Free-ranging non-human primates (NHP) can live in anthropized areas or urban environments in close contact with human populations. This condition can enable the emergence and transmission of high-impact zoonotic pathogens. For the first time, we detected a coinfection of the yellow fever (YF) virus with Toxoplasma gondii in a free-ranging NHP in a...

Despite the considerable morbidity and mortality of Yellow fever virus (YFV) infections in Brazil, as well as its widespread presence in non-human primate host, our understanding of disease outbreaks is hampered by limited viral genomic data. Determining the timing and spatial corridors of YFV spread, as well as the geographic hotspots that link th...

The early detection and diagnosis of deaths in free-ranging non-human primates (NHPs) are key points for the surveillance of Yellow Fever (YF) in Brazil. The histopathological identification of infectious diseases remains very useful and reliable in the screening and detection of emerging zoonotic diseases such as YF. We surveyed data records and l...

In June 2019, a horse with neurological disorder was diagnosed with West Nile virus (WNV) in Boa Viagem, a municipality in the state of Ceará, northeast Brazil. A multi-institutional task force coordinated by the Brazilian Ministry of Health was deployed to the area for case investigation. A total of 513 biological samples from 78 humans, 157 domes...

The Information System on Wildlife Health (SISS-Geo) is based on citizen science and the use of mobile technologies, producing data and georeferenced alerts in real time for society, public health professionals, and conservation managers. From 2014 to 2020, the system recorded 4,909 non-human primates (NHP) in 23 states of Brazil. Joint action by t...

Shrinking natural habitats exposes some non-human primates to the risk of accidents associated with electrical transmission lines. We examined dead marmosets (Callithrix penicillata) collected in the region from January 2015 to April 2018 to determine the animals’ cause of death and for electrocuted animals we examined the locations the animals had...

Objective: to describe and analyze the change in the epidemiological profile of sylvatic yellow fever – whose cases began to occur outside the Amazon region, in Brazil – from 1999, when the detection of the virus in primates has led to the timely implementation of new surveillance measures. Methodology: this study is a descriptive analysis of epizo...
