Resumo Objetivo Descrever os casos de raiva humana no estado do Ceará, Brasil, no período 1970-2019. Métodos Estudo descritivo, sobre dados secundários da Secretaria da Saúde e do hospital de referência do Ceará. Resultados Dos 171 casos, 75,7% ocorreram em homens, 60,0% nas idades até 19 anos e 56,0% em áreas urbanas. O cão foi agente transmissor em 74,0% dos casos; sagui em, 16,7%; e morcego, em 7,3%. Entre 1970 e 1978, houve crescimento do número de casos (pelo Joinpoint Regression Program, percentual da mudança anual [APC] = 13,7 - IC95% 4,6;41,5); e entre 1978 e 2019, redução (APC = -6,7 - IC95% -8,8;-5,9). Houve redução da transmissão por cães (71 casos; último caso em 2010) e aumento relativo por mamíferos silvestres (5 casos a partir de 2005). Conclusão O estudo evidencia mudança na dinâmica da transmissão da raiva no período observado, com redução da transmissão por cão e incremento de casos por animais silvestres.
Introduction: Rabies is considered one of the most relevant public health problems owing to its high fatality rate and the high number of deaths worldwide. Methods: We included patients with human rabies who attended a reference hospital in the state of Ceará during 1976-2019. Results: Data were available for 63 out of 171 (36.8%) patients. Of these patients, 48 (76.2%) were attacked by dogs. In recent years, wild animals have been the most common aggressor species (marmosets and bats). Only 39 (70%) patients were initially correctly suspected with rabies. Bites were the most frequent exposure (56; 96%), most commonly on the hands (21; 42%) and the head (9; 18.4%). Only 14 (22%) patients had sought medical assistance before the onset of symptoms, and only one completed post-exposure prophylaxis. The most prevalent signs and symptoms included aggressiveness/irritability (50; 79.4%), fever (42; 66.7%), sore throat/ dysphagia (40; 63.5%), and myalgia (28; 44.4%). Hydrophobia was present in 17 patients (22.0%). Conclusions: Most cases of human rabies in Ceará occurred due to the failure to seek medical assistance and/or the failure of the health system in initiating early postexposure prophylaxis. There is a need for specific information and education campaigns focusing on the cycle of sylvatic rabies as well as prevention measures. Health professionals should undergo refresher training courses on the signs and symptoms of rabies and on the specific epidemiological features of the disease in Brazil.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
