Define its common agent, reservoir, portal of exit, means of transmission, portal of entry, and host (the chain of infection).
How long is its incubation period?
Does it have a common source of the outbreak?
Does the CDC have active surveillance on this infectious disease?
Does herd immunity apply? Is it pandemic?
describe an outbreak of the infection and apply the science to the outbreak. You must construct an original epidemiological triad that is specific to the infection you chose.
