There were 100 new cases of syphilis last year in a given population of 100,000 people. At that time, 500 people in this population already had syphilis. The incidence of syphilis in this population is __________.
a. 100 per 100,000
b. 500 per 100,000
c. 1000 per 100,000
d. 5000 per 100,000
Answer:
a. 100 per 100,000
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
