspected of causing the outbreak. METHODS: The cases of hepatitis A were serologically confirmed. Epidemiologic studies were conducted in the two states with sufficient numbers of cases, Michigan and Maine. Hepatitis A virus RNA detected in clinical specimens was sequenced to determine the relatedness of the virus from outbreak-related cases and other cases. RESULTS: A total of 213 cases of hepatitis A were reported from 23 schools in Michigan and 29 cases from 13 schools in Maine, with the median rate of attack ranging from 0.2 to 14 percent. Hepatitis A was associated with the consumption of frozen strawberries in a case-control study (odds ratio for the disease, 8.3; 95 percent confidence interval, 2.1 to 33) and a cohort study (relative risk of infection, 7.5; 95 percent confidence interval, 1.1 to 53) in Michigan and in a case-control study in Maine (odds ratio for infection, 3.4; 95 percent confidence interval, 1.0 to 14). The genetic sequences of viruses from 126 patients in Michigan and Maine were identical to one another and to those from 5 patients in Wisconsin and 7 patients in Arizona, all of whom attended schools where frozen strawberries from the same processor had been served, and to those in 2 patients from Louisiana, both of whom had consumed commercially prepared products containing frozen strawberries from the same processor. CONCLUSIONS: We describe a large outbreak of hepatitis A in Michigan that was associated with the consumption of frozen strawberries. We found apparently sporadic cases in other states that could be linked to the same source by viral genetic analysis.  (+info)

Changing epidemiology of hepatitis A in the 1990s in Sydney, Australia. (2/837)

Surveillance of hepatitis A in residents of Eastern Sydney Health Area identified substantial epidemics in homosexual males in 1991-2 with a peak rate of 520 per 100,000 recorded in males aged 25-29 years, and again in 1995-6, with a peak rate of 405 per 100,000 per year in males aged 30-34 years. During 1994-5 an epidemic was detected among disadvantaged youth associated with injecting drug use; peak rates of 200 per 100,000 per year were reported in males aged 25-29 years and of 64 per 100,000 per year among females aged 20-24 years. The epidemiology of hepatitis A in these inner suburbs of Sydney is characterized by very few childhood cases and recurrent epidemics among homosexual men. Identified risk groups need to be targeted with appropriate messages regarding the importance of hygiene and vaccination in preventing hepatitis A. However, poor access to health services among disadvantaged youth and a constant influx of young homosexual males into these inner suburbs present major challenges to hepatitis A control.  (+info)

Prevalence of enteric hepatitis A and E viruses in the Mekong River delta region of Vietnam. (3/837)

A study of antibody prevalence for hepatitis A virus (HAV) and hepatitis E virus (HEV) was carried out in southwestern Vietnam in an area adjacent to a known focus of epidemic HEV transmission. The purpose of this investigation was first to provide a prevalence measure of hepatitis infections, and second to determine the outbreak potential of HEV as a function of the susceptible population. Blood specimens collected from 646 persons in randomly selected village hamlets were examined by an ELISA for anti-HEV IgG and anti-HAV IgG. The prevalences of anti-HEV IgG and anti-HAV IgG were 9% and 97%, respectively. There was a significant increase (P < 0.01) in age-specific anti-HEV IgG. A notable increase in anti-HAV IgG prevalence (P < 0.0001) occurred between child populations 0-4 (64%) and 5-9 (95%) years of age. No evidence of familial clustering of anti-HEV IgG-positive individuals was detected, and household crowding was not associated with the spread of HEV. Boiling of water was found to be of protective value against HEV transmission. A relatively low prevalence of anti-HEV indicates considerable HEV outbreak potential, against a background of 1) poor, water-related hygiene/sanitation, 2) dependence on a (likely human/animal waste)-contaminated Mekong riverine system, and 3) periodic river flooding.  (+info)

An outbreak of hepatitis A associated with an infected foodhandler. (4/837)

