The answer is Centers for Disease Control and Prevention.
The World Health Organization (WHO) is an international agency responsible for global public health. While it plays a crucial role in tracking infectious diseases worldwide, it is not a government agency specific to the United States.
The Centers for Disease Control and Prevention (CDC) is the principal government agency in the United States responsible for tracking and controlling infectious diseases. It conducts research, provides information, and implements measures to prevent and control disease outbreaks.
An Infection Control Committee typically exists within hospitals or healthcare facilities to manage and prevent infections within that specific institution. It is not a national government agency.
The National Institutes of Health (NIH) is a part of the U.S. Department of Health and Human Services and is primarily focused on medical research. While it contributes to understanding diseases, it is not the main agency for tracking infectious diseases.
The United States Department of Agriculture (USDA) deals with policies related to agriculture, forestry, and food. It is not primarily responsible for tracking infectious diseases in humans.
