“…quinquefasciatus and W. bancrofti from Recife, resulted in a vector competence of 53% (based on Janousek & Lowrie 1989). This vector competence is among the highest reported in the literature and may account, at least, in part, for high mf rate in Recife (14.7%) (Maciel et al 1996).…”

“…In 1952, Azevedo and Dobbin registered lymphatic filariasis in a local district with microfilaraemia rate of about 9.7%. A recent survey, of several areas, has shown that W. bancrofti infection now has prevalence rates ranging from 0.64 to 14.95% (Maciel et al 1996). In addition to increasing incidence of lymphatic filariasis in some areas, the number of breeding places for Cx.…”

“…Vectors of dengue fever and yellow fever are able to exploit artificial sources of water such as water storage pots, tires, or old containers in garbage. Polluted wastewater also provides a suitable breeding environment for Culex mosquitoes that transmit lymphatic filariasis (199) and arboviruses such as SLE virus in the United States and Rift Valley fever virus in Africa (292). Meanwhile, ruralurban migration is credited with leading to a new pattern of infection referred to as urban schistosomiasis (329).…”

Global Change and Human Vulnerability to Vector-Borne Diseases

Global change includes climate change and climate variability, land use, water storage and irrigation, human population growth and urbanization, trade and travel, and chemical pollution. Impacts on vector-borne diseases, including malaria, dengue fever, infections by other arboviruses, schistosomiasis, trypanosomiasis, onchocerciasis, and leishmaniasis are reviewed. While climate change is global in nature and poses unknown future risks to humans and natural ecosystems, other local changes are occurring more rapidly on a global scale and are having significant effects on vector-borne diseases. History is invaluable as a pointer to future risks, but direct extrapolation is no longer possible because the climate is changing. Researchers are therefore embracing computer simulation models and global change scenarios to explore the risks. Credible ranking of the extent to which different vector-borne diseases will be affected awaits a rigorous analysis. Adaptation to the changes is threatened by the ongoing loss of drugs and pesticides due to the selection of resistant strains of pathogens and vectors. The vulnerability of communities to the changes in impacts depends on their adaptive capacity, which requires both appropriate technology and responsive public health systems. The availability of resources in turn depends on social stability, economic wealth, and priority allocation of resources to public health

“…Albuquerque e col. 2 (1995), estudando duas outras áreas de Recife (bairros Coque e Mustardinha), encontraram prevalências de microfilarêmicos de 10,7% e 9,3%, respectivamente. Maciel e col. 17 (1996) Apesar do programa de controle da bancroftose, implementado em Maceió, cuja prevalência era 0,3% no passado 7 , ter se restringido somente ao tratamento dos parasitados diagnosticados na época, o Ministério da Saúde considerava a parasitose extinta na capital alagoana 19,38 . No entanto, em 1990, após o encontro de um paciente autóctone com linfangite retrógrada, uma das formas clínicas da filariose linfática foi levantada a hipótese da ocorrência, ainda hoje, da bancroftose em Maceió 10 .…”

Foi feita revisão dos estudos sobre a distribuição geográfica e prevalências da filariose linfática bancroftiana no Brasil. Entre 1951 a 1958 foram realizados inquéritos hemoscópicos e entomológicos no País, sendo a transmissão autóctone comprovada em apenas 11 Municípios: 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 Luís (MA), 0,6%; Salvador (BA), 0,4%; Maceió (AL), 0,3%; Manaus (AM), 0,2% e Porto Alegre (RS), 0,1%. A distribuição da parasitose era urbana e focal, principalmente em cidades litorâneas. As ações de controle implementadas levaram a uma apreciável queda nas taxas de microfilarêmicos sendo consideradas, a partir de então, áreas endêmicas para filariose linfática no Brasil somente as cidades de Belém e Recife. Estudos recentes mostram transmissão ativa da parasitose, com prevalências superiores às detectadas no passado, em Maceió, cujo foco era considerado extinto, e em Recife. O conhecimento da situação atual da bancroftose no Brasil é de fundamental importância para a implementação de ações de controle da endemia envolvendo o Ministério da Saúde e órgãos de saúde pública.
