Objective:To analyze the distribution characteristics and trends of hepatitis B in Harbin and provide evidence for the development of hepatitis B prevention and control strategies.Methods:Descriptive epidemiological methods were used to analyze the three-dimensional distribution characteristics and epidemiological trends of hepatitis B data in Harbin from 2010 to 2023.Results:A total of 38,604 cases of hepatitis B were reported in Harbin from 2010 to 2023,with an average annual incidence rate of 26.38 per 100,000.The majority of hepatitis B cases were chronic.There was no obvious seasonal distribution pattern of hepatitis B.The average incidence rate was lowest in the<10-year-old group(1.72 per 100,000)and highest in the 40-year-old group(34.71 per 100,000).Cases were mainly concentrated in the 30-69-year-old population,accounting for 75.35%.The male-to-female ratio was 1.35:1.The majority of cases were farmers,accounting for 57.31%.Conclusion:Except for a significant decrease from 2020 to 2022,the overall incidence of hepatitis B showed a trend of decreasing first and then increasing from 2010 to 2023.The prevention and control measures for the 0-19-year-old population were effective.It is necessary to strengthen the prevention and control of hepatitis B among adults over 20 years old,especially to develop differentiated hepatitis B prevention and control strategies targeting key areas and high-risk populations.
