ABSTRACT
Simultaneous or sequential circulatin of dengue serotypes 1, 2 and 4 has been detected in several Caribbean countries. This may increase the chances of persons experiencing secondary infections with heterotypic dengue serotypes. Consequently there may be an increased risk of dengue haemorrhagic fever/dengue shock syndrome. Furthermore, Caribbean populations may not have been exposed to dengue serotype 3 in over 20 years and a large proportion of the population may not have immunity to this virus. Dengue type 3 has been recently isolated during epidemics in Central America and its introduction poses a further threat to the Caribbean. Sentinel surveillance was undertaken in a pilot study during August to December 1995 to improve the monitoring of Dengue serotypes on the islands of Jamaica, Trinidad and Dominica. Virological investigations were performed on a total of 92 patients who presented at designated community and hospital health care facilities on the 3 islands. Dengue virus types 1 and 2 were isolated from Jamaican patients. No dengue isolates were obtained from Dominica or Trinidad, although IgM capture ELISA test results suggested current or recent exposure to dengue virus in one Dominican patient. Improved surveillance for dengue could lead to detection of the emergence of new dengue serotypes, or detection of increased virus activity. Using surveillance data to target efforts to control the Aedes aegypti mosquito vector in areas where infection cases reside could reduce the impact of dengue disease in the Caribbean. (AU)
