Resumen
The presence of the human T-cell leukemia virus (HTLV) in Dominican blood donors and patients with tropical spastic paraparesis (TSP) was first detected in 1987. To define further the seroprevalence in the country, nearly 4,000 samples from high- and low-risk populations, as well as patients with neurological disease and with leukemia or lymphoma were tested for HTLV antibodies. A 1-2% seropositivity rate was found among the low-risk population, a 2-5% in the high-risk, and at least 87% in those with TSP. A few patients with malignancy also had antibodies to HTLV. An increase in seropositivity with age and a predominance of female seropositive individuals were found. Infectious virus was isolated from TSP patients, prostitutes, and family members of index patients. These data indicate the substantial level of HTLV infection in another Caribbean country and its relation to neurologic disease.