OBJECTIVE: The recommended criteria for public notification of a hepatitis A virus (HAV)-infected foodhandler include assessment of the foodhandler's hygiene and symptoms. In October 1994, a Kentucky health department received a report of a catering company foodhandler with hepatitis A. Patrons were not offered immune globulin because the foodhandler's hygiene was assessed to be good and he denied having diarrhea. During early November, 29 cases of hepatitis A were reported among people who had attended an event catered by this company. Two local health departments and the Centers for Disease Control and Prevention, in collaboration with two state health departments, undertook an investigation to determine the extent of the outbreak, to identify the foods and event characteristics associated with illness, and to investigate the apparent failure of the criteria for determining when immune globulin (IG) should be offered to exposed members of the public. METHODS: Cases were IgM anti-HAV-positive people with onset of symptoms during October or November who had eaten foods prepared by the catering company. To determine the outbreak's extent and factors associated with illness, the authors interviewed all case patients and the infected foodhandler and collected information on menus and other event characteristics. To investigate characteristics of events associated with transmission, the authors conducted a retrospective analysis comparing the risk of illness by selected event characteristics. To evaluate what foods were associated with illness, they conducted a retrospective cohort study of attendees of four events with high attack rates. RESULTS: A total of 91 cases were identified. At least one case was reported from 21 (51%) of the 41 catered events. The overall attack rate was 7% among the 1318 people who attended these events (range 0 to 75% per event). Attending an event at which there was no on-site sink (relative risk [RR] = 2.3, 95% confidence interval [CI] 1.4, 3.8) or no on-site kitchen (RR = 1.9, 95% Cl 1.1, 2.9) was associated with illness. For three events with high attack rates, eating at least one of several uncooked foods was associated with illness, with RRs ranging from 8 to undefined. CONCLUSION: A large hepatitis A outbreak resulted from an infected foodhandler with apparent good hygiene and no reported diarrhea who prepared many uncooked foods served at catered events. Assessing hygiene and symptoms s subjective, and may be difficult to accomplish. The effectiveness of the recommended criteria for determining when IG should be provided to exposed members of the public needs to be evaluated.  (+info)

Identifying target groups for a potential vaccination program during a hepatitis A communitywide outbreak. (5/837)

OBJECTIVES: This study sought to identify groups for targeted vaccination during a communitywide hepatitis A outbreak in 1996. METHODS: Residents of the Sioux City, Iowa, metropolitan area reported with hepatitis A between September 1995 and August 1996 were sampled and compared with population-based controls. RESULTS: In comparison with 51 controls, the 40 case patients were more likely to inject methamphetamine, to attend emergency rooms more often than other health care facilities, and to have a family member who used the Special Supplemental Nutrition Program for Women, Infants, and Children. CONCLUSIONS: Groups at increased risk of hepatitis A can be identified that might be [corrected] accessed for vaccination during communitywide outbreaks.  (+info)

The epidemiology of viral hepatitis in children in South Texas: increased prevalence of hepatitis A along the Texas-Mexico border. (6/837)

An initial retrospective study of 194 children demonstrated a high prevalence of hepatitis A but not hepatitis B or C infection among children living along the Texas-Mexico border. A larger prospective study of hepatitis A was conducted with 285 children (aged 6 months to 13 years) living in 3 sociodemographically dissimilar areas of South Texas. Children living in colonias along the border had a significantly higher prevalence of hepatitis A virus infection (37%) than children living in urban border communities (17%) or in a large metropolitan area (San Antonio [6%]). Independent risk factors for hepatitis A infection included increased age, colonia residence, and history of residence in a developing country. Use of bottled water (vs. municipal or spring/well water) and years of maternal secondary education were protective. Improved sanitation or routine hepatitis A vaccination in early childhood may reduce the prevalence of hepatitis A in these areas.  (+info)

Antigenic epitopes of the hepatitis A virus polyprotein. (7/837)

Forty-two antigenic domains were identified across the hepatitis A virus (HAV) polyprotein by using a set of 237 overlapping 20-mer synthetic peptides spanning the entire HAV polyprotein and a panel of serum samples from acutely HAV-infected patients. The term "antigenic domain" is used in this study to define a protein region spanned with consecutive overlapping immunoreactive peptides. Nineteen antigenic domains were found within the structural proteins, and 22 were found within the nonstructural proteins, with 1 domain spanning the junction of VP1 and P2A proteins. Five of these domains were considered immunodominant, as judged by both the breadth and the strength of their immunoreactivity. One domain is located within the VP2 protein at position 57-90 aa. A second domain, located at position 767-842 aa, contains the C-terminal part of the VP1 protein and the entire P2A protein. A third domain, located at position 1403-1456 aa, comprises the C-terminal part of the P2C protein and the N-terminal half of the P3A protein. The fourth domain, located at position 1500-1519 aa, includes almost the entire P3B, and the last domain, located at position 1719-1764 aa, contains the C-terminal region of the P3C protein and the N-terminal region of the P3D protein. It is interesting to note that four of the five most immunoreactive domains are derived from small HAV proteins and/or encompass protein cleavage sites separating different HAV proteins. The HAV-specific immunoreactivity of each antigenically reactive peptide was confirmed by using seven HAV seroconversion panels. Collectively, these data demonstrate that HAV structural and nonstructural proteins contain antigenic epitopes that can be efficiently modeled with short synthetic peptides.  (+info)

Ascertainment of secondary cases of hepatitis A--Kansas, 1996-1997. (8/837)

