Document Summary

Epidemiologists (health detectives: collect/compile data about sources of disease and risk factors, design infection control strategies, prevent or predict spread of disease, use expertise in diverse disciplines including ecology/microbiology/sociology/statistics/psychology. Influences our daily lives (hand washing, waste disposal, restaurant/food inspection/water treatment) Communicable (contagious) disease: transmitted from one host to another, measles,colds, influenza, transmission determined by interactions between environment+ pathogens. + host: control of any of these factors may break infection cycle, improved sanitation, antimicrobial medication, vaccination. Collect data that characterize occurrence (time/place/individuals affected) of an outbreak used to compile risk factors for spread. Common-source epidemic/outbreak: rapid rise in cases suggests exposure to single source of pathogen, requires tracing to find what all victims have in common i. e food poisoning from a contaminated product. Propagated epidemic slow rise in cases suggests contagious disease spreading in population: 1st case is call the (cid:498)index case(cid:499) or (cid:498)patient zero(cid:499, requires contact tracing to find potential new victims.
