Seroprevalence of Hepatitis B Surface Antigen positive Patients Attending a Tertiary Care Hospital in Srikakulam, Andhra Pradesh.
Keywords:
Hepatitis B, HBsAg, Prevalence, Srikakulam.Abstract
Background: Hepatitis B virus (HBV) infection continues to be a serious public health problem globally and studying the prevalence of HBV infection in a geographical area aids in establishing magnitude of the problem. A teaching hospital based population study of Hepatitis B surface antigen (HBsAg) is a strong indicator of true HBV infection rate in the community as large number of patients from different backgrounds attend the hospital.
Methods: A one step rapid immunochromatographic method for detection of HBsAg was performed to diagnose HBV infection. 24,028 sera samples were tested over a period of one year 9 months.
Result: Out of the 24,028 samples tested for HBsAg, 733 (3.05%) were found to be positive for HBsAg. Positivity rate was more among males 440 (60.02 %) than females 293 (39.97 %) and the most common age group in males was 41-50 years (23.18 %) followed by 31- 40 years (22%).In females, commonest age group was 21-30 years (38.22%) followed by 31-40 years (14.67 %).
Conclusion: The study helps to know the magnitude of viral transmission in the community & to know the at risk age groups.Seroprevalence of HBsAg in Srikakulam, Andhra Pradesh was found to be 3.05% which is in accordance with the national average of 2-7 % and it falls into intermediate zone of HBsAg prevalence according to WHO.
