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.
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. Asthma 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.
Carbon monoxide (CO) is an odorless, colorless gas that can cause sudden illness and death. It is found in combustion fumes produced by cars and trucks, generators, stoves, lanterns, burning charcoal and wood, gas ranges, and heating systems.
