Emerging Infectious Disease

An emerging infectious disease (EID) is an , AIDS ;¹ new infections resulting from change or Evolution of an existing Organism (e.g., Influenza ); a known infection which spreadsto a new geographic area or population (e.g., West Nile Virus ; previously unrecognized infection appearing in an area undergoing ecologic transformation; or, pre-existing and recognized infectious agents ''reemerging'' as a result of Drug Resistance in a known agent or a breakdown in Public Health measures. (e.g. Tuberculosis ).

MECHANISMS OF EMERGENCE/REEMERGENCE

Microbial adaption e.g. Genetic Drift and Genetic Shift in Influenza A

Changing human susceptibility e.g. mass immunocompromisation with HIV/AIDS

Climate and weather e.g. diseases with Zoonotic Vectors such as West Nile Disease (transmitted by Mosquitoes ) are moving further from the tropics as the climate warms

Change in human Demographics /trade e.g. rapid travel enabled SARS to rapidly propagate around the globe

Economic development e.g. use of Antibiotics to increase meat Yield of farmed cows leads to Antibiotic Resistance

Breakdown of public health e.g. the current situation in Zimbabwe

Poverty and social inequality e.g. Tuberculosis is primarily a problem in low-income areas

War and Famine

Lack of political will e.g. HIV

Bioterrorism e.g. 2001 Anthrax Attacks
