Final answer:
The CDC monitors public health and infectious diseases in the U.S., reporting data through systems like the NNDSS and publications such as the MMWR, including reports on HIV and pertussis.
Step-by-step explanation:
In the United States, the Centers for Disease Control and Prevention (CDC) plays a crucial role in public health by monitoring and protecting against infectious diseases. The CDC operates several surveillance systems, including the National Notifiable Diseases Surveillance System (NNDSS), which collects data on notifiable diseases from state and local health agencies. This information is then compiled and published in the Morbidity and Mortality Weekly Report (MMWR), a key resource for health professionals and the public to stay informed on the prevalence and incidence of diseases nationwide. Additionally, the CDC releases detailed surveillance reports on various diseases, such as the HIV Surveillance Report and the Pertussis Surveillance Reports, providing valuable data on the spread and management of these conditions.
