The prevalence rate of tuberculosis in one particular county in Texas is 7/1000 people, while the incidence rate for 2011 is 2/1000 people. Analyze this data and summarize the situation.

C)Prevalence rate is higher than incidence rate because the number of people still alive with tuberculosis is higher because of better treatments.

Explanation:

A)The data were collected incorrectly because the two values should match.

B)Incidence rate should really be higher than prevalence rate because it includes all new cases for the year.

C)Prevalence rate is higher than incidence rate because the number of people still alive with tuberculosis is higher because of better treatments.

D)Prevalence rate and incidence rate cannot be determined for the same disease.

The prevalence rate of a disease refers to the total number of cases of the disease that is present in the entire population at a specific period.

On the other hand, the incidence rate of a disease refers to the number of new cases of the disease that is present in a population within a specific period. It measures the rate at which new cases of the disease emerge in the population within a specified period.

While prevalence rate include all new and preexisting cases in a population, incidence rate deals with just new cases only.

Looking at the prevalence rate and incidence rate data, prevalence rate is higher than incidence rate. It simply means that the total number of people living with the disease outnumbers the number of new cases. This might be due to better treatment of the disease and or mitigation of spread of the disease to limit the emergence of new cases.

Hence, option C is the correct option.  

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
