[Myiasis associated with some socioeconomic factors in five urban areas of the State of Rio de Janeiro].

This was a descriptive epidemiological study with the aim of evaluating the occurrence of human myiasis in urban areas of four municipalities in the State of Rio de Janeiro. Seventy-one patients who spontaneously sought attendance at primary healthcare units between October 1999 and October 2003 were examined. The disease was more prevalent among adults, including in individuals more than 51 years old (42.3%), and among children less than 10 years old (33.8%). From all the cases studied, 62% were of low socioeconomic level; 60.6% were male; and 33.8% of the infested individuals were unemployed. In the cases analyzed, the bioagent species were Cochliomyia hominivorax (Coquerel, 1858), Dermatobia hominis (Linnaeus Jr, 1781) and Cochliomyia macellaria (Fabricius, 1775). The results point towards an association between the disease and the patients living and hygiene conditions. This indicates the need for more specific healthcare among more vulnerable groups.