Each year, 25,000-30,000 cases of hepatitis A are reported in the United States. The most common infection source (22%-26%) is household or sexual contact with a person already infected with hepatitis A virus (HAV) (i.e., the source-patient). In Kansas during 1992-1997, contact with a source-patient was reported by 39% of persons with hepatitis A. Cases reported in 1996 and 1997 were studied retrospectively to determine the reasons for the apparently high proportion of secondary cases and to evaluate missed opportunities for prevention (i.e., postexposure prophylaxis with immune globulin [IG]). Results of this investigation indicate that persons with hepatitis A often were classified incorrectly as secondary cases and that some correctly identified secondary cases represented missed opportunities for prevention.  (+info)

Summary Infection of human embryo fibroblasts with hepatitis A virus (HAV), a picornavirus, leads to an inapparent, persistent infection; cultures can be passed serially with consistent recovery of the virus in the supernatant. All of the cells of a HAV carrier culture are infected and proliferate. Subcultivation under HAV-immune serum cannot achieve a cure or even a reduction in the number of infected cells in HAV carrier cultures. No interferon activity can be detected during HAV infection and persistence. Addition of exogenous interferon eliminates HAV infection in vitro. Persistence of HAV in vitro appears to contradict the clinical course of HAV infection in vivo. The system presented offers the possibility of evaluating the role of immunological injury of HAV-infected cells, an injury which may lead to damage of these cells and to elimination of HAV during an HAV infection in vivo.

People who inject drugs (PWID) are at risk for Hepatitis B virus (HBV) and Hepatitis C virus (HCV) infection through the sharing of needles and drug-preparation equipment. In addition, outbreaks of Hepatitis A infection have been reported among PWIDs; such outbreaks are believed to occur through both percutaneous and fecal-oral routes. The Advisory Committee on Immunization Practices recommends that PWIDs get vaccinated against Hepatitis A and Hepatitis B. Because of higher rates of infection among this population, CDC also recommends testing anyone who has injected drugs for HBV and HCV infection.. ...

Viral, or infectious hepatitis is a contagious, most dangerous disease in animals. Almost all species of both wild and domestic animals can be affected.
Schedule: Two doses of hepatitis A vaccine are recommended for all children beginning at age 12 months. The two doses should be separated by 6 months. Older children can receive it as well. If you didnt get the vaccine as a child, you should get vaccinated now if you are in a group at risk for hepatitis A, or just if you want to be protected. Hepatitis A is a vaccine-preventable, communicable disease of the liver caused by the hepatitis A virus (HAV). It is usually transmitted person-to-person through the fecal-oral route or consumption of contaminated food or water. Hepatitis A is a self-limited disease that does not result in chronic infection. Most adults with hepatitis A have symptoms, including fatigue, low appetite, stomach pain, nausea, and jaundice, that usually resolve within 2 months of infection; most children less than 6 years of age do not have symptoms or have an unrecognized infection. Antibodies produced in response to hepatitis A infection last for life and protect against ...
Hepatitis A (formerly known as infectious hepatitis) is an acute infectious disease of the liver caused by the hepatitis A virus (HAV),[1] which is most commonly transmitted by the fecal-oral route via contaminated food or drinking water. Every year, approximately 10 million people worldwide are infected with the virus.[2] The time between infection and the appearance of the symptoms, (the incubation period), is between two and six weeks and the average incubation period is 28 days.[3]. In developing countries, and in regions with poor hygiene standards, the incidence of infection with this virus is high[4] and the illness is usually contracted in early childhood. HAV has also been found in samples taken to study ocean water quality.[5] Hepatitis A infection causes no clinical signs and symptoms in over 90% of infected children and since the infection confers lifelong immunity, the disease is of no special significance to the indigenous population. In Europe, the United States and other ...
Hepatitis A is caused by a contagious virus, the hepatitis A virus (HAV) that infects the liver-it can lead to serious liver problems. The virus spreads through the feces of people who have the virus. If a person with the virus doesnt wash their hands after going to the bathroom, feces can get on their hands and can transfer to objects, food and drinks. When these things are shared, other people can unknowingly swallow the virus. If a person who has the virus comes in close contact or touches other people-this includes sex-the virus can also spread.. CDC says the following groups are at highest risk for acquiring HAV infection or developing serious complications from HAV infection in these outbreaks and should be offered the hepatitis A vaccine in order to prevent or control an outbreak:. ...
Humans, great apes, and some species of monkeys can be infected with hepatitis A virus. The primary source of hepatitis A for human transmission is person-to-person spread through the fecal-oral route. On rare occasions, hepatitis A infection has been transmitted by transfusion of blood or blood products collected from donors during the viremic phase of infection.15,16 Since 2002, nucleic acid amplification tests, such as the polymerase chain reaction (PCR) assay, have been applied to the screening of source plasma used for the manufacture of plasma-derived products.17. Transmission generally is limited to close contacts, and hepatitis A rarely is spread by casual interactions. Spread of hepatitis A within families is common, with disease occurring more commonly in older family members after being introduced into the household by an asymptomatically infected young child.12 In child care center outbreaks, contact with feces and subsequent personal contact are important means by which transmission ...
Hepatitis A virus (HAV) is primarily transmitted fecal-orally after close contact with an infected person (1); it is the most common cause of viral hepatitis worldwide, typically causing acute and self-limited symptoms, although rarely liver failure and death can occur (1). Rates of hepatitis A had declined by approximately 95% during 1996-2011; however, during 2016-2018, CDC received approximately 15,000 reports of HAV infections from U.S. states and territories, indicating a recent increase in transmission (2,3). Since 2017, the vast majority of these reports were related to multiple outbreaks of infections among persons reporting drug use or homelessness (4). In addition, increases of HAV infections have also occurred among men who have sex with men (MSM) and, to a much lesser degree, in association with consumption of imported HAV-contaminated food (5,6). Overall, reports of hepatitis A cases increased 294% during 2016-2018 compared with 2013-2015. During 2016-2018, CDC tested 4,282 ...
The Hepatitis A virus is the most common cause of Hepatitis in the world, and commonly occurs in young adults. It is spread from person to person by the fecal-oral route: that is, coming in contact with contaminated food, water, hands toilets, dishes, etc., of the infected person and eventually ingesting the fecal contaminant. Therefore, people sharing food, kitchen, or bathroom facilities with someone who has Hepatitis A can get infected. Hepatitis A is common in developing countries.. ...

