  1. The population of a state is 2,100,000. In a surveillanceproject lasting three months, investigators found communicabledisease reports documenting one case of anthrax, three cases ofmumps, 132 cases of pertussis, 27 cases of tuberculosis, 10 casesof primary and secondary syphilis, and 374 cases of gonorrhea.

Calculate the ratio of cases to population for each disease.Then, calculate the case rate (per 100,000 population per year) foreach disease.

Calculate the ratio of cases to population for each disease.

Anthrax- 1 case for 3 months ratio- R=X/Y thus 1/2,586,000

Mumps-    …………………………… ratio- R=X/Y thus3/2,586,000 reduced to 1/862,000

Calculate the case rate(per 100,000 population per year) foreach disease

Anthrax- 1 case per 3 months thus 4 per year ……. [4/2,100,000] *100,000 = 0.19

Mumps- 3 cases per 3 months thus 12 per year …..[12/2,100,000]*100,000= 0.57
