The Hepatitis B Team at the Charles B. Wang Community Health Center has been presenting their latest research on hepatitis B virus (HBV) at local conferences.

To assess trends in HBV infection and immunity, the Hepatitis B Team performed a chart review of adults who received HBV screening with three blood tests.  The team learned the following:

Nov - Hep B chart 2

Nov - Hep B map 3

Patients born in the Fujian province of China had more than double the HBV burden (75% were infected at one point) compared to patients who were born in surrounding provinces.

These findings reflect that the universal hepatitis B vaccination after 1980 was effective, however, the decline in vaccine immunity and increase in susceptibility among U.S.-born persons born after 1985 is concerning. These results also demonstrate the importance of testing patients with all three HBV blood tests to identify and counsel patients with HBV infection and to assess the efficacy of public health interventions.

This research was conducted by Dr. Amy Shen Tang, Janice Lyu, and Qingqing He of The Hep B Team. Their poster, “Assessing trends in hepatitis B virus infection and immunity at a community health center with universal screening practices,” was presented at the 3rd Annual NYU Health Disparities Symposium and at the 2017 American Association for the Study of Liver Diseases Conference.
