To analyze the epidemiological characteristics of Hepatitis A virus (HAV) in Xinjiang from 2005 to 2023,providing a scientific basis for its prevention and control.
Descriptive epidemiological methods were employed to analyze the epidemiological characteristics of HAV reported in Xinjiang from 2005 to 2023 using data from the Chinese Disease Prevention and Control Information System.
A total of 55 586 cases of HAV were reported in Xinjiang from 2005 to 2023, with an average annual incidence rate of 14.54 per 100 000. The incidence rate decreased from 31.19 per 100 000 in 2005 to 0.75 per 100 000 in 2023. The regions with the highest incidence rates were Kizilsu (31.45 per 100 000) and Hotan (24.55 per 100 000). The majority of cases were among scattered children (39.70%). The age group with the highest incidence was 0 to 15 years (36.08%). The gender ratio decreased to 1.00 by 2023.
Between 2005 and 2023, the prevention and control measures for HAV in Xinjiang were significantly effective. Continued efforts in vaccination and enhanced comprehensive prevention measures for children are necessary.
