Asthma is a disease that affects the lungs and makes it difficult to breath. It is a serious health concern affecting many adults and children in California. Research has shown that asthma is exacerbated by elements in the environment (e.g. air pollution).
To help further understand the relationship between asthma and the environment, the California Environmental Health Tracking Program (CEHTP) is providing data and information to help track asthma in California.