Description of illness: Hepatitis A is a vaccine-preventable, acute, self-limited illness characterized by fever, malaise, jaundice, anorexia, and nausea. It is transmitted person-to-person through the fecal-oral route or through exposure to contaminated food or water. Only 30% of infected children younger than 6 years of age will become symptomatic, and few will have jaundice. Among older children and adults, infection usually is symptomatic and typically lasts several weeks, with jaundice occurring in ≥70%. Ten to fifteen percent of symptomatic people have prolonged or relapsing disease lasting as long as 6 months. Fulminant hepatitis and death is rare and is more common in people with underlying liver disease. Chronic infection does not occur. Serologic testing for HAV IgM in the absence of acute illness compatible with hepatitis A is not recommended due to the possibility false positive results, especially in older adults.. ...

Breastmilk is the ideal in infant nutrition, and breastfeeding the optimal delivery system. The American Academy of Pediatrics recommends exclusive breastfeeding for the first six months of life and continued breastfeeding with the addition of appropriate complementary foods for at least one year, and thereafter for as long as mother and baby desire.. The benefits of breastfeeding in terms of nutrition, increased resistance to diseases, allergy protection and psychosocial development, make it the most important, cost effective substance we have in medicine today. Unfortunately, breastfeeding has been implicated as a possible mode of transmission of various forms of hepatitis from mothers to their infants. Acute viral hepatitis is a frequent cause of liver disease in the United States and results in significant illness and sometimes death. The range of viruses of concern is expanding significantly and has become a true alphabet soup, with hepatitis A, B, C, D, E, and now hepatitis G as well. ...

Eukaryotic Parasites Eukaryotic parasites typically fall into one of two categories; either protozoa or helminthes. Protozoa are one-celled eukaryotes and can be transmitted by a vector or by water, as they have difficulty surviving in the environment since they are susceptible to desiccation. Transmission by the fecal-oral route is common, as in Giardia, which causes Beaver fever. Protozoa typically damage the host cell by replication, and do not release any toxins, and can inhabit the body both intracellular and extracellular. At some point in the life cycle of protozoa, a cyst form and tropozoite form normally exist. The cyst is more resistant to the environment and is normally infectious, while the tropozoite is the form that inhabits the body. Protozoa include Plasmodium falciparum, which causes malaria ...

Serological diagnosis of acute viral hepatitis A depends on the detection of specific anti-HAV IgM. Its presence in the patients serum indicates a recent exposure to HAV. Anti-HAV IgM becomes detectable in the blood within 2 weeks after infection, persisting at elevated levels for about 2 months before declining to undetectable levels by 6 months. However, sensitive immunoassays may occasionally detect anti-HAV IgM for up to 1 year after acute hepatitis A.. Hepatitis A virus (HAV) is endemic throughout the world, occurring most commonly in areas of poor hygiene and low socioeconomic conditions. The virus is transmitted by the fecal-oral route, and it is spread by close person-to-person contact and by contaminated food and water. Thorough cooking is necessary to inactivate HAV in contaminated foods. Outbreaks frequently occur in overcrowded situations and in high-density institutions and centers, such as prisons and health care or day care centers. Viral spread by parenteral routes (eg, exposure ...

