title: Delta virus infections in and around Chandigarh, northern India: evidence for endemicity.
abstract: Delta virus infections, so far, have not been documented from India. Here we report for the first time the endemicity of delta virus infection in this geographical area. HBsAg positive serum samples from 81 patients and 10 healthy voluntary blood donors were tested for delta antigen. Seven out of 49 (14.3%) sporadic acute hepatitis cases, 3 out of 8 (37.5%) chronic renal failure patients requiring frequent haemodialysis, 1 out of 22 (4.6%) chronic liver disease cases and 1 out of 10 (10%) apparently healthy voluntary blood donors had delta antigenaemia.
