Question

below is a graph of the real - time spread of a disease outbreak. for this disease, people begin showing symptoms quite soon after they become contagious.
in this scenario, the quarantine rate was 25%. what would you expect to happen if we increased the quarantine rate to 75%? check all that apply. (note that you only have two attempts on this problem.)
a. the peak of the blue curve would move to the right, meaning the worst of the disease would happen at a later date.
b. the peak of the blue curve would move to the left, meaning the worst of the disease would happen at a later date.
c. the blue curve would remain unchanged, meaning a higher quarantine rate would not impact the spread of the disease.
d. the peak of the blue curve would be higher, meaning the maximum number of people who had this disease at one time would increase.
e. the peak of the blue curve would be shorter, meaning the maximum number of people who had this disease at one time would decrease.

Explanation:

When the quarantine rate increases, fewer people are available to spread the disease. This leads to a slower spread initially. A higher quarantine rate means that the disease has less opportunity to infect new people quickly. As a result, the peak of the curve (which represents the worst of the disease in terms of number of cases at a time) will be shorter (lower in height) because there are fewer simultaneous infections. Also, since the spread is slower, the peak will occur at a later date (move to the right) as it takes more time for the disease to reach its maximum number of cases under the more restrictive (higher quarantine rate) conditions.

Answer:

A. The peak of the blue curve would move to the right, meaning the worst of the disease would happen at a later date.
E. The peak of the blue curve would be shorter, meaning the maximum number of people who had this disease at one time would decrease.
