Answer

The minimum number of days that an unvaccinated person should be kept in quarantine after potential exposure to measles is 21 days. This duration is based on the incubation period of the measles virus, which averages around 10 to 12 days, but can range from 7 to 21 days. Therefore, to ensure that the individual does not pose a risk of spreading the disease, they should ideally be monitored and kept in quarantine for the full 21 days.
