Article Synopsis
- Oropouche virus (OROV) is an arbovirus that has spread beyond its usual Amazon basin habitat, with a significant outbreak occurring in the Brazilian Amazon during 2023-24, leading to cases in other Latin American countries.
- A genomic and epidemiological study from January 2023 to July 2024 showed a higher incidence of OROV in smaller municipalities, and a correlation between agricultural area sizes, particularly banana and cassava plantations, and the number of OROV cases.
- Phylogenetic analysis indicated multiple exportation events of a new reassortant lineage of OROV from Amazon regions to other parts of Brazil occurred between January and March 2024.
Norovirus is a major cause of acute diarrheal disease (ADD) outbreaks worldwide. In the present study, we investigated an ADD outbreak caused by norovirus in several municipalities of Santa Catarina state during the summer season, southern Brazil in 2023. As of the 10th epidemiological week of 2023, approximately 87 000 ADD cases were reported, with the capital, Florianópolis, recording the highest number of cases throughout the weeks.
