Lwande, O.W.Lutomiah, J.Obanda, V.Gakuya, F.Mutisya, J.Mulwa, F.Michuki, G.Chepkorir, E.Fischer, A.Venter, M.Sang, R.[Isolation of tick and mosquito-borne arboviruses from ticks sampled from livestock and wild animal hosts in Ijara district, Kenya]Isolation of tick and mosquito-borne arboviruses from ticks sampled from livestock and wild animal hosts in Ijara district, Kenya

Diagnostic methods allowing for rapid identification of pathogens are crucial for controlling and preventing dissemination after disease outbreaks as well as for use in surveillance programs. For arboviruses, detection of the presence of virus in their arthropod hosts is important for monitoring ...


Mwaengo, D.Lorenzo, G.Iglesias, J.Warigia, M.Sang, R.Bishop, Richard P.Brun, A.[Detection and identification of Rift Valley fever virus in mosquito vectors by quantitative real-time PCR]Detection and identification of Rift Valley fever virus in mosquito vectors by quantitative real-time PCR

An outbreak of Rift Valley fever (RVF) occurred in Kenya during November 2006 through March 2007. We characterized the magnitude of the outbreak through disease surveillance and serosurveys, and investigated contributing factors to enhance strategies for forecasting to prevent or minimize the imp...

Rift Valley fever (RVF) is a mosquito-borne viral zoonosis that is found in most regions of sub-Saharan Africa, and it affects humans, livestock, and some wild ungulates. Outbreaks are precipitated by an abundance of mosquito vectors associated with heavy persistent rainfall with flooding. We det...

Background West Nile fever virus is a zoonotic arboviral infection maintained in a sylvatic cycle involving mosquito vectors and birds. It is one the arboviruses whose geographical range is expanding because of climate and land use changes that enhance the densities of mosquitoes and promote mosq...

In December 2006, Rift Valley fever (RVF) was diagnosed in humans in Garissa Hospital, Kenya and an outbreak reported affecting 11 districts. Entomologic surveillance was performed in four districts to determine the epidemic/epizootic vectors of RVF virus (RVFV). Approximately 297,000 mosquitoes ...
