Asthma & Community 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.

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

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.

Drought occurs when rainfall is lower than normal for a long time.  Droughts can last a single season, a whole year, or for many years and can affect a few hundred or millions of square miles. Drought can lead to public health problems.

Mold grows anywhere there is moisture but can be prevented. Exposure to damp and moldy environments may cause nasal stuffiness, throat irritation, coughing or wheezing, eye irritation, or skin irritation.
