Later, for about six decades no information about the status of the disease in these \nislands was available. In the late 1980s leptospirosis reappeared among the settler population \nand several outbreaks have been reported with high case fatality rates. Besides settlers, these \nislands are the home of six primitive tribes of which two are still hostile. These tribes have \nample exposure to environment conducive for transmission of leptospirosis. Since no \ninformation about the level of endemicity of the disease among the tribes is available, a \nseroprevalence study was carried out among all the accessible tribes of the islands. A total of \n1557 serum samples from four of the tribes were collected and examined for presence of \nantileptospiral antibodies using Microscopic Agglutination Test (MAT) employing 10 \nserogroups as antigens. An overall seropositivity rate of 19\u00b71% was observed with the highest \nrate of 53\u00b75% among the Shompens. The seropositivity rates in the other tribes were 16\u00b74% \namong Nicobarese, 22\u00b72% among the Onges and 14\u00b78% among the Great Andamanese. All of \nthe tribes except the Onges showed a similar pattern of change in the seroprevalence rates with \nage. The prevalence rates were rising from low values among children to reach a peak in those \naged 21\u201340 years and then declined. Among Onges the seroprevalence rates continued to rise \nbeyond 40 years. In all the tribes, seroprevalence rates were found to be significantly higher \namong the males. The commonest serogroups encountered were Australis followed by \nGrippotyphosa, Icterohaemorrhagiae, Pomona and Canicola.<\/jats:p>","DOI":"10.1017\/s0950268899002435","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T13:23:42Z","timestamp":1027776222000},"page":"423-428","source":"Crossref","is-referenced-by-count":15,"title":["Leptospiral infection among primitive tribes of Andaman and \nNicobar Islands"],"prefix":"10.1017","volume":"122","author":[{"given":"S.
