Per- and Polyfluoroalkyl Substances (PFAS) and Your Health

alert icon

CDC’s and ATSDR’s response to the serious public health threat caused by the COVID-19 pandemic includes agency guidance on social distancing—or, limiting gatherings and increasing the physical distance between people—to stop further spread of the coronavirus. In compliance with this guidance, we paused  Per- and Polyfluoroalkyl Substances (PFAS) activities, such as in-person community meetings.

At this time, CDC and ATSDR are resuming some field activities with additional health and safety precautions to minimize the risk of transmission of COVID-19.

We encourage everyone to do their part by following guidelines and social distancing to stop community spread of the virus.

Please check our website periodically for PFAS updates, and click on COVID-19 to learn more about the virus. If you have questions about ATSDR’s PFAS efforts, please send them to our email inbox at and we will respond as quickly as possible.

What are the health effects of PFAS?

Human exposure to per- and polyfluoroalkyl substances (PFAS) is a public health concern

Human exposure to per- and polyfluoroalkyl substances (PFAS) is a public health concern that the Centers for Disease Control and Prevention’s (CDC) National Center for Environmental Health (NCEH) and the Agency for Toxic Substances and Disease Registry (ATSDR) are helping our local, territorial, tribal, state, and federal partners address. Over the last decade, interest in PFAS has been growing. ATSDR and our state health partners are investigating exposure to and possible health effects associated with PFAS in more than 30 communities across the United States.
