Document Summary
Integration of concepts, tools & approaches from variety of other disciplines to tackle problems; disciplines include (not limited to): mathematical modelling, qualitative research methods, public health. Epidemiologists not only deal with multi-faceted issues but also continually look for ways to modify/reinvent traditional approaches. Infectious diseases: mathematical model most often applied to understand infectious disease. Are concerned with cases & with number of cases that might occur: the more cases you have, the more cases you get. Di er in terms of transmissibility (ease/likelihood disease is transmitted from infected to susceptible subject) & fact that disease control requires a level of herd immunity for control: infectious (communicable): hiv, measles, polio, smallpox, malaria, q-fever, rabies, Sars, ebola: non-infectious (non-communicable): diabetes, celiac disease, cancer, osteoporosis. Two important factors to look at when trying to understand infectious diseases: reproductive numbers. Basic reproductive number (r0): average number of secondary infections when single infectious case is introduced into a completely susceptible population.
