Biting midges in the genus Culicoides act as vectors of arboviruses throughout the world and as vectors of filariasis in Latin America, the Caribbean, and parts of Africa. In particular, Culicoides paraensis is the predominant vector of the disease. In humans, it is transmitted primarily through the bite of the Culicoides paraensis midge. In the eastern half of the US where EHDV-6 has been repeatedly isolated from dead WTD during outbreaks, C. sonorensis is rare or absent, suggesting that other Culicoides species are involved with the transmission and maintenance of EHDV-6, as well as EHDV-1 and EHDV-2. The adults fly and copulate in swarms. … Oropouche fever causes symptoms similar to those of dengue with an incubation period of 4-8 days (range: 3-12 days). Local authorities are conducting epidemiologic investigations and strengthening vector control in response to the outbreak, the WHO said.

Culicoides imicola (Culicoides imicola Kieffer, former name C. pallidipennis Carter) is a species of Ceratopogonidae that transmits the bluetongue virus (BTV) and the African horse sickness virus. The global distribution of BTV infection has recently altered, perhaps driven in part by climatic influences on midge species resident in different regions. Based primarily on midge abundance, seasonal occurrence, and host preference, it has been suggested that C. debilipalpis, C. stellifer, C. obsoletus, C. paraensis, and C. spinosus warrant further investigation as potential vectors of EHDV and BTV to WTD in the southeastern US [33,37,39] and C. debilipalpis has been shown experimentally to support replication of EHDV-2 [22].
