Question 2

Search the CDC Current Outbreak List, found at HYPERLINK "https://www.cdc.gov/outbreaks/index.html" https://www.cdc.gov/outbreaks/index.html. Choose a current outbreak listed and discuss ways one might use primary, secondary, and tertiary prevention measures to reduce the impact of the disease.

Accepted Answer

Answers will vary, especially related to the disease chosen. However, students should address primary prevention- including health education, prevention, and promotion-as a means to prevent transmission of the disease. For example, the outbreak of hepatitis A among people experiencing homelessness and those who use drugs is a listed outbreak. Primary prevention of hepatitis includes vaccination, education about transmission, and promoting safe practices. Secondary prevention includes screening those who are listed as at risk for symptoms of hepatitis A. Tertiary prevention will include treatment of those who have been exposed but have not received the vaccination. Additionally, treatment would include management of symptoms for those who contract hepatitis A.
