If the incubation period of measles is 10-12 days, the most likely time of exposure for the study-abroad student is: "August 22-24" (Option B)
The incubation period is the time between when germs enter the body and when the first signs of a disease develop. Chickenpox, for example, has an incubation period of 14-16 days.
This is one of the reasons why the notion of incubating conditions monitoring plates at high temperatures of 30-35°C for 48 hours for bacteria recovery and then at low temperatures of 20-25°C for 72 hours for fungal growth is supported.
