Epidemiological characteristics of hepatitis B in Guangzhou, 2005–2018

  Objective  To analyze the epidemiological characteristics and trend of hepatitis B in Guangzhou during 2005–2018, and provide evidence for the effective prevention and control of hepatitis B.

  Methods  The hepatitis B surveillance data in Guangzhou during the period were analyzed using descriptive epidemiological methods.

  Results  From 2005 to 2018, a total of 285 648 hepatitis B cases were reported, and the annual incidence rate was 166.81/100 000. The annual average reported incidence rate of acute hepatitis B and chronic hepatitis B were 6.68/100 000 and 145.43/100 000, respectively. The incidence rate of hepatitis B in some non-central areas (Zengcheng, Conghua and Nansha) increased during 2012–2018 compared with that during 2005–2011. Acute hepatitis B mainly occurred in age group 15–44 years, while the chronic hepatitis B mainly occurred in age group 30–44 years. The reported incidence of chronic hepatitis B in age group >45 years was higher during 2012–2018 than during 2005–2011, but the reported incidence rate in other age groups decreased with varying degrees. The incidence rate was higher in men than in women.

  Conclusion  It is necessary to pay attention to the epidemiological characteristics and trend of hepatitis B, strengthen the prevention and control of hepatitis B in adults, especially the high-risk groups, and accelerate the elimination process of viral hepatitis.
