Epidemiological characteristics of confirmed mpox cases in Sichuan Province in 2023
Objective To analyze the epidemiological and clinical characteristics of confirmed mpox cases in Sichuan Province in 2023 and to provide a scientific basis for the prevention and control of the mpox epidemic,and provide reference for the prevention and control of other emerging infectious diseases.Methods The data were collected from the information of confirmed mpox cases residing in Sichuan Province reported in the National Infectious Disease Reporting Information Management System until 24:00 on December 31,2023,as well as the epidemiological investigation report of mpox cases.Excel 2020 software was used to input,sort out and plot the data,SPSS 23 statistical software was used to analyze the data,and descriptive epidemiological methods were used to analyze the basic characteristics of the cases.Results The first mpox case was reported in Sichuan Province on June 30,2023,and the peak period of reported cases was from July to August.As of December 31,2023,a total of 141 mpox cases had been reported.The cases were predominantly male(99.3%),aged 30-<40 years(49.6%),and MSM(men who have sex with men,accounting for 93.0%of male cases).35.4%of cases reported HIV infection.The interval from onset of symptoms to diagnosis ranged from 2 to 90 days,with M(P25,P75)being 4(6,8)days.The incubation period for cases ranged from 1 to 21 days,with M(P25,P75)being 7(4,10)days.The majority of cases were discovered through proactive medical consultation(96.4%).The initial symptoms were rash(70.9%)and fever(31.2%).The main symptoms were rash(95.7%),fever(55.3%),and lymph node enlargement(35.5%).Conclusion Mpox outbreaks mainly occur in MSM population.It is necessary to make full use of the comprehensive intervention service system for AIDS prevention and treatment to publicize and educate key groups,timely monitor the variation of monkeypox virus,especially strengthen the surveillance of inbound cases,implement early detection and control of cases,and reduce the risk of epidemic transmission.
