Document Summary
Asks a specific study question (usually about how a particular exposure affects an outcome) Looks at exposures and outcomes of interest in these people over time. Relies on data/exposures and/or outcomes that have already been collected (through medical records or as a part of another study) Factors associated with the emergence of new viruses. Humans are constantly providing new ways to meet viruses: air travel, dams and water impoundments, irrigation, rerouting of wildlife migration patterns, wildlife parks, hot tubs, air conditioning, blood transfusion, day care centers. Human demographics, behavior, vulnerability more people, more crowding, changing sexual habits, injection drug use, changing eating habits, more populations with weakened immune system. Economic development, land use, changing ecosystems increasing population densities and urban poverty encourage the spread of water- and air-borne viruses; changing ecology influencing waterborne, vectorborne disease transmission; more exposure to wild animals and vectors.
