Título: Laboratory diagnosis of yellow fever infections in humans, alouatta monkeys and haemagogus mosquitoes in Trinidad, 1978-1980

Resumo: The yellow fever epidemic in Trinidad began with an epizootic in alouatta monkeys in November, 1978. Activity was detected by virus isolation from Alouatta monkeys and from Haemagogus mosquitoes between this date and July 1980. First reports of monkey deaths centered around the Guayaguayare forests of South Trinidad, following which the epizootic spread west to the Moruga area, and north through the Biche Forest reserve, eventually reaching the north-west Chaguaramas peninsula. Surveillance of febrile persons attending clinics and hospitals was intensified and 18 confirmed cases were identified, from 14 of whom yellow fever virus was isolated. In four cases, diagnoses were made on the basis of liver pathology only. Paired sera were obtained from 10 of 11 persons who survived, and in each case serological conversions were obtained by haemagglutination inhibition and mouse neutralization tests. Yellow Fever virus was isolated from 16 of 32 Alouatta monkeys and from 19 of 174 pools of Haemagogus mosquitoes. Two systems were used for virus isolation: the Aedes cell line AP-61 and suckling mice. The former proved to be more sensitive, detecting virus in 11.7 percent of 725 specimens inoculated whereas suckling mice detected virus in 7.9 percent of 724 specimens. In 11 instances virus was detected in an animal or mosquito pool by AP-61 but not initially by mouse inoculation whereas the converse was true in only one case (AU)

Título: Monitoring of Alouatta monkeys as an early warning system in yellow fever surveillance
Fonte: In: Tikasingh, Elisha S. Studies on the natural history of yellow fever in Trinidad. Port of Spain, Caribbean Epidemiology Centre, 1991. p.59-62, tables. (CAREC Monograph Series, 1).
Idioma: En.
Resumo: An epizootic of yellow fever occurred in Alouatta monkeys in November 1978. An intensive surveillance programme was initiated to locate sick and dying monkeys in the forests of Trinidad. Thirty Alouatta (red howler)monkeys were collected and examined for yellow fever virus. Sixteen of the monkeys were positive for the virus and these came from south-east, east, and north-west Trinidad (AU)

Título: Surveillance for Alouatta monkeys in the forests of Trinidad, 1988-1989

Idioma: En.
Resumo: A continuous surveillance programme for the presence of the red howler monkeys (Alouatta sp.) in the forests of Trinidad was initiated following an epizootic of yellow fever in these monkeys in 1978. This paper gives the result of the programme from 1986 to 1989 (AU)
