Sylvatic yellow fever activity in Trinidad, 1988-1989.

Of a total of 18,068 mosquitoes (361 pools) collected in south-eastern Trinidad forests from December 1988 to May 1989, 47 species belonging to 14 genera were identified. Five yellow fever virus isolates were made from Haemagogus janthinomys and one from Sabethes chloropterus. All the other pools of mosquitoes examined were negative for the virus. The mosquito isolates were made in December and January. In addition, in late February and early March, 2 infected howler monkeys (Alouatta sp.) were detected. Since March, despite continued surveillance, no yellow fever virus has been detected in mosquitoes or monkeys. There has been no reported human infection.

Parasitic infections in young Jamaicans in different ecological zones of the island.

Data are presented for the first country wide prospective study on gastrointestinal tract parasitic infections done in Jamaica. Samples from 2,947 young Jamaicans drawn from all ecological zones and from all parochial divisions of the island were analyzed. Pica was practised by 8.6%. Generally, prevalence of organisms was as follows: Trichuris trichiura (12.3%), Ascaris lumbricoides (9.5%), hookworm (2.2%), Strongyloides stercoralis (0.3%), Giardia lamblia (6.3%) and Entamoeba coli (7.7%). Several other spp. of protozoans were recorded. Prevalence of A. lumbricoides, T. trichiura and Necator americanus was significantly greater in upland than in lowland (both urban and rural), while the situation was reversed for G. lamblia-infections. Greatest variations were age-related. A. lumbricoides and T. trichiura reached peak prevalence of 15.3 and 20.5% respectively in 5-9-year-olds, while hookworm peaked later at 15-19 years of age. Suggestions are made for a national and even regional antihelminthic program for the mass treatment of pre- and primary school age children.
