Resumo: | A serological survey for hemagglutination - inhibition antibodies to arbovirus was carried out on 516 residents of the rural and urban zones of the Ribeira Valley, Brazil, a largely forested area where there recently occurred an encephalitis epidemic attributed to Flavivirus Rocio. It was discovered that 24.2% of the sample population presented HI antibodies (11.2% against Alphavirus, 13.2% against Flavivirus, 4.6% against the Caraparu virus and 0.8% against other arboviruses). Neutralizing antibodies for Eastern equine encephalitis, St. Louis encephalitis and yellow fever virus were detected in some of the people, not vaccinated against yellow fever, who have always lived in the region. These last two viruses have never before been isolated in the area. The characteristics of people who presented antibodies suggest that the transmission of arboviruses has been going on for a long time, in and outside the forested area, in at least nine districts of the region. Men, and especially fishermen, among other professions, who generally work in the evening and at night, present the highest risk of infection. |

Foi realizado inquérito sorológico para pesquisa de anticorpos inibidores de hemaglutinaçãc de arbovírus em 516 moradores das zonas urbana e rural da região do Vale do Ribeira, Brasil, área extensamente coberta de florestas onde ocorreu recentemente uma epidemia de encefalite atribuída ao Flavivirus Rocio. Verificou-se que 24,2% destas pessoas tinham anticorpos IH para um ou mais arbovírus (11,2% para Alphavirus; 13,2% para Flavivirus; 4,6% para o Bunyavirus Caraparu e 0,8% para outros arbovírus). Alguns dos investigados, sem antecedente de vacinação contra febre amarela, apresentaram anticorpos neutralizantes para o vírus da encefalite equina do Leste, St. Louis e da febre amarela, os dois últimos ainda não isolados na região. A análise das características dos indivíduos com sorologia positiva sugeria que a transmissão de arboviroses não era fato recente e estava se fazendo em pelo menos 9 municípios da área, não só no ambiente silvestre como fora do mesmo. Os indivíduos de sexo masculino e entre estes os que trabalham em pesca, em geral no período vespertino e noturno, apresentaram maior risco à infecções arbovíricas. Universidade de São Paulo.
