Educational information for kids about pollution is presented by NIEHS.

Asthma patients seem to be more prone to viral infections, and NIEHS scientists believe that the cells that line these patients' airways, cause this result by overproducing TGF-beta1, a protein that promotes viral growth. This study seeks participants with and without asthma to contribute airway cell samples.

If you or your child has been diagnosed with asthma, work with your doctor to learn how manage it yourself. You can work with your doctor to develop a treatment plan, called an asthma action plan.

Most people who have asthma are treated with daily medicine, called long-term control medicines, along with inhalers containing medicine for short-term relief during an asthma attack or when symptoms worsen.

How often asthma symptoms occur may depend on how severe, or intense, the asthma is, and whether you are exposed to allergens. Some people have symptoms every day, while others have symptoms only a few days of the year.

You may have an increased risk of asthma because of your environment or occupation, your family history or genes, other medical conditions, your race or ethnicity, or your sex.

The exact cause of asthma is unknown, and the causes may vary from person to person. However, asthma is often the result of a strong response of the immune system to an allergen in the environment.
