How can epidemiologist differentiate between common-source and host-to-host epidemics based only on the incidence of disease?
What will be an ideal response?
Answer: Common-source epidemics result from a single contaminated source, which can be transmitted in any possible manner. Host-to-host epidemics result from person-to-person contact. Common-source epidemics usually involve a large population of individuals suddenly becoming ill, and host-to-host epidemics generally have a more gradual increase and decrease in the number of diseased individuals.
