Abstract

Visceral Leishmaniasis also known as Kala-azar, is a tropical infectious disease caused by female sandflies. It affects the internal organs, usually the spleen, liver and bone marrow. Globally, an estimated 700 000 to 1 million new cases of visceral leishmaniasis occur annually. In Kenya, 4000 cases occur while 5 million people are at risk of infection. The purpose of the study was to evaluate risk factors for visceral Leishmaniasis. The study adopted a retrospective cohort design. The study used secondary data from 2890 visceral leishmaniasis patients enrolled at Marsabit County referral hospital from September 2015 to September 2019. Cox proportional hazard model was used to establish the relationship between the survival time of visceral leishmaniasis patients and predictor variables. Data analysis was carried out using R statistical software. The risk factors which were significant predictors for survival time of visceral Leishmaniasis patients included; household design (cracked walls and thatched roof) [β =.435, p=.0001], living near anthills [β =.320, p=.0012], using bed nets [β= -.151, p=.0080], contact with infected dogs [β =.200, p=.0006], forest surroundings [β=.151, p=.0340] and sleeping outside at night [β =.169, p=.0260]. In conclusion, there was an increased case of visceral Leishmaniasis among patients who are not using bed nets, those living in cracked mud walls, those living near the forest, residing near ant hills, sleeping outside, and those in contact with infected dogs. The study recommended adopting appropriate practices such as avoiding contact with infected dogs, using bed nets at night, clearing forests surrounding homesteads, avoiding sleeping in the open at night, and reducing house proximity to ant hills and termite mounds to reduce the transmission from Visceral Leishmaniasis.
