an epidemiologic and serologic study of arboviruses in lake rudolf basin.	an epidemiologic and serologic study of arboviruses was done in 1972 in the basin of lake rudolf. the main object of this study was to demarcate the southern limit of the yellow fever epidemic which occurred from 1959 to 1962 in southern sudan and ethiopia. other purposes were to contribute to the inventory of arboviruses and their distribution in this region. the ethnic groups were studied: the nyangatom and the dassanetch in ethiopia and the turkana in northern kenya. the results of tests on s ...	1975	242102
first field evidence for natural vertical transmission of west nile virus in culex univittatus complex mosquitoes from rift valley province, kenya.	west nile virus is a mosquito borne flavivirus endemic over a large geographic area including africa, asia, and the middle east. although the virus generally causes a mild, self-limiting febrile illness in humans, it has sporadically caused central nervous system infections during epidemics. an isolate of west nile virus was obtained from a pool of four male culex univittatus complex mosquitoes while we were conducting an investigation of rift valley fever along the kenya-uganda border in februa ...	2000	10813479
mosquito species abundance and diversity in malindi, kenya and their potential implication in pathogen transmission.	mosquitoes (diptera: culicidae) are important vectors of human disease-causing pathogens. mosquitoes are found both in rural and urban areas. deteriorating infrastructure, poor access to health, water and sanitation services, increasing population density, and widespread poverty contribute to conditions that modify the environment, which directly influences the risk of disease within the urban and peri-urban ecosystem. the objective of this study was to evaluate the mosquito vector abundance and ...	2011	21626425
arbovirus prevalence in mosquitoes, kenya.	few studies have investigated the many mosquito species that harbor arboviruses in kenya. during the 2006-2007 rift valley fever outbreak in north eastern province, kenya, exophilic mosquitoes were collected from homesteads within 2 affected areas: gumarey (rural) and sogan-godud (urban). mosquitoes (n = 920) were pooled by trap location and tested for rift valley fever virus and west nile virus. the most common mosquitoes trapped belonged to the genus culex (75%). of 105 mosquito pools tested, ...	2011	21291594
