A large number of arthropod-borne viruses are endemic to East Africa. As a part of the process of undertaking a systematic characterization of the mosquito fauna of Uganda, we examined mosquitoes collected from 2008 through early 2012 for known and novel viruses. In all, 8,288 mosquito pools containing 157,554 mosquitoes were tested. Twenty-nine isolations of 11 different viruses were made from mosquitoes of nine distinct species and from pools identified only to genus Culex. Identified viruses were from family Togaviridae, alphaviruses Sindbis and Babanki viruses; family Rhabdoviridae, hapaviruses Mossuril and Kamese viruses; family Flaviviridae, flaviviruses West Nile and Usutu viruses; family Phenuiviridae, phlebovirus Arumowot virus; and family Peribunyaviridae, orthobunyaviruses Witwatersrand, Pongola, and Germiston viruses. In addition, a novel orthobunyavirus, provisionally named Mburo virus, was isolated from Coquillettidia metallica (Theobald). This is the first report of Babanki, Arumowot, and Mossuril virus isolation from Uganda.