Hepatitis A characteristically is an acute, self-limited illness associated with fever, malaise, jaundice, anorexia, and nausea. Among older children and adults, infection usually is symptomatic and typically lasts several weeks, with jaundice occurring in 70% or more. Symptomatic infection occurs in approximately 30% of infected children younger than 6 years of age; few of these children will have jaundice. Fulminate hepatitis is rare but is more common in people with underlying liver disease. Chronic infection does not occur.. Hepatitis A virus (HAV) is endemic throughout the world, occurring most commonly in areas of poor hygiene and low socioeconomic conditions. The virus is transmitted by the fecal-oral route, and it is spread by close person-to-person contact and by contaminated food and water. Thorough cooking is necessary to inactivate HAV in contaminated foods. Outbreaks frequently occur in overcrowded situations and in high-density institutions and centers, such as prisons and health ...
There is a silent epidemic of viral hepatitis types B and C in the WHO European Region, where 13.3 million people are estimated to live with chronic hepatitis B and 15 million people with hepatitis C. Worldwide, hepatitis B and C lead to chronic disease in about 500 million people. Together, they are the most common causes of liver cirrhosis and cancer.. Although a blood test shows when someone has viral hepatitis, most people infected with hepatitis B and C do not know it. Only 1 infected person in 5 is estimated to display acute symptoms. Even among such people, testing often does not occur, since acute symptoms are often mild or confused with influenza-like illness. If left untreated, hepatitis B and C may become chronic, and can lead to disease, cirrhosis and cancer of the liver.. There are five strains of viral hepatitis (types A- E), but types B and C account for the largest burden of disease in the WHO European Region, and thus are the main focus of effort.. While hepatitis A and E ...
World Hepatitis Alliance calls for immediate political action to counteract fatal trend. [London, 14 September] According to the Global Burden of Disease study released today, deaths caused by viral hepatitis have surpassed all chronic infectious diseases including HIV/AIDS, malaria and tuberculosis.. The study illustrates that in 2016, the total deaths caused by viral hepatitis, including liver cancer, acute cases, cirrhosis, hepatitis A, E, B, C and D account for 1.34 million deaths globally, exceeding tuberculosis (1.2 million), HIV/AIDS (1 million) and malaria (719,000).. These staggering death rates occurred despite recent advances in hepatitis C medications that can cure most infections within three months and the availability of highly-effective vaccinations for hepatitis B.. Its outrageous, but not surprising, that the Global Burden of Disease Report found that deaths related to viral hepatitis have surpassed HIV, TB and malaria said Charles Gore, President of the World Hepatitis ...
Summary An epidemic of infectious hepatitis has been described, involving at least 222 individuals in a college, for a total attack rate of 8 per cent. Cases were distributed throughout the campus population with great uniformity, with two exceptions: disproportionately low attack rates (0.4%) were observed in students who lived off campus, and disproportionately high attack rates (17 to 50%) were observed in student workers in the common dining hall. Although every evidence pointed to a common source and mode of infection, these could not be determined with certainty. The outbreak is described as a
The present invention discloses nucleic acid sequences which encode infectious hepatitis C viruses and the use of these sequences, and polypeptides encoded by all or part of these sequences, in the development of vaccines and diagnostics for HCV and in the development of screening assays for the identification of antiviral agents for HCV.
Hepatitis A is commonly spread from person-to-person through the fecal-oral route. Symptoms include jaundice (yellowing of the skin and eyes), fever, fatigue, loss of appetite, nausea, vomiting, abdominal pain, dark urine, and light-colored stools.. Vaccination is the best prevention against hepatitis A. Practicing good hygiene can also help prevent the transmission of hepatitis A. Wash hands thoroughly after using the bathroom, changing diapers, and before preparing or eating food. More information on hepatitis A is available on the Health District website. For up to date information on the nationwide Hepatitis A outbreak visit the CDC website.. This current outbreak of hepatitis A in our community is an unfortunate but important reminder of why vaccines are vital to both our individual and community health, said Dr. Joe Iser, Chief Health Officer of the Southern Nevada Health District.. Since March of 2017, the Centers for Disease Control and Prevention has assisted multiple states and local ...
Richard and Lindas Hepatitis A infections arose out of an extremely large outbreak in Western Pennsylvania in late 2003. The infections were linked by federal, state, and local health officials to green onions served in salsa prepared at a Chi Chis restaurant. Richard and Linda were health department-confirmed members of the outbreak. Richard and Linda dined at the implicated Chi Chis between September 14 and October 17, 2003, the period of identified exposure. The onset of their illnesses matched the expected incubation period for Hepatitis A. Finally, both Richard and Linda had laboratory confirmations of acute Hepatitis A virus (HAV) infection, i.e. positive IgM anti-HAV. On Sunday, October 12, 2003, Richard and Linda ate lunch at Chi Chis in the Beaver Valley Mall. On Tuesday, October 28, just days after visiting their son and daughter-in-law, Linda and Richard developed flu-like symptoms. Over the following days, their symptoms grew worse, particularly Richards. By early November, ...

