CDC

The CDC Health Alert Network and outbreak pages are official communications channels of the U.S. Centers for Disease Control and Prevention, a federal science agency funded by Congress and housed under HHS. They publish factual, science-based alerts about disease outbreaks and public health threats without an ideological editorial stance. Since January 2025, HHS has imposed political review requirements on CDC communications, and the volume of health alerts issued has fallen sharply compared to prior years, raising concerns among public health officials about gaps in outbreak warning.
