La finalidad del mismo es contribuir a planificar estrategias de prevenci贸n y control basadas en la evidencia, para asegurar que la informaci贸n cient铆fica relevante sobre protecci贸n y tratamiento de la leishmaniasis circule, en el 谩rea de estudio, por redes sociales pertinentes.This paper describes first results of a research project about social representations and practices in a risk group of Tegumentary Leishmaniasis (Argentina NE, Misiones province). Main objective of this field research is to contribute for based on evidence prevention planning, trying to ensure disease scientific information about prevention and treatment flow by proper social nets in the area under studying

    Epidemiological aspects of cutaneous leishmaniasis in the Iguaz煤 falls area of Argentina

    Over the last three decades the incidence of American cutaneous leishmaniasis (ACL) has increased sharply in Argentina and throughout the world. In the Iguaz煤 Falls area, on the border between Brazil and Paraguay, the incidence of human ACL has risen since 2004. Most of the 36 cases of human ACL reported until 2005 have involved males over 15 years old (75%) infected during deforestation to establish individual farms. Captures carried out in primary forest, periurban areas, and deforested land sites yielded 18,438 sand flies belonging to 13 species; the most prevalent species were Lutzomyia (Nyssomyia) whitmani (87.4%) and Lutzomyia (Mygonemyia.) migonei (7.6%). Cluster analysis was used to group traps according to species and abundance of sand flies. The group of traps located in recently deforested places, in pig and chicken dwellings of houses where ACL cases had been reported in the past, and at one house with an active ACL case, had the highest abundance of Lu. whitmani and Lu. whitmani + Lu. migonei as well as the highest ratio of Lu. whitmani/Lu. migonei. Leishmania sp. infections, both in Lu. whitmani, in Lu. quinquefer, and in smears from human cases were detected by DNA kinetoplast amplification using a generic PCR protocol. The risk of ACL outbreak in the Iguaz煤 Falls area is still associated with economic and leisure activities in primary-secondary forest, including deforestation, rural settlements, fishing, hunting, and ecotourism. In addition, the risk of periurban transmission seems likely, and this is discussed within the framework of surveillance and prevention strategies. 漏 2008 Elsevier B.V.

    Aedes aegypti is the main domestic vector of the dengue virus. Control measures to prevent dengue transmission focus on the treatment and elimination of this vector's oviposition sites. There is limited biological information on Ae. aegypti in Argentina. The aim of this study was to characterize Ae. aegypti oviposition sites in the city of Puerto Iguaz煤, Argentina. We surveyed an area covering nine neighborhoods in 2005. We identified 191 premises as positive for Ae. aegypti, giving a general house index of 9.6%. Premises classified as residential and vacant lots presented the highest number of infested premises, with 9% and 22% respectively. The total number of surveyed containers was 29,600. The overall container index (CI) was 1.1. The most frequently infested containers were water tanks (CI = 37). These preliminary results suggest that vacant lots and water tanks provide suitable breeding areas and environmental conditions, improving the chances of Ae. aegypti survival in Puerto Iguaz煤.<br>El mosquito Aedes aegypti es el vector dom茅stico m谩s importante del virus dengue. Existe limitada informaci贸n de la biolog铆a del Ae. aegypti en Argentina. Con el fin de identificar los sitios de oviposici贸n de Ae. aegypti en la ciudad de Puerto Iguaz煤, Argentina, se estudi贸 un 谩rea compuesta por nueve barrios durante el a帽o 2005. Se registraron 191 inmuebles positivos sobre un total de 1.977 inspeccionados. La categor铆a "vivienda" fue la m谩s numerosa, y donde se encontr贸 el mayor n煤mero de inmuebles positivos, el porcentaje de infestaci贸n fue del 9%. La categor铆a "bald铆o" registr贸 un porcentaje de infestaci贸n de 22%. El n煤mero total de recipientes potenciales inspeccionados fue de 29.600 y 1,1% de los recipientes resultaron positivos. Por otro lado, la mayor proporci贸n de criaderos positivos perteneci贸 a la categor铆a tanques de altura (37%). Estos resultados preliminares sugieren que sitios bald铆os y tanques de altura proveen posibles 谩reas de reproducci贸n y condiciones ambientales que mejoran las posibilidades de supervivencia de Ae. aegypti
