Cutaneous leishmaniasis in north-central Ethiopia: trend, clinical forms, geographic distribution, and determinants

BackgroundCutaneous leishmaniasis (CL), being among the neglected tropical diseases, catches little attention despite its considerable influence. This study aimed at estimating the prevalence and associated factors of CL in Boru Meda Hospital, Dessie town, north-central Ethiopia.MethodsMedical records of patients who attended the Dermatology Department of the Hospital in 2012-May 2018 were assessed. In addition, dermatological patients who were visiting the hospital during the data collection period (November 2017-May 2018) were interviewed to capture socio-demographic, environmental variables, and related factors. The source population was individuals who visited the hospital for skin problems in the stated years and CL positives were the targets. The association between CL and its determinants was tested by logistic regression.ResultsCL prevalence was 1.5% showing increasing trend with the year of examination. Localized, diffused, and mucosal CL was evident across the years. Dessie town had the highest prevalence, 291 (32.8%) patients out of 888 cases. The number of examined (29,701) and positives (543, 1.8%) for males was comparable with females, 28,459 and 345 (1.2%), respectively, increasing with age but without significant difference. Dessie town residence (adjusted odds ratio (AOR) 12.2, 95% confidence interval (CI) 2.2-18.6, p = 0.01), no bed net (AOR 9.9, 95% CI 2.7-16.7, p < 0.01), nearby irrigation (AOR 8.1, 95% CI 1.9-12.4, p < 0.01), and travel to CL endemic areas (AOR 13.9, 95% CI 4.4-14.3, p < 0.01) were significantly associated with CL.ConclusionCL is a growing health problem in Dessie and its surroundings. Known risk factors prevail. Comprehensive parasitological, entomological, and social studies are warranted to better manage the disease.
