C) there were 12.43 new cases of tuberculosis for every 100,000 people in the United States in the year 2000.

D) there were 12.43 tubercle bacilli per 100,000 microbes in the United States in the year 2000.

Answer 1

The incidence of tuberculosis in the year 2000 in the United States was 12.43 in every 100,000 people.

Step-by-step explanation:

The correct answer is option A) 12.43 in every 100,000 people in the United States had tuberculosis in the year 2000.

The incidence of tuberculosis is a measure of the number of new cases of the disease in a population over a specified time period. In this case, the incidence of tuberculosis in the year 2000 in the United States was 12.43 per 100,000 cases. This means that out of every 100,000 people in the United States, 12.43 were diagnosed with tuberculosis in the year 2000.

To calculate the incidence rate, you divide the number of new tuberculosis cases (12.43) by the population at risk (100,000) and multiply by the appropriate factor (in this case, 100,000).
