Table

Possible vectors of Oropouche virus found in the United States and summary of laboratory and field data

Species Laboratory evidence Field data
Culicoides paraensis biting midge
 Experimental infection from human to hamster through Cu. paraensis biting midge (9); efficient vector in laboratory studies (9)
 Viral isolation from field collections during outbreaks in Para state, Brazil, 1978 (14); abundance correlated with higher seroprevalence in Para state, Brazil, 1975 (10)
Culex quinquefasciatus mosquito
 Experimental infection from hamster to hamster via Cx. quinquefasciatus mosquito (12); found to be inefficient vector (possibly due to midgut barrier) in 1 study (13) but was found to have a low level of efficiency in other studies (15,16)
 Viral Isolation from field collections in Para state, Brazil, 1961 and 1968 (10)
Culicoides sonorensis biting midge‡ Efficient vector in laboratory studies (15,16)) No viral isolations from field
