Brief summary

The Thousand Asian American Study or TAAS aims to test 2,000 foreign-born and children of foreign born Asian Americans residing in Sacramento county residents for HBV and (2) counsel at least 90% of those whose screening results are positive for HBV.

Detailed description

The Thousand Asian American Study or TAAS aims to better understand the factors associated with testing for hepatitis B viral (HBV) testing among foreign-born Asian and African adult residents of Sacramento county, characteristics of those infected with HBV, and the efficacy of follow-up and linkage to care for those infected with HBV, and develop a research platform for future studies. Thus, what the investigators want to do is 1) test 2000 foreign-born Sacramento county residents for HBV and (2) counsel at least 90% of those whose screening results are positive for HBV. The investigators want to better characterize factors associated with HBV testing and factors that may differentiate those determined to be free of infection, infected with HBV, and those with resulting primary liver cancer.
