Description
Summary:During March 1994 cases of a exanthematic acute disease were reported in the municipalities of Itagemirim, Eunápolis and Belmonte, state of Bahia. Dengue fever was confirmed by serology (MAC-ELISA) and by dengue virus type 2 isolation, genotype Jamaica. Signs and symptoms of classic dengue fever were observed with a high percentual of rash (73.8%) and pruritus (50.5%). Major haemorrhagic manifestations were unfrequent and only bleeding gum was reported. Dengue virus activity spreaded rapidly to important tourism counties like Porto Seguro, Ilhéus, Santa Cruz de Cabrália, Prado, Alcobaça and others, representing a risk for the spreading of dengue virus into the country and abroad. Em março de 1994, casos de uma doença exantemática foram notificados nos municípios de Itagimirim, Eunápolis e Belmonte, sul da Bahia. Infecção por dengue foi confirmada por sorologia (MAC-ELISA) e pelo isolamento de virus dengue tipo 2 (genotipo Jamaica). Sinais e sintomas de dengue clássico foram observados com um alto percentual de exantema (73,8%) e prurido (50,5%). Manifestações hemorrágicas não foram importantes e apenas casos de gengivorragia foram descritos. A atividade dos virus dengue espalhou-se rapidamente para importantes áreas de turismo da região, tais como Porto Seguro, Ilhéus, Santa Cruz de Cabrália, Prado, Alcobaça e outros, representando um risco da dispersão do virus para outras regiões do país e exterior.
