Answer:
San Carlos County
Step-by-step explanation:
a) Data and Calculations:
Number of cases of tuberculosis reported in the first half of 2001 = 17
Number of cases of tuberculosis reported in the second half = 18
Total number of cases reported = 35 (17 + 18)
Population of the county at the beginning of 2001 = 204,500
Population of the county at the end of the year = 215,000
Average population for the year = 209,750 (204,500 + 215,000)/2
Therefore, the incidence rate of tuberculosis in the county = 35/209,750 * 100
= 0.000167
b) Since the incidence rate is <1, it suggests that the population of San Carlos County is at a very reduced risk of exposure to tuberculosis. This means that only 1 in 6,000 (209,750/35) people are exposed to the disease in the county.
