ABSTRACT
The frequency of coinfection with Strongyloides stercoralis and human T-cell leukemia/lymphoma virus type 1 (HTML-1) was determined in 91 blood donors examined at the blood bank of a large hospital in Sao Paulo city, Brazil. As control group 61 individuals, not infected by HTLV-1, were submitted to the same techniques for the diagnosis of S. stercoralis infection. In HTLV-1 infected patients the frequency of S. stercoralis infection was 12.1 percent; on the other hand, the control group showed a frequency significantly lower of S. stercoralis infection (1.6 percent), suggesting that HTLV-1 patients shoud be considered as a high risk group for strongyloidiasis in Sao Paulo city.

A transmissao vertical do virus linfotropico para celulas T humanas tipo I (HTLV) ocorre principalmente atraves da amamentacao. Como um pequeno percentual de filhos de portadoras alimentados artificialmente e soropositivo, devem existir outras vias de transmissao vertical. A taxa de prevalencia de transmissao vertical no Japao varia de 15 por cento a 25 por cento. No Brasil, ainda nao existe nenhuma avaliacao desta forma de transmissao, no entanto, sabe-se que em Salvador-Bahia 0,7 por cento a 0,9 por cento das gestantes de classe socio-economica baixa sao portadoras

Distribution of human T-lymphotropic retrovirus type1 (HTLV-1) among Asian populations is reviewed from an anthropological point of view. The incidence of HTLV-1 infection among New Mongoloid and Indo-Aryan populations was quite low. There were no close phylogenetic relations among HTLV-1 endemic populations. HTLV-1 has been retained among peoples who have been isolated and/or depended on a primitive mode of living.

Este informe presenta el primer caso de SIDA, autóctono ocurrido en la República de Panamá, el cual fué diagnosticado en junio de 1985. Hasta octubre de 1985, se habían diagnosticado seis casos de SIDA, cinco de estos adquirieron la infección en el exterior, y uno, en la Rep. de Panamá. El caso autóctono no presentaba ninguna de las características típicas de los grupos de riesgo da SIDA. La entrevista epidemiológica de este caso y las subsiguientes investigaciones revelaron una red de transmisión que ha estado ocurriendo dentro de la República de Panamá desde 1979. Esta red incluye transmisión sexual de tipo homosexual y heterosexual en ambas direcciones, hemática transfusional y transplacentaria. Este informe pone en relieve la importancia trascedental de las entrevistas e investigaciones epidemiológicas, como intrumentos vitales para la identificación del problema del SIDA en el país y para el desarrollo de estrategias de control específico en cada país
