OBJECTIVE: To determine the seroprevalence of human T-cell leukaemia virus (HTLV) type I and predictive variables in Curaçao.
DESIGN: Descriptive.
SETTING: St. Elisabeth Hospital, Curaçao.
METHODS: A total of 2531 sera were randomly collected from a total population of approximately 145,000 over a period of three months (of seven the sex was not known). An initial ELISA test was performed to detect anti-HTLV-I antibodies. If this test was positive an ELISA re-test (in duplicate) was performed. If one of these re-tests was found positive a western blot confirmation test was performed. The association with age, sex, social class and history of syphilis were analysed with multiple logistic regression models and adjusted for confounding.
RESULTS: The estimated prevalence of HTLV-I was 1.9% (49/2524). No significant sex differences were observed (odds ratio (OR): 1.13; 95% confidence interval (95% CI): 0.62-2.05). Increasing age (p for trend = 0.0003) and lower social class (OR: 1.86; 95% CI: 1.03-3.38) were important predictive factors for HTLV-I infection. Members of the lower social classes and persons 50 years or older were at relatively high risk (OR: 3.91; 95% CI: 2.21-6.94).
CONCLUSION: HTLV-I infection is endemic in the island of Curaçao, as in other Caribbean islands. The estimated prevalence is 1.9%. Age and lower social class were important predictive factors for HTLV-I infection.
