Which of the following is a key function of the CDC?

• A. Creation of new vaccines
• B. Surveillance of health threats
• C. Management of healthcare facilities
• D. Development of healthcare policies

Answer: (B)

The key function of the CDC is surveillance of health threats. This involves systematically gathering, analyzing, interpreting, and disseminating health data to identify and monitor public health concerns at local, national, and global levels. By conducting surveillance, the CDC can detect outbreaks of diseases, track the spread of infections, and assess the health status of the population. This vital role allows for timely public health interventions and can guide policy decisions aimed at protecting public health.

While other options mention important activities in the healthcare field, they do not encapsulate the core surveillance role that the CDC plays in monitoring and responding to health threats. The establishment of new vaccines, management of healthcare facilities, and the development of healthcare policies are also significant, but they often rely on the information and insights gained through effective surveillance conducted by organizations like the CDC.
