Epidemiological features of cutaneous leishmaniosis and related factors in Bushehr province, southwest of Iran.

Cutaneous leishmaniosis (CL) is one of the most important known infectious skin diseases, and Iran, as a country at high risk of leishmaniosis. This research was carried out to describe the epidemiological status of cutaneous leishmaniosis during 2011-2018 years in Bushehr province. Total, 929 cutaneous leishmaniosis patients were registered in the Bushehr province during this period. Data analysis was carried out using IBM SPSS Statistics, version 22. The data were analyzed using the descriptive statistics, Chi-square test, and Fisher's exact test. The highest frequency was related to the age group of 1-10 years (35.1%). The patients consist (60.4%) males and (39.6%) females. The highest and lowest rates of disease were found in 2011 (16.3%) and 2017 (6.6%), respectively, and in January (16.6%) and September (3.2%), respectively. In terms of the ulcer number, (51%) of the cases had one ulcer, and (23%) had (3-5) ulcers. Dry ulcers made up (68.2%) of ulcers, while the wet ulcers made up (31.8%). The hands had accounted for (37%) of ulcers, the face for (25%), and the feet for (21%). Age of cases was significantly associated with the number and site of ulcers (P<0.001). As well, there was a significant relationship between gender and the number of ulcers (P<0.035). This eight-year study confirmed that in Iran, Bushehr province is one of the endemic areas for the cutaneous leishmaniosis. The increase in the patients in 2018, despite its decrease in previous years, is an alert for coming years. Effective disease prevention, control, and treatment measures are essential. Furthermore, the children, who are a vulnerable population, need the special care and treatment.
