Samples from sera and oral swabs from fifteen marmosets (Callithrix jacchus) and nine capuchin-monkeys (Sapajus libidinosus) captured in Ceara State in Brazil were tested for Zika virus. Samples were positive by Real time PCR and sequencing of the amplified product from a capuchin monkey showed 100% similarity to other ZIKV from South America. This is the first report on ZIKV detection among Neotropical primates.

To analyze the eco-epidemiologic aspects of Histoplasma capsulatum in Brazil, we tested 83 bats for this fungus. Although H. capsulatum was not isolated, Coccidioides posadasii was recovered from Carollia perspicillata bat lungs. Immunologic studies detected coccidioidal antibodies and antigens in Glossophaga soricina and Desmodus rotundus bats.

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.

Rabies is an endemic disease in Brazil, where it is considered a serious public health problem. Although the number of human and dog-transmitted cases has declined in recent decades, rabies in wildlife has emerged considerably. Among the sylvatic animals, wild canids have been considered important hosts of the rabies virus. We performed a retrospective study of reported cases of rabies in wild canids and human victims in Ceará state (Northeast Brazil) during 2003 to 2013. Information was provided by governmental laboratories involved in rabies detection and by the Ministry of Health. From January 2003 to December 2013, a total of 11 931 animal samples were examined for rabies. Positivity were detected in 438 samples (3.67%), of which 229 (52.28%) were domestic animals, 105 (23.97%) wild canids and 104 (23.74%) other wild animals (bats, marmosets and raccoons). Approximately 33% of wild canids surveyed (n = 317) were positive for rabies. During the studied period, a total of 1923 attacks on humans by wild canids were registered. Males (n = 1405) were more affected than females (n = 520; 72.98% versus 27.01%), and the median age of all cases was 36.5 years. Injuries to individuals up to 19 years old corresponded to approximately 30% (n = 565) of all cases. Most of the victims lived in rural areas (72.46%; n = 1395), and the majority showed bites (81.13%; n = 1677) or scratches (12.23%; n = 253). Injuries were considered profound (52.1%; n = 1003), superficial (40.91; n = 788) or multiple with severe laceration (6.98%; n = 134). Only 1300 (67.53%) victims were enrolled for the complete rabies post-exposure prophylaxis scheme. Data from the present study confirm that wild canids are important hosts of rabies virus in northeastern Brazil and jeopardize rabies control in this area. Local authorities should focus their efforts in education of health professionals. In addition, strategies should be formulated to preserve wildlife.
