Presently, there are no data available on the endemicity of tick- and louse-borne relapsing fever spirochetes in Kenya. Here, we present data of a retrospective study on the seroprevalence of louse-borne relapsing fever (LBRF) in northern Kenya.
METHODS: A novel immunoassay, recently established for the diagnosis of LBRF was utilized to screen 2005 blood samples collected from individuals with fever without a source in Turkana County, Kenya between May 2009 and November 2010 for anti-LBRF antibodies.
RESULTS: Out of the 2005 sera analyzed, 287 samples (14.3 %) were considered anti-LBRF IgG positive. Subsequent analyses revealed that 87 out of 152 sera randomly selected from these 2005 samples were tested positive (57.2 %) for anti-LBRF IgM antibodies. Most of the IgG and IgM positive samples were from individuals living in northern regions of Turkana County.
CONCLUSIONS: Our serological finding provides strong evidence for the occurrence of LBRF in Kenya.
