ABSTRACT
INTRODUCTION:
Brazil has a high number of HTLV-1/2 infections which are unequally distributed in the country. Most prevalence studies have focused on specific populations, such as blood donors and pregnant women. Some areas, for example the state of Bahia, have robust information about HTLV-1/2 infection, however there is no information available about this infection in the general population of Vitória, Espírito Santo, Brazil.OBJECTIVE:
To determine the prevalence of HTLV-1/2 infection in adults from the municipality of Vitoria, ES.METHODS:
A cross sectional study was performed from September 2010 to December 2011, in individuals of both sexes, aged 18 or older living in Vitória-ES. Venous blood samples were collected and tested for anti-HTLV-1/2 antibodies by chemiluminescent immunoassay (CMIA). Individuals with CMIA reactive results were submitted to a new blood collection for retesting by CMIA, followed by PCR to confirm infection and discriminate the viral type.RESULTS:
From 1502 tested samples, eight were reactive in CMIA and all were confirmed by PCR. Therefore, the prevalence of HTLV-1/2 was 0.53% (8/1502, 95% CI 0.2-1.0%). The infection rate was 0.7% in men (5/711, 95% CI 0.17-1.51%), and 0.38% in women (3/791, 95% CI 0-0.81%).CONCLUSIONS:
The prevalence of HTLV-1/2 infection was 0.53% (8/1502; 95% CI 0.2-0.9%). Confirmatory test using real-time PCR (qPCR) identified seven individuals positive for HTLV-1 and one for HTLV-2. Considering the risk of infected individuals to develop high morbidity and mortality diseases, it would be important to implement public health policies aimed at stopping transmission of these viruses in this municipality.Palavras-chave
