HBsAg was screened by Reverse Passive Haemagglutination Test (RPHA) and was confirmed by ELISA test in 157 pregnant females and their newborns. Anti-HBc and IgM anti-HBc was done in these cases by enzyme immuno-assay. The overall prevalence of HBsAg in mothers was 16 out of 157 (10 percent) and in cord blood of newborns 5 per cent The transplacental transmission was found in eight of 16 (50 per cent) HBsAg positive mothers. Anti-HBc was present in 12 out of 16 (75 per cent) HBsAg positive mothers and, of these, seven (58 per cent) neonates acquired HBsAg infection. IgM anti-HBc was present in seven out of eight (88 per cent) HBsAg positive neonates, suggesting active in utero infection. Fourteen out of 16 (88 per cent) neonates born to HBsAg positive mothers were alive and healthy, one was stillborn and one had a congenital anomaly.
