The past and present distribution of Bancroftian filariasis in Brazil is reviewed. Parasitological and entomological surveys were conducted between 1951 and 1958, the autochthonous transmission of Wuchereria bancrofti having been found only in 11 places in the country as follows, with the corresponding prevalences; Ponta Grossa (SC), 14.5% Belém (PA), 9.8%; Barra de Laguna (SC), 9.4%; Recife (PE), 6.9%; Castro Alves (BA), 5.9%; Florianópolis (SC), 1.4%; São Luis (MA), 0.6%; Salvador (BA), 0.4%; Maceió (AL), 0.3%; Manaus (AM). 0.2% and Porto Alegre (RS), 0.1%. The distribution of infection was urban and focal, occurring mainly along the coast. Control measures carried out against filariasis achieved considerable success, reducing infection and transmission, only Belém and Recife being considered endemic areas. Recent studies show the active transmission of filariasis with higher prevalences than those observed in the past, in Maceió, considered to be free from infection, and in Recife. The knowledge of the present status of Bancroftian filariasis in Brazil is important as baseline information, because it will allow for the establishment of control measures by Public Health organizations.
本文回顾了班氏丝虫病在巴西的过去和现在的分布情况。在1951年至1958年期间进行了寄生虫学和昆虫学调查，发现班氏吴策线虫的本土传播仅在该国的11个地方出现，具体情况如下，以及相应的流行率；大港市（圣卡塔琳娜州），14.5%；贝伦市（帕拉州），9.8%；拉古纳巴拉市（圣卡塔琳娜州），9.4%；累西腓市（伯南布哥州），6.9%；卡斯特罗·阿尔维斯市（巴伊亚州），5.9%；弗洛里亚诺波利斯市（圣卡塔琳娜州），1.4%；圣路易斯市（马亚纳州），0.6%；萨尔瓦多市（巴伊亚州），0.4%；马塞约市（阿拉戈斯州），0.3%；马瑙斯市（亚马逊州），0.2%和阿雷格里港市（南里奥格兰德州），0.1%。感染分布呈城市性和局部性，主要发生在沿海地区。针对丝虫病采取控制措施取得了显著成效，减少了感染和传播，仅贝伦和累西腓被视为流行地区。最近的研究表明，在被认为无感染的马塞约市以及累西腓市，丝虫病有活跃传播，流行率高于过去观察到的水平。了解巴西班氏丝虫病的现状作为基线信息很重要，因为这将有助于公共卫生组织制定控制措施。
