The San Diego Regional Asthma Coalition (SDRAC) is pleased to present the first annual San Diego County Asthma Report Card. Its primary purpose is to summarize and document key data on asthma and asthma-related issues. By compiling data from several sources, we have gained a better understanding of asthma in San Diego County and the areas and populations most in need of asthma-related services. Currently there is no comprehensive asthma surveillance system in place, making it difficult to accurately track and measure the social, human, and economic impact of asthma. Nonetheless, the data presented in this Report Card provides useful information regarding trends and disparities in the San Diego Region.
