Serum samples (850) from blood donors (400), pregnant women (384) and healthy staff members and students (66) were investigated by the hemagglutination inhibition [HAI] test for the presence of antibody against an .alpha. virus [Chikungunya (CHICK)] and 3 flaviviruses [Japanese encephalitis (JE), West Nile (WN) and Dengue type-2 (DEN-2)]. HAI antibody against JE, WN, DEN-2 and CHICK were detected in 46.6, 48.5, 32.4 and 3.0% of the sera, respectively. Group-B viral antibodies were detected in 77.4% of the sera tested; Group-A (CHICK) antibody was found in 3.0% of them. A higher percentage of positivity was obtained in the age group of 31-60 yr. Group-B arboviral infections are evidently prevalent in Kerala.
