Abstract：Objective To analyze the epidemiological characteristics and trends of viral hepatitis B in Yuxi City from 2005 to 2020, so as to provide scientific evidence for the prevention and control of viral hepatitis B in the future. Methods A descriptive epidemiological method was used to analyze the epidemiological data of hepatitis B and hepatitis B carriers reported by the disease surveillance information reporting management system in Yuxi City from 2005 to 2020. Results From 2005 to 2020, a total of 11 721 cases of hepatitis B were reported, with an average annual incidence rate of 32.44/105, showing a downward trend in 16 years (χ2trend=1 244.406, P=0.001). A total of 17 179 hepatitis B carriers were reported, with an average annual reporting rate of 46.59/105, but the overall trend was increasing (χ2trend=824.577, P=0.002). There was a statistically significant difference in the annual incidence of hepatitis B cases reported by each county (χ2=26.214, P=0.011), and the top three counties were 54.57/105 in Huaning County, 41.37/105 in Yimen County, and 40.36/105 in Tonghai County. The average annual reporting rate of hepatitis B carriers in each county was statistically significantly different (χ2=81.360, P=0.015), and the top three counties were Huaning County (201.60/105), Esan County (75.03/105) and Xinping County (58.34/105). More hepatitis B cases were reported in males than those in females (1.53∶1), and the occupation was mainly farmers/herders (64.18%), and the age range from 20 to 39 years old (40.22%) accounted for the highest proportion. The male-to-female ratio of hepatitis B carriers was 1:1, the occupation was mainly farmers/herders (80.78%), and the age group was mainly the 20 —39-year age group (41.31%). Conclusion The situation of hepatitis B virus infection in Yuxi City is grim, and it is necessary to strengthen health education for people aged 20-39 years, especially the regular review and prevention of hepatitis B carriers in this age group, and improve vaccine coverage.
