Abstract

Objective To analyze the disease distribution characteristics of scrub typhus in Nanfeng County, Jiangxi Province, China, so as to provide a scientific basis for developing rational and effective prevention and control measures to prevent and control scrub typhus.Methods Descriptive epidemiological methods were employed to analyze the data about scrub typhus reported cases in Nanfeng County from 2010 to 2022. The incidence, distribution (by time, space, and population), and trend of scrub typhus were analyzed by using seasonal decomposition analysis, joinpoint regression analysis, the Cochran-Armitage test for trend, Pearson's Chi-square test, and Fisher's exact test.Results From 2010 to 2022, a total of 1 548 cases of scrub typhus were reported in Nanfeng County, with an average annual incidence rate of 42.54/100 000. The reported cases were predominantly farmers. In the age group of >30-70 years, the incidence rate was significantly higher in women than in men (χ²=49.797, P<0.001); but there was no significant difference in the age group of >30-40 years (χ²=1.885, P=0.170), while women aged >40-70 years had a high incidence rate. The joinpoint regression analysis indicated an overall upward trend in the annual average incidence rate of scrub typhus (average annual percent change=18.25 %). The seasonal decomposition analysis revealed significant seasonality of scrub typhus, with double peaks in summer (June to August) and autumn and winter (September to December). The annual average incidence rates of townships could be divided into three stages:low-level epidemic stage between 2010 and 2013 (≤ 5.00/100 000), high-level epidemic stage between 2014 and 2018 (>10.00/100 000), and fluctuation stage between 2019 and 2022 (≤ 10.00/100 000).Conclusions The incidence of scrub typhus is relatively high in Nanfeng County. During epidemic seasons, health promotion and education should be strengthened for key populations to reduce the incidence of scrub typhus.
