Comparative Studies on Endemic Areas of Bancroftian Filariasis in Greater Recife, Brazil. Cad. Saúde Públ., Rio de Janeiro, 10 (supplement 2): [301][302][303][304][305][306][307][308][309] 1994. Two districts in Recife (Santo Amaro and Campo Grande) and two districts in Olinda (Sapucaia and Salgadinho), were selected for a comparative study of bancroftian filariasis in Greater Recife. Selection parameters included similar socio-economic, demographic, and endemic levels of lymphatic filariasis. In the districts studied, streets were chosen randomly. These clusters consisted of 110 people each. A population sample was stratified by sex and age: 0-4, 5-9, 10-14, 15-19, 20-29, 30-39, 40-49, 50-59 and 60 years old and over. The parasitological data were obtained by measuring thick blood smears (60Fl), collected from 8:00 to 12:00 PM and processed and stained with hematoxylin. The data were described in tables, and logarithimic expression graphics were used to analyze parasitic densities. In general, Recife showed a prevalence of 13.5%, and Olinda 12.3%. Mean parasitic densities were 41 and 70 microfilariae/60Fl (mf/60Fl), respectively. Higher microfilaremic rates were observed in Recife for the 20-29-year age bracket and in Olinda in the 30-39-year bracket. The authors concluded that the disease has returned to former endemic levels, and the data described call for a reevaluation of control campaigns carried out by the Brazilian National Health Foundation, since the endemic has already reached serious proportions. Key words: Filariasis; Wuchereria bancrofti; Epidemiology INTRODUÇÃOA filariose corresponde a um grupo de doenças associadas a helmintos do filo Nematoda, superfamília Filarioidea. No Brasil encontram se as espécies Wuchereria, Onchocerca, e Mansonella, causando variado espectro clinicopatológico. A denominação "filariose linfática" está relacionada a três parasitos, Wuchereria bancrofti, Brugia timori, e Brugia malayi.Embora a filariose bancroftiana possa ocasionar considerável grau de morbidade, relacionado às formas agudas e crônicas da patologia, a mortalidade é quase nula.Segundo estimativa da Organização Mundial da Saúde (1992), três bilhões de pessoas vivem em países endêmicos, 75 milhões estão infectadas, entre as quais, 72 milhões por W. bancrofti. A distribuição geográfica da infecção/doença pela W. bancrofti atinge países como China, Indonésia, Índia e países africanos (WHO, 1992).A filariose teria chegado ao Brasil pelo tráfico de escravos; entretanto, os primeiros
