A second occurrence of this type of epidemic was the plague of Cyprian (also known as the plague of Commodus) in 251 to 266 A.D. (aao.org)
A manifestation of a disease or an occurrence of an event which creates a potential for a disease as a result of exposure to or contamination by a chemical agent. (who.int)

Understanding the basic modes of transmission for infectious diseases will help you accurately convey an epidemic's risk to the public. (journalistsresource.org)
As Rothenberg observed, "a substantial number of voices have raised the question of proven efficacy and point to the lack of demonstrable influence of PN on disease transmission" (6). (nccid.ca)
[ 1 ] Human-to-human transmission is ucommon except during epidemics of pneumonic plague. (medscape.com)

Pathogens traverse disciplinary and taxonomic boundaries, yet infectious disease research occurs in many separate disciplines including plant pathology, veterinary and human medicine, and ecological and evolutionary sciences. (springer.com)
In the past decade, infectious disease research also has captured the full attention of the ecological and evolutionary sciences. (springer.com)
This group will study fundamental questions about the behavioral, environmental and evolutionary factors underlying infectious disease epidemics and use this information to develop real-time models for particular localities, such as cities or states. (nih.gov)
These genomes can inform us of the spread and evolutionary changes of pathogens in the past, and hopefully help us understand which genes may be important in the spread of infectious diseases. (news-medical.net)
Future research will do more to understand how our genomes responded to such diseases in the past, and the evolutionary arms race with the pathogens themselves, which can help us to understand the impact of diseases in the present or in the future. (news-medical.net)

Article 4 All persons, conveyance and containers, as well as articles such as baggage, goods, postal parcels that may transmit quarantinable diseases are subject to quarantine inspection upon entering or exiting the country in accordance with these Rules, and entry and exit shall be allowed to them only after an approval is issued by the health and quarantine office. (china.org.cn)
Article 5 When a quarantinable epidemic victim is discovered by the health and quarantine organ, measures must be taken promptly in accordance with the rules stipulated in Chapter VIII of these Rules to place him in isolation and prevent other persons from being infected. (china.org.cn)
When a quarantinable epidemic suspect is found by the health and quarantine organ, he shall be dealt with in accordance with the rules stipulated in Chapter VIII. (china.org.cn)
Like most experts, Kinyoun and Wyman believed plague cases would eventually arrive at U.S. ports-especially San Francisco, which received heavy ship traffic from Asian cities with ongoing epidemics-and that only vigilant quarantine could keep the plague out. (nih.gov)

Its core research program focuses on modeling drug resistance, seasonal infectious diseases and the allocation of interventions. (nih.gov)

Models can't tell us what will happen, but they do allow us to explore a range of possibilities for disease containment," said Jeremy M. Berg, Ph.D., director of the National Institute of General Medical Sciences, the NIH component supporting MIDAS. (nih.gov)

In a deterministic model, individuals in the population are assigned to different subgroups or compartments, each representing a specific stage of the epidemic. (wikipedia.org)
There's no specific treatment for any of those three arboviral diseases, [ meaning Zika, dengue, and chikungunya]. (medscape.com)
Indicator-based surveillance uses reports of specific diseases. (cdc.gov)
A specific feature of infectious diseases is their ability to be transmitted between individuals. (ukessays.com)
This and other reviews in the series will contribute to advancing Canadian practice by providing information necessary to identifying commonalities in the practice of PN, challenges relating to specific diseases / infectious agents, and proposed strategies to address them. (nccid.ca)

Infectious diseases are a leading cause of global mortality, causing more than 13 million deaths a year. (ukessays.com)
Aerosolized Y pestis, causing primary pneumonic plague, has been recognized by bioterrorism experts as having one of the highest potentials as a bioterrorism agent due to its extremely high mortality, its high uptake into enzootic and epizootic animals as well as humans, and its ability to be spread over a large area. (medscape.com)

Humans was no official announcement of another are the reservoir of the disease, despite iso- epidemic until the year 1999. (who.int)
Further, by employing a comparative approach that is inclusive of microorganisms, plants, wild and domestic animals, and humans, we will deepen our understanding of disease for all of these fields. (springer.com)
The study of plant sexually transmitted diseases also has stimulated increased understanding of sexually transmitted diseases in animals and humans (Lockhart et al. (springer.com)

On February 7, 2021, the Ministry of Health (MOH) in the Democratic Republic of the Congo (DRC) announced that a case of Ebola virus disease (EVD) had been confirmed in Biena Health Zone, North Kivu Province. (cdc.gov)

Where 'STD' (sexually transmitted disease) appears in this document, it reflects use of the term in the original reference. (nccid.ca)

aegypti ), implicating these species as likely lin (Ig) M-capture ELISA with DENV antigen confi rmed epidemic or enzootic vectors ( 3 - 5 ). (folkhalsomyndigheten.se)

These types of cases are a concern to global health researchers because they echo a pattern seen in past epidemics. (ijpr.org)

For example, genetic variation in host resistance is commonly considered in plant pathology, but is less often explicitly considered in studies of animal diseases. (springer.com)

The disease is caused by a coccobacillus-shaped, gram negative bacterium referred to as Yersinia pestis . (medscape.com)
The disease is caused by the plague bacillus, rod-shaped bacteria referred to as Yersinia pestis . (medscape.com)

Expanding on his comments about the dengue situation in South America, Velayudhan stated that "climate change has played a key role in facilitating the spread of the vector, the mosquitoes, down south. (medscape.com)