Hepatitis A, caused by the hepatitis A virus (HAV), is a vaccine preventable disease. In Low and Middle-Income Countries (LMICs), poor hygiene and sanitation conditions are the main risk factors contributing to HAV infection. There have been, however, notable improvements in hygiene and sanitation conditions in many LMICs. As a result, there are studies showing a possible transition of some LMICs from high to intermediate HAV endemicity. The World Health Organization (WHO) recommends that countries should routinely collect, analyse and review local factors (including disease burden) to guide the development of hepatitis A vaccination programs. Up-to-date information on hepatitis A burden is, therefore, critical in aiding the development of country-specific recommendations on hepatitis A vaccination. We conducted a systematic review to present an up-to-date, comprehensive synthesis of hepatitis A epidemiological data in Africa. The main results of this review include: 1) the reported HAV seroprevalence

The means of hepatitis transmission varies depending upon the virus responsible for the inflammation. The hepatitis viruses A, E, and F are predominantly spread via the fecal-oral route through food or water that has been contaminated. These viruses are primarily responsible for epidemics of hepatitis in many less-developed regions of the world where crowded conditions and inadequate sanitation are often problems. The other main hepatitis viruses, B, C, D, and G, are chiefly spread through bodily fluids or blood, making their transmission through sexual activity and accidental contact with infected blood a common occurrence. Blood transfusions were also widely responsible for the transmission of the blood-borne varieties of hepatitis until adequate screening measures were introduced in the 1970s. Needle-exchange programs in some areas have also helped decrease incidence of the disease in recent years among intravenous drug users.
EXECUTIVE eirector of the Beacon Youth Initiative, BYI, Mr. Evoh Emmanuel has attributed the perpetuating global burden of viral hepatitis on lack of awareness at individual, community and government levels in the country and world at large. He observed that less than five percent of the people living with viral hepatitis worldwide were unaware of their condition, largely due to the disease being mostly asymptomatic and the lack of routine screening and awareness. Emmanuel made the assertion yesterday at an event marking the 2016 World Hepatitis Day in Lafia, Nasarawa State, with theme as Elimination of Viral Hepatitis. He called on the federal and state governments and other partners to take responsibility by scaling up hepatitis testing services and bproviding treatment to reduce needless deaths. Emmanuel revealed that his organisation had carried out a four-day activities to mark the 2016 Hepatitis Day at four different locations across the southern part of Nasarawa State. This years ...

In early 2015 a group of viral hepatitis experts within the HIV Europe Initiative formed a working group to develop a consensus definition for viral hepatitis. After discussions, meetings and several reviews the final two agreed upon definitions were approved by the EASL GB in early October 2015 and on Thursday 22 October EASL and HIV in Europe announced a consensus definition of late presentation for viral hepatitis. The announcement coincided with the European AIDS Conference in Barcelona and aims to encourage policy makers, health professionals, public health institutions and civil society organisations to implement this definition to improve the European surveillance of and response to the viral hepatitis epidemic.

A virus that causes hepatitis can spread from one person to another. Some hepatitis viruses spread when an uninfected person comes in contact with infected body fluids. Body fluids include blood, semen, or vaginal fluid. Other viruses are spread by contaminated food and water or by coming in direct contact with the stool (feces) of a person who is infected with the virus. In the early stage of infection, the type of hepatitis virus causing the infection may be hard to identify. But several weeks to several months after infection occurs, blood tests can show which of the viruses is causing hepatitis.. Most people with viral hepatitis recover on their own. Antiviral medicine can treat many cases of hepatitis. Some forms of hepatitis can become chronic and increase a persons chance of liver failure or liver cancer. ...

