Epidemiologia da raiva humana no estado do Ceará, 1970 a 2019 / Epidemiología de la rabia humana en el estado de Ceará, Brasil, 1970 a 2019 / Epidemiology of human rabies in the state of Ceará, Brazil, 1970 to 2019

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.

Resultados: De los 171 casos, 75,7% ocurrió en hombres, el 60,0% en los 19 años y el 56,0% en áreas urbanas. El perro fue transmisor en 74,0%, el mono tití en 16,7% y el murciélago el 7,3%. Entre 1970 y 1978, hubo un aumento de casos (por el Joinpoint Regression Program, cambio porcentual anual [APC] = 13,7 - IC95% 4,6; 41,5), entre 1978 y 2019 una disminución (APC= -6,7 - IC95% -8,8; -5,9). Hubo una reducción de la transmisión por perros (71 casos, el último en 2010) y un aumento por mamíferos salvajes (5 casos, desde 2005). Conclusión: El estudio muestra un cambio en la dinámica de la transmisión de la rabia en los últimos años, con reducción de la transmisión por perros y aumento de casos por animales salvajes.

Objective: To describe cases of human rabies in Ceará State, Brazil between 1970 and 2019. Methods: This was a descriptive study using secondary data from the Ceará State Department of Health and the state reference hospital. Results: Of 171 cases, 75.7% occurred in males, 60.0% in <19-year-olds, and 56.0% in urban areas. Rabies was transmitted by dogs in 74.0% of cases, marmosets in 16.7% and bats in 7.3%. Between 1970 and 1978, there was an increase of cases (using the Joinpoint Regression Program, annual percentage change [APC] = 13.7 - 95%CI 4.6;41.5), while between 1978 and 2019 there was a decrease (APC = -6.7 - 95%CI -8.8;-5.9). There was a reduction in transmission by dogs (71 cases, last case in 2010) and an increase by sylvatic animals (5 cases since 2005). Conclusion: This study demonstrates changes in rabies transmission dynamics during the period studied, with a reduction in transmission by dogs and an increase of transmission by sylvatic animals.

Fatal anaphylaxis to Jaguajir rochae (Borelli, 1910) (scorpiones, buthidae) in Brazil: a case report

A 44-year-old healthy farmer, was stung by a scorpion on his right hand while preparing soil for planting in the Caatinga area (a large area in the north-east of Brazil characterized by semiarid scrub forest), in the Catarina Municipality countryside, Ceará State, Brazil. According to the reports of carers and family members, the patient initially reported mild pain at the site of the sting, but within a few minutes he developed malaise, pruritus in the body and throat, edema in the nostrils, and a dry mouth which led to looking for water to drink. It rapidly evolved into sphincter, urinary and fecal release, salivation and a convulsive episode with loss of the senses. He was dead on arrival at Catarina Municipality Hospital emergency department. The necroscopic report indicated suffocation due to glottal edema and acute lung edema as the "cause of death". The animal which caused the accident was under a rock that the patient was manipulating at the time of the incident, and has been identified by experts as Jaguajir rochae (Borelli, 1910) scorpion species, formerly synonymized Rhopalurus rochae. This is the first report of a fatality due to an allergic reaction to the venom of this species. This leads to the possibility that deaths caused by stings from other scorpion species may be due to anaphylaxis, whose symptoms in some situations may be confused with severe envenomation.
