AbstractAn inquiry about the cases of myiasis by Cochliomyia hominivorax larvae in cats presented to 227 veterinary establishments of the Northern, Southern, and Western Zones of Rio de Janeiro municipality in 2000 was performed, to identify predisposing factors and to contribute to the comprehension of the epidemiological features of this parasitic disease. In one hundred and fifty two establishments, at least one case of myiasis by C. hominivorax larvae in cats was presented, and dogs were most infested than cats. Incidence was higher in hot weather months or periods of the year: January, February, November, and December. Adult, dark and short-haired, intact males, and mixed-breeding cats were the most affected. Because myiasis by C. hominivorax larvae are often in Rio de Janeiro City, as concluded in this inquiry, and it is not necessary to report the cases to authorities, a lot of clinicians did not consider it as a disease of great importance. Preventive programs against screwworm infestation should be developed according to identified predisposing factors, such as phenotypic features of infested animals (breed, hair color, hair size, sex, and age) and months of highest incidence, when programs should be intensified. Pet owners should be warned by veterinary clinicians about harm caused by myiasis and should receive directions about preventive rules, including maintenance of environment hygiene and avoidance of more common myiasis causes.
