cord-300793-tuq8z6gm	Weiss, Robin A	Social and environmental risk factors in the emergence of infectious diseases	2004		.txt	text/plain	5853	273	47	About 30 new diseases have been identified, including Legionnaires' disease, human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS), hepatitis C, bovine spongiform encephalopathy (BSE)/variant Creutzfeldt-Jakob disease (vCJD), Nipah virus, several viral hemorrhagic fevers and, most recently, severe acute respiratory syndrome (SARS) and avian influenza. Emerging infectious diseases in humans comprise the following: first, established diseases undergoing increased incidence or geographic spread, for example, Tuberculosis and Dengue fever; second, newly discovered infections causing known diseases, for example, hepatitis C and Helicobacter pylori; and third, newly emerged diseases, for example, HIV/AIDS and SARS. Although some of the apparent increase in infectious disease may be attributable to better diagnostic methods and surveillance, there seems little doubt that more incidents are occurring, and have the potential to spread more widely than 50 years ago, as outbreaks and spread of infections like Nipah virus and SARS would not have passed unnoticed.	./cache/cord-300793-tuq8z6gm.txt	./txt/cord-300793-tuq8z6gm.txt
