To investigate the current incidence of the infection after the contraceptive operation and its epidemiological trend, and to call on the medical and health industry to pay enough attention to the problem of the infection after the contraceptive operation. Methods: The incidence of the infection after the contraceptive operation was calculated using the data from China's Health Statistics Yearbook monitored between 2007 and 2020, which including the insertion and removal of intrauterine devices (IUD), the tubal sterilization, and the abortion. The estimated values of the annual percent change (APC) and the average annual percentage change (AAPC) were counted by Joinpoin regression model, and the trend analyses of the infection rates after the contraceptive operations were analyzed. Results: According to the data from China's Health Statistics Yearbook monitored between 2018 and 2020, the current infection rates of the patients after abortion, tubal ligation and IUD inserted (removal) in China were approximately 7.3/100,000, 5.6/100,000 and 5.6/100,000, respectively, and the overall infection rate of the patients after abortion, tubal ligation and IUD inserted (removal) was 6.6/100,000. From 2007 to 2020, the overall infection rate after the contraceptive operation, the infection rate after IUD inserted (removal) and the infection rate after abortion of the patients showed a decreasing trend, and the AAPC of which were -10.9%, -9.9% and -7.2%, respectively (all P<0.05). From 2007 to 2020, the infection rate of the patients after tubal ligation showed a decreasing trend (AAPC=-14.4, P<0.05), but the decreasing trend of the infection rate of the patients after tubal ligation had statistical significance from 2007 to 2012 (APC=-9.5, P<0.05). Conclusion: The prevention and control of the infections after the contraceptive operation in China has made the remarkable achievements, and the infection rate after the contraceptive operation is low, but the follow-up and the monitoring work after the contraceptive operation is still difficult, and which should be further paid attention to and be researched.
