Oropouche virus detection in saliva and urine

Oropouche virus (OROV) is an arthropod-borne virus of the Peribunyaviridae family, transmitted to humans primarily by Culicoides paraensis. It is one of the main arboviruses that infect humans in Brazil, mainly in the Amazon region. We report the OROV detection in the saliva and urine five days after the symptoms onset. Results were further confirmed by nucleotide sequencing and phylogenetic analysis. To our knowledge, this is the first report that OROV may be detected in the saliva and urine of infected patients. In addition, our results may contribute to the current knowledge regarding the natural history of Oropouche fever.

Complete genome of a Measles virus from Roraima state, Brazil

Measles is a human infectious disease of global concern caused by the measles virus. In this study, we report the complete genome sequencing of one measles isolate, genotype D8, obtained in Boa Vista city, the capital of the Roraima State, Brazil, directly from the urine sample. Phylogenetics reconstruction grouped the genome described in this study with samples from Australia, Italy, United Kingdom, and the USA. To our knowledge, this is the first complete genome of a wild-type measles virus from Latin America. Therefore, the present data strengthens the current knowledge about the molecular epidemiology of measles worldwide.\n\nSponsorshipsCNPq / CAPES / MS-DECIT / Fiocruz