Salud pública Méx [online]. 2007, vol.49, suppl.3, pp.s377-s385. ISSN 0036-3634.. OBJECTIVE: Hepatitis A Virus (HAV) in Mexico has traditionally been considered a disease with a homogeneous pattern of transmission, high rates of infection at early ages, and infrequent complication rates. The purpose of this study was to take advantage of the 2000 NHS, a probabilistic population-based survey, in order to describe the seroepidemiology of HAV infection in Mexico. MATERIAL AND METHODS: This study is based on information obtained from the National Health Survey that was conducted in 2000. The present report is based on 4 907 randomly selected samples that were studied to determine the prevalence of HAV antibodies using immunoenzymatic assay. Sera were collected from November 1999 to June 2000. RESULTS: Seroprevalence among the general population was 81.3% ...
The World Hepatitis Alliance seeks to ensure that a unified global response to viral hepatitis is manifested in the comprehensive national strategies that all countries are being encouraged to develop in a timely manner. A solid strategic foundation exists upon which all countries can build. The components of this foundation are put forth in World Health Assembly resolutions WHA 63.18 and WHA 67.6 and in the WHO viral hepatitis strategic framework.34,35,36. As the resolutions and strategic framework reflect, we already know what to do in many regards in order to prevent new infections and to reduce suffering and death from viral hepatitis. Indeed, the section of resolution WHA 67.6 that is directed at governments itemises 16 key actions that could potentially have an enormous impact on hepatitis prevention and treatment (Box 5). The challenge is to apply this knowledge - which in many parts of the world will involve overcoming formidable barriers relating to complacency, ignorance, stigma and ...

Every year, July 28 is marked as World Hepatitis Day (WHD). It is a day dedicated to increase the global awareness and understanding of viral hepatitis and the diseases that it causes. The theme of this years WHD is Prevent Hepatitis. Act Now. Viral hepatitis is inflammation of the liver caused by a group of virus known as hepatitis A, B, C, D, and E. The liver is the largest internal organ. It is shaped like a pyramid and lies under the right ribs just beneath the right lung.. The liver is an indispensible organ. It has several important functions including: break down and storage of many of the nutrients absorbed from the intestine; production of most of the clotting factors that prevent excessive bleeding from cuts or injuries; release of bile into the intestines to help absorb nutrients (especially fats) as well as removal of harmful substances from the blood.. Annually, viral hepatitis affects 400 million people worldwide, causing acute and chronic liver disease and killing about 1.5 ...

Eliminating viral hepatitis by 2030 is firmly on the global health agenda.. The minister, who made the call at a press briefing to mark World Hepatitis Day, in Abuja, said the disease had become a silent killer because much importance had not been attached to dangers it posed to health.. The WHO baseline data previously revealed that although some of the 2030 targets, such as childhood vaccination and injection safety are within reach, there is a crucial need for all stakeholders, including policy makers, medical professionals and civil society to step-up efforts and work together to address access to effective treatment, diagnoses and mother-to-child transmissions.. Hepatitis A is caused by contaminated food and water and Hepatitis B is caused by unprotected sex and unsafe needle usage.. How can you catch one of the viruses? Peck reminded the increasing number of hepatitis related deaths and urged for efficient testing and early treatment in all parts of the world. Now, however, people are ...
May is Hepatitis Awareness Month. Hepatitis is an inflammatory condition of the liver, and when your liver is inflamed, its ability to function can be compromised. Hepatitis is most commonly caused by a viral infection, although there are other causes as well. Were concentrating on viral hepatitis in this blog.

Viral hepatitis is the inflammation of liver cells caused by viruses, and still one of the major health-care problems worldwide. A number of viruses to cause hepatitis are type A, B, C, D, E or G. Among these viruses leading to hepatitis, B and C are more troublesome being more prone to chronic illness which can cause the potentially fatal conditions of hepatocellular carcinoma (HCC) and/or liver failure. If immediate treatment is not initiated, liver transplant is the only option left. Over the past few decades there has been remarkable progress in diagnose and monitor all hepatitis virus infections for treatment and prevention. Nonetheless, important challenges remain to develop more effective and safe vaccines for prevention as well as antiviral agents to reduce viremia/viral load by inhibiting viral replication. The development and evaluation of antiviral agents through carefully designed clinical trials over the last 25 years has heralded a new dawn in the treatment of patients chronically

