Question 9

Of a particular disease is defined as the number of new cases of that disease in a defined population during a specific time period. Example: The number of new cases of Chlamydia in the US during 2016.

Answer 9

Incidence

Question 10

Usually expressed as the number of new cases of a particular disease that occurred during a specified time period and per specifically defined population.

Answer 10

Morbidity Rate

Question 11

During 2016 in the United States:

The Incidence of Chlamydia was 1,598,354 new cases.

The Morbidity Rate of Chlamydia was 497 per 100,000

population. Interpretation: For every 100,000 citizens, you would expect to find 497 cases of Chlamydia.
