In Sudan, human leishmaniasis is endemic, and the prevalence of the disease varies throughout the country. Although the disease in Sudan is serious, there is no overall estimation of the prevalence of human leishmaniasis in the western parts of the country, especially in the West Kordofan state.
The lack of published studies about human leishmaniasis in the western parts of Sudan especially in the West Kordofan state may cause a problem for the policymakers and local governments to develop and adopt a suitable prevention program to deal with the disease at the state level and the country level.
The objective of this study was to find the frequency and distribution of human leishmaniasis based on sex and age in West Kordofan, Sudan for 5 years.
A 5-year retrospective study from 2016 through 2020 was carried out using local hospital records of leishmaniasis patients. The positive results were recorded after performing at least one of the following leishmaniasis standard tests: direct agglutination test, enzyme-linked immunosorbent assay and leishmania skin test.
A total of 162443 patient records from 2016 to 2020 were retrieved. Of these, 4.39% were found to be positive for leishmaniasis. The disease has been more common in males (65.3%) than in females (34.7%). The highest reported prevalence (6.58%) was in patients 15-44 years, and the lowest prevalence (1.95%) was among patients ≥ 65 years.
The results of the current study indicate that leishmaniasis is endemic in the study area even though the numbers of patients in the 5 consecutive years were varying. In addition, the disease was common in males and adults.
Further studies need to be carried out to clarify the economic impact of the disease on the public health sector in the state and the role of domestic animals in the epidemiology of the disease in Sudan.
