“Whack-A-Mole” Microbiology – Emerging Infectious Diseases Emerging infectious disease = infectious disease whose incidence in humans has increased in the past 20 years or threatens to increase in the near future This is not really a hard and fast definition, but a good guideline NIAID’s (National Institute for Allergy and Infectious Diseases) categories for emerging and re-emerging diseases Group I = pathogens newly recognized in the past 20 years Group II = re-emerging pathogens Group III = agents with bioterrorism potential 9 factors which contribute to emergence/re-emergence of infectious diseases (know these!!) Mutation (microbial evolution) of disease Social & behavioral changes (what people do – including travelling) Advances in healthcare technology Ex: catheters help pts with urination, but it is more invasive -> higher chance of infection Changes in food & water distribution Natural disasters War Deliberate release of pathogens (bioterrorism) Climate/environmental change Demographics (where people live/ where they move to)