We describe a 74 year-old patient with chronic renal failure due to focal glomerulonephritis who was admitted to our department because of one-week jaundice and fatigue. Medical history was negative for any type of hepatitis or biliary tract lithiasis. Clinical examination revealed an icteric patient with upper right quadrant tenderness, hepatomegaly, dark-colored urine and colorless feces. Laboratory investigation of peripheral blood revealed anemia, lymphocytopenia, elevated serum urea and creatinine, transaminasemia, hyperbilirubinemia with direct bilirubin predominance and ã-GT and alkaline phosphatase elevation. Abdominal ultrasonography was within normal limits. Laboratory investigation for hepatitis A to E and liver related viruses revealed positivity for IgM immunoglobulins of hepatitis A and cytomegalovirus(CMV) virus. IgM CMV antibodies were 6-fold increased above the cut-off value while CMV IgG antibodies existed in titers below the cut-off reference value. IgM HAV antibodies were increased
Hepatitis A is a viral infection of the liver transmitted most commonly by fecal-oral contact from contaminated food or water, or from person to person via contaminated hands or oral-anal contact. Hepatitis A virus infects primarily humans. In 2005, 23 cases of hepatitis A were reported in Indiana for a rate of less than 1 case per 100,000 population (Table 1). This represents a decrease from 2004 (0.58). Figure 1 shows the number of reported cases per year for 2001-2005. The number of reported cases was highest during the spring and fall months (Figure 2). Figure 3 shows age-specific rates were greatest for infants under the age of 1 (1.16) and preschoolers aged 1-4 years (1.16), followed by adults aged 80 years and older (0.88). Females (0.35) were just as likely to be reported as males (0.36). The rate for whites (0.34) was higher than that for blacks (0.18); however, three cases (13%) did not report race data. In 2005, 11 Indiana counties reported cases of hepatitis A, but only Marion County ...

The compound 13-cis retinoic acid was first studied in the 1960s at Roche Laboratories in Switzerland by Werner Bollag as a treatment for skin cancer. Experiments completed in 1971 showed that the compound was likely to be ineffective for cancer and, surprisingly, that it could be useful to treat acne. However, they also showed that the compound was likely to cause birth defects, so in light of the events around thalidomide, Roche abandoned the product. In 1975, Gary Peck and Frank Yoder independently rediscovered the drug's use as a treatment of cystic acne while studying it as a treatment for lamellar ichthyosis, and published that work. Roche resumed work on the drug. In clinical trials, subjects were carefully screened to avoid including women who were or might become pregnant. Roche's New Drug Application for isotretinoin for the treatment of acne included data showing that the drug caused birth defects in rabbits. The FDA approved the application in 1982. Scientists involved in the ...
Moderate alcohol consumption 30-60 minutes before bedtime results in disruptions in sleep maintenance and sleep architecture that are mediated by blood alcohol levels.[2] Disruptions in sleep maintenance are most marked once alcohol has been completely metabolized from the body. Under conditions of moderate alcohol consumption where blood alcohol levels average 0.06-0.08% and decrease 0.01-0.02% per hour, an alcohol clearance rate of 4-5 hours would coincide with disruptions in sleep maintenance in the second half of an 8-hour sleep episode.[2] In terms of sleep architecture, moderate doses of alcohol facilitate "rebounds" in rapid eye movement (REM) and stage 1 sleep; following suppression in REM and stage 1 sleep in the first half of an 8-hour sleep episode, REM and stage 1 sleep increase well beyond baseline in the second half. Moderate doses of alcohol also increase slow wave sleep (SWS) in the first half of an 8-hour sleep episode.[2] Enhancements in REM sleep and SWS following moderate ...

... (development code GS-5734) is an antiviral drug, a novel nucleotide analog prodrug. It was developed by Gilead Sciences as a treatment for Ebola virus disease and Marburg virus infections, though it has subsequently also been found to show reasonable antiviral activity against more distantly related viruses such as respiratory syncytial virus, Junin virus, Lassa fever virus, and MERS-coronavirus.[1] Remdesivir was rapidly pushed through clinical trials due to the 2013-2016 West African Ebola virus epidemic crisis, eventually being used in at least one human patient despite its early development stage at the time. Preliminary results were promising and it was used in the emergency setting for the 2018 Kivu Ebola outbreak along with further clinical trials, until August 2019, when Congolese health officials announced it was ineffective compared to other treatments such as mAb114 and the Regeneron-produced REGN3470-3471-3479.[2][3][4][5][6][7][8] It may also help protect against Nipah ...

The vitamin thiamine also referred to as Vitamin B1, is required by three different enzymes to allow for conversion of ingested nutrients into energy. [13] Thiamine can not be produced in the body and must be obtained through diet and supplementation. [23] The duodenum is responsible for absorbing thiamine. The liver can store thiamine for 18 days.[13] Prolonged and frequent consumption of alcohol causes a decreased ability to absorb thiamine in the duodenum. Thiamine deficiency is also related to malnutrition from poor diet, impaired use of thiamine by the cells and impaired storage in the liver. [23]Without thiamine the Kreb's Cycle enzymes pyruvate dehydrogenase complex (PDH) and alpha-ketoglutarate dehydrogenase (alpha-KGDH) are impaired.[13] The impaired functioning of the Kreb's Cycle results in inadequate production of adenosine triphosphate (ATP) or energy for the cells functioning.
