Objective To analyze the time,regional,and population distribution of scrub typhus cases reported in Qingdao,Shandong Province,China,so as to provide a scientific basis for the prevention and control of scrub typhus in the future.Methods The information on scrub typhus cases in Qingdao from 2006 to 2022 was collected and statistically analyzed by Excel 2010 and SPSS 22.0 softwares.The incidence rate as well as characteristics and variation trends of time,regional,and population distribution of scrub typhus were analyzed by the joinpoint regression and Chi-square test.Results From 2006 to 2022,1112 cases of scrub typhus were reported in Qingdao,with an average annual incidence of 0.74/100000,and no death cases were reported.Scrub typhus cases were reported from March to December,of which October and November were the peak months of reported incidence,with cases accounting for 96.13％ of the total cases.Scrub typhus cases were reported in all age groups,with a significant difference in the incidence rate (x2=1266.119,P<0.001).Males in the 60-<65 years old group (93 cases) and females in the 55-<60 years old group (106 cases) had the highest cases reported.The top five cities (districts) in average annual incidence were Laixi City (2.42/100000),Jimo District (1.49/100000),Huangdao District (1.11/100000),Jiaozhou City (0.58/100000),and Pingdu City (0.40/100000),with a significant difference in the reported incidence (x2=1050.577,P<0.001).Farmer (85.16％) was ranked the first in occupation for scrub typhus infection.Conclusions The incidence of scrub typhus in Qingdao from 2006 to 2022 presents significant regional and seasonal variations.Farmers are at high risk of scrub typhus.It is suggested that extensive health education about scrub typhus prevention and control should be carried out for key populations in key areas,and multiple effective measures should be taken to strengthen the surveillance of vectors and host animals and control the infection level of scrub typhus.
