This study aimed to determine the prevalence of HTLV-1 infection among remnant black quilombo communities in Central Brazil. A total of 1,837 individuals were evaluated, among whom nine were HTLV-1/2 seropositive according to ELISA. All of them were positive for HTLV-1 by means of Western blot and/or PCR, thus resulting in a prevalence of 0.5% (95% CI: 0.2-1.0). The HTLV-1 infected individuals ranged in age from 11 to 82 years. The majority of them were females. Regarding risk characteristics, histories of breastfeeding, blood transfusion, multiple sexual partners and sexually transmitted diseases were reported by these individuals. The findings from this study indicate the importance of identifying HTLV-1 infected individuals, as a strategy for infection control and prevention in these remnant quilombos.
本研究旨在确定巴西中部黑人逃亡黑奴聚居地残余社区中人类嗜T淋巴细胞病毒1型（HTLV-1）感染的流行情况。共对1837人进行了评估，其中根据酶联免疫吸附测定法（ELISA）有9人HTLV-1/2血清学呈阳性。通过蛋白质印迹法和/或聚合酶链反应（PCR）检测，他们均为HTLV-1阳性，因此患病率为0.5%（95%置信区间：0.2-1.0）。HTLV-1感染个体的年龄在11岁至82岁之间。其中大多数为女性。关于风险特征，这些个体报告了母乳喂养、输血、多个性伴侣和性传播疾病史。本研究结果表明识别HTLV-1感染个体的重要性，这是在这些残余黑奴聚居地进行感染控制和预防的一项策略。
