Health disparities are differences in the incidence, prevalence, and mortality of a disease and the related adverse health conditions that exist among specific population groups. These groups may be characterized by gender, age, race or ethnicity, education, income, social class, disability, geographic location, or sexual orientation. These health disparities are one reason why HIV/AIDS, viral hepatitis, STDs, and TB take a greater toll in one population group over another. Find information about how these diseases affect Asian populations.


In 2014, Asians made up 5% of the American population and accounted for 2% of HIV infection diagnoses. Asian American rates of HIV infection are very low compared to other racial/ethnic groups.
