Seroepidemiologic Study of Oropouche Virus, Amazonas State, Brazil, 2015-2016. [PDF]

Emerg Infect Dis
We conducted a cross-sectional serosurvey for Oropouche virus (OROV) among residents of Amazonas State, Brazil, during 2015–2016. We detected OROV neutralizing antibodies in 85/814 (10.4%) participants; seroprevalence was higher in Manaus (49/440 [11.1%]

Virological findings in a case of travel-associated Oropouche virus (OROV) infection imported to Italy, June 2024

Travel Medicine and Infectious Disease
Here we report the acute and post-acute virological findings in a OROV infected traveller returning to Italy from Cuba. Testing multiple specimen types and the prolonged detection of OROV RNA in whole blood and urine samples extend the possibility of cases confirmation through direct diagnosis even in convalescence-phase of infection.

Novel Reassortants of Oropouche Virus (OROV) Are Causing Maternal–Fetal Infection During Pregnancy, Stillbirth, Congenital Microcephaly and Malformation Syndromes

Genes
Oropouche virus (OROV) is an orthobunyavirus endemic in the Brazilian Amazon that has caused numerous outbreaks of febrile disease since its discovery in 1955. During 2024, Oropouche fever spread from the endemic regions of Brazil into non-endemic areas and other Latin American and Caribbean countries, resulting in 13,014 confirmed infections ...
