Abstract
Rabies transmitted by sylvatic populations has become an increasing concern in Brazil. A total of 113 participants with a history of contact with sylvatic populations were interviewed in 27 municipalities of Ceará State in northeast Brazil. Questionnaires included questions on knowledge, attitudes and practices (KAP) regarding sylvatic rabies. Most of the respondents (92%) knew about rabies and confirmed at least one species that transmitted the disease (79.6%). Of these respondents, 69% mentioned monkeys, and 67.2% mentioned dogs. However, 16% of the respondents listed an incorrect species. In general, knowledge on the symptoms and signs and on prevention measures was weak. The majority raised pets (93.8%), most commonly dogs and cats, and, of all the pets, 85.7% were claimed to be vaccinated against rabies. A total of 67.3% reported the appearance of free-living wild animals around their houses, mostly marmosets and wild canids; 18.3% reported that sylvatic populations had attacked animals or humans. Seventy-three percent had raised or still were raising wild animals as pets, mostly capuchin monkeys (79.5%) and marmosets (24.1%). This is the first KAP study on sylvatic rabies in Brazil. The data indicate important knowledge gaps and risk behavior within a high-risk population. There is a need for strengthening and improving sylvatic rabies surveillance and control, combined with the intensification of education and information campaigns.Entities:

Figure 2Animals or categories of animals reported by respondents to be rabies virus transmitting animals. Others: snake (0.9%), parrot (0.9%), jaguar (0.9%), goat (0.9%), opossum (0.1%).
Figure 3Modes of transmission for rabies, as reported by respondents (bites, scratches and bats were considered as correct answers). Contact means touching and/or feeding the animals; live together means that animals are leashed or kept in cages on the property.
Figure 4Symptoms of rabies, as reported by respondents. * Others: barking (0.9%), not drinking sufficiently (0.9%), stiff tail (0.9%), quivering (0.9%).
Figure 5Knowledge on prevention of rabies, as reported by respondents (vaccination of animals and avoiding contact with wild animals were considered as correct answers). Killing the animal was considered an incorrect answer; after an act of aggression, domestic animals (esp. dogs) should be observed for a defined period at a safe place (without the possibility of contact to other animals or to humans).
