Abstract

Data of visceral leishmaniasis in Yangquan City from 2006 to 2021 was collected based on the current address and final audit date from the China Infectious Disease Information Reporting Management System. WPS office 2019 was used to establish the database for descriptive epidemiological analysis of visceral leishmaniasis. SPSS 20.0 was used for statistical analysis to compare the difference of rates between different groups. The analysis results showed that a total of 258 cases of visceral leishmaniasis were reported in Yangquan City from 2006 to 2021, with an average annual incidence rate of 1.18/100 000. The annual incidence increased over the years, from 0.08/100 000 in 2006 to 7.36/100 000 in 2021, and the difference was statistically significant among different years (χ2 = 441.984, P < 0.05). Visceral leishmaniasis cases were reported in five counties (districts) of Yangquan City, and the average annual incidence ranged from 0.50/100 000 to 4.05/100 000, with statistically significant differences among counties (districts) (χ2 = 70.770, P < 0.05). The age of visceral leishmaniasis cases ranged from 7 months to 85.81 years old, with a median age of 48.57 years old. The lowest incidence was in the 10-19 years old group (0.15/100 000), and the highest incidence was in the 0-9 years old group (2.96/100 000), with statistically significant differences among all age groups (χ2 = 20.564, P < 0.05). There were more males cases (180 cases) than females cases (78 cases), and the ratio of males to females was 2.31:1. Farmers and children had accounted for 64.73%（167/258）of all reported cases. There was no significant seasonal difference in the cases.
