- Abstract: Objective To analyze the epidemiological characteristics of hepatitis A in Guangxi from 2010 to 2020, and to provide a scientific basis for formulating effective prevention and control strategies. Methods Descriptive epidemiological method was used to analyze the incidence data of hepatitis A in Guangxi from 2010 to 2020. Results From 2010 to 2020, a total of 8,742 cases of hepatitis A were reported in Guangxi, with an average annual incidence rate of 1.66 /100,000. There were 5 298 male cases (60.60%), and 3,444 female cases (39.40%). The incidence rate decreased from 2.73/100 000 in 2010 to 1.38/100 000 in 2020. The onset seasonality was strong in 2010, but there was no obvious seasonality in other years. A total of 5 891 cases (67.39%) were aged from 25 to 64 years. Farmers accounted for 59.79% of the cases. A total of 7 hepatitis A outbreaks were reported during 2010-2020, including 273 cases，accounting for 3.12% of the total cases．The incidence rates of hepatitis A in Hezhou (3.97/100 000), Wuzhou (2.98/100 000), Hechi (2.44/100 000), Guigang (2.00/100 000) and Beihai (1.79/100 000) were relatively higher than other places. Conclusion The number of reported hepatitis A cases in Guangxi has been declining year by year, and the prevention and control measures of hepatitis A vaccine prevention are effective. The surveillance of hepatitis A should be strengthened, and prevention and control strategies should be formulated for high-risk areas and key populations.
