The prevalence rate of HBV infection in our study was 34.7% (146/420), higher than the prevalence rate of 13.9% (178/1280) in the general population (P (scirp.org)

to check the knowledge presented by the nursing staff on the mode of transmission of hepatitis B virus (HBV) and the resulting damage to human health and to identify the knowledge of the nursing staff on prevention measures used to avoid occupational infection by this virus and, further, to investigate the immunization situation of the nursing staff against HBV. (bvsalud.org)
The habit of resurfacing needles used on patients is still observed in the daily activities of health professionals 7,8 , in spite of the current guidelines for prevention and control of these occupational infections. (bvsalud.org)
Maintaining a healing environment for all includes the prevention of infections from our pets and other animals. (ccp.edu)

Effective prophylactic measures that include those for potential zoonotic infections should reduce the risk for HEV transmission in this population. (cdc.gov)
The genotypes have a distinct geographical distribution and are used in tracing the evolution and transmission of the virus. (wikipedia.org)
They affect the liver and have a variety of etiologies and mechanisms of transmission. (ccp.edu)
Vertical transmission from mother to newborn baby is one of the mechanisms by which chronic hepatitis virus infection spreads, besides infections from contaminated needles and syringes and sexual contact. (bvsalud.org)
Conclusion: The prevalence of HBV chronic infection among pregnant women in Bor, Jonglei State, is high hence there is a need for established public health interventions that can lead to a reduction of HBV vertical transmission. (bvsalud.org)
Treatment of pregnant women with HBV chronic infection using anti-viral medications during pregnancy might curb the vertical transmission rates. (bvsalud.org)
In 1992 HCV genotyping and sequencing were developed as tools to follow transmission chains in nosocomial HCV infections e.g. children with cancer. (lu.se)

therefore, patients with hepatitis C infection should abstain from alcohol use. (aafp.org)

however, proposed mechanisms include cryoglobulin deposition in the vasa nervorum and HCV-mediated vasculitis. (cochrane.org)
Other mechanisms that could contribute to vasculitis include autoantibodies or T cells 1 . (vaccinesafety.edu)
These viruses, which include the hepatitis A and E viruses (HAV and HEV, respectively), infect millions of individuals worldwide and pose significant threats to public health. (cshlpress.com)

It occurs uncommonly as a coinfection with acute hepatitis B or as. (msdmanuals.com)

Chronic hepatitis B virus (HBV) infection in endemic areas usually starts since infancy and early childhood and persists lifelong. (mendeley.com)
