Document Summary
Epidemiology has changes as technology advances (more advanced techniques) and as global travel becomes more common (more opportunities for pandemics) Infectious diseases (communicable) differ from non-infectious in terms of transmissibility. Likelihood the disease is transmitted from infected to susceptible subject) Must consider number of cases as well as how many resulted from initial case (more cases you have, the more cases you get) Basic reproductive number (r0): the average number of secondary infections when a single infectious case is introduced into a completely susceptible population. R0 > 1 means there can be an epidemic (each primary infectious individual is causing > 1 secondary infections) R0 = 1 means it will stay an endemic. This number is an average because differences among populations will influence. R0 (busy city area means more people likely to run into infected person) Useful foe estimating the number of people needed to vaccinate to control disease and for estimating initial slope of epidemic curve.
