Incidence of different types of viral hepatitis in Delhi, Uttar Pradesh and Rajasthan areas

A total of 428 sera samples from patients of acute sporadic viral hepatitis collected from Delhi (172), Uttar Pradesh (192) and Rajasthan (64) were tested for Hepatitis A Virus (HAV) and Hepatitis B Virus (HBV) markers. Non A non B was diagnosed by exclusion. The prevalence of HAV, HBV and non A non B in such cases was almost comparable at three places. The prevalence of HAV ranged between 15.7 and 20.3 per cent, HBV between 41.3 and 51.6 per cent while non A non B ranged between 28.1 and 43 per cent. The study signifies the role of non A non B in non-epidemic situations.
