What is the role of the Centers for Disease Control and Prevention (CDC) in disease investigation?

• A. Send teams to the location of a disease outbreak to assist local authorities
• B. Publish summaries submitted by the local health department
• C. Supervise research of disease worldwide
• D. Coordinate immunizations worldwide

Answer: (A)

When a disease outbreak occurs, the core action of the CDC in an investigation is to send teams to the outbreak site to assist local authorities. These field teams bring epidemiology, laboratory, and public health expertise to help quickly define the scope of the outbreak, identify the source, determine how it’s spreading, and implement control measures. They also support data collection, case finding, contact tracing, and risk communication, working alongside the local health department to strengthen the investigation and response. Publishing summaries or coordinating immunizations worldwide aren’t the primary on-site investigation roles; the key function is on-the-ground, federally supported field assistance to local authorities.
