Concept explainers
To answer:
According to the graphical representation, which epidemic disease affects many numbers of people during the first three days?
Concept introduction:
In an epidemic, a disease occurs at a greater frequency than the expected in a specific area or population. In the graph, the epidemic of two diseases is seen, which affect patients for only one day. Neither the blue disease nor the red disease is treatable and does not need any treatment. In the graph, both epidemics begin at the same time.
To answer:
What could explain the short time course for the red epidemic?

To answer:
Why was the blue epidemic longer lasting?
