Explanation:

Incidence rate of a population can be defined as the rate at which an disease occurs in a population.

The incidence of a population is calculated as

The number of new cases ÷ The population of the people

From the above question,

The number of new cases = 100

The population of the people = 100,000

The incidence = 100 ÷ 100,000

The incidence of syphilis in the population is 100 per 100,000
