Epidemiology

The principal government agency responsible for tracking infectious diseases in the United States is the World Health Organization. National Institutes of Health. United States Department of Agriculture. Infection Control Committee. Centers for Disease Control and Prevention.

Centers for Disease Control and Prevention.

The number of new cases of a disease in a population over a specific period of time compared with the healthy population is the ______. prevalence rate epidemic rate incidence rate morbidity rate mortality rate

incidence rate

The Centers for Disease Control and Prevention assigns the most virulent microbes known to cause human disease to biosafety level 4. True False

t

The Centers for Disease Control and Prevention mandates that some diseases must be reported, while it is not necessary for others. This is so that statistics may be gathered for certain diseases. the incidence and prevalence for diseases of public health importance can be tracked. disease trends and areas of outbreak can be monitored for certain diseases. high-risk epidemics can be identified and dealt with as quickly as possible. All of the above answers validate why it is important to report certain diseases to the CDC.

Endemic:

An infectious disease that exhibits a relatively steady frequency over a long time period in a particular geographic locale.

Sporadic disease

Occasional cases are reported at irregular intervals in random locales.

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. Prevalence rate and incidence rate cannot be determined for the same disease. The data were collected incorrectly because the two values should match. Incidence rate should really be higher than prevalence rate because it includes all new cases for the year. Prevalence rate is higher than incidence rate because the number of people still alive with tuberculosis is higher because of better treatments.

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

Pandemic

Spread of an epidemic across continents.

Epidemic:
