Post-epidemic serological survey for JE virus antibodies in south Arcot district (Tamil Nadu).
Following an extensive epidemic of Japanese encephalitis (JE) in 1981, a serological survey was carried out in the South Arcot district of Tamil Nadu in April 1982. Serum specimens were obtained from 10 villages with serologically proven infections and 6 villages with no reported case of encephalitis during the 1981 epidemic. The serum specimens tested for haemagglutination inhibition, complement fixing and neutralizing antibodies, showed a high prevalence of JE (49.17%), West Nile (40.78%) and dengue (18.14%) viruses with predominance of JE. The prevalence did not differ between the villages with or without Japanese encephalities. There was also no difference between the family members and neighbours.
