There is sudden increase in the number of ringworm infections in an urban city. The increase is not seen in other towns or countries. This is an example of:
Epidemic
Endemic
Pandemic
Prevalence
The Correct Answer is A
A. An epidemic refers to a sudden increase in the number of cases of a disease above what is normally expected in a specific area or population. The localized nature of the increase in ringworm infections supports this classification.
B. Endemic refers to a disease or condition regularly found among particular people or in a certain area; it does not account for the sudden spike in infections.
C. A pandemic involves widespread outbreaks affecting multiple countries or continents, which does not apply here.
D. Prevalence measures how widespread a disease is within a population, but it does not reflect sudden increases.
