Biological transmission of Oropouche (ORO) virus by (Goeldi) has been successfully demonstrated in the laboratory. Adult , collected in an area where ORO virus was absent, were infected by feeding on viremic hamsters and then periodically exposed to susceptible hamsters at specific intervals post-infectious blood meal. These were capable of biological transmission of the virus 4–9 days post-feeding on viremic hamsters circulating 6.7–9.9 logSMLD/ml virus. Infection rates of 54% and 80% were found for assayed 7 days post-feeding. Virus transmission rates for these experiments were 83% and 25%, respectively. No evidence of mechanical transmission of ORO virus by was observed when interrupted feeding of on viremic hamsters was followed by feeding on susceptible hamsters.
