Step-by-step explanation:
The Centers for Disease Control and Prevention (CDC) and the U.S. Public Health Service (PHS) play important roles in protecting public health in the United States.
The CDC is responsible for promoting and protecting the health of the American people. It collects data on notifiable diseases, which are diseases that must be reported to the CDC. The CDC uses this information to track disease outbreaks, develop prevention strategies, and provide guidance to healthcare professionals and the public.
The PHS is a division of the Department of Health and Human Services and consists of several agencies, including the CDC. The PHS provides leadership in public health and coordinates federal efforts to improve the nation's health. It supports medical research, provides healthcare services to underserved populations, and responds to public health emergencies.
