Asthma & Community Health
The Asthma and Community Health Branch (ACHB) leads CDC’s fight against environmental-related respiratory illnesses, including asthma, and studies indoor and outdoor air pollution as well as links between climate and health.
Outdoor air quality in the U.S. has improved since the 1990s, but many challenges remain in protecting public health from air quality problems.
Asthma is a serious environmental health threat, but it can be controlled by taking medication and by avoiding contact with environmental “triggers” such as dust mites, furry pets, mold, tobacco smoke, and certain chemicals.
CDC’s Climate and Health Program is helping state and city health departments prepare for the specific health impacts of climate change that their communities will face.
