Abstract:
Objective:To study the epidemic characteristics of scrub typhus in Yantai City from 2006 to 2022, and provide a scientific basis for prevention and control of scrub typhus in Yantai City.Methods:In the subsystem "Infectious Disease Monitoring System" of the "China Disease Prevention and Control Information System", data on the outbreak of scrub typhus in Yantai City from January 1, 2006 to December 31, 2022 were collected and processed using software such as SPSS 23.0 for descriptive statistics.Results:A total of 599 scrub typhus cases were reported in Yantai City from 2006 to 2022, with an average annual reported incidence of 0.51/100 000. The reported incidence showed an upward trend year by year from 2006 to 2014 (χ 2trend = 144.72, P < 0.001), and reached a peak in 2014 (1.04/100 000). There was another small peak in 2019 (0.91/100 000). The incidence of scrub typhus showed a clear seasonal unimodal distribution, with October being the peak, accounting for 72.62% (435/599). In addition to Changdao County, other 12 cities (districts) reported scrub typhus cases. The top 3 cities with average annual reported incidence were Zhaoyuan City (1.58/100 000), Laizhou City (1.47/100 000) and Laiyang City (0.75/100 000). In all reported cases, the male to female ratio was 1.00∶1.07 (289∶310). The cases were mainly concentrated in the age range of 50 to 79, accounting for 74.46% (446/599). There was a statistically significant difference in the number of patients in different age groups in different years ( H = 38.71, P = 0.001). Farmers accounted for 88.65% (531/599) of the affected population. Conclusions:The incidence of scrub typhus in Yantai City shows an increasing trend and is widely distributed. It is recommended to strengthen the diagnosis, monitoring and infection management of scrub typhus.
