Hepatitis B poses a major public health threat in China, where an estimated 7% of the population aged 1 - 59 is chronically infected with hepatitis B virus (HBV). Between 2005 - 2009, the reported number of hepatitis B cases per 100000 population has increased by 18% in the country. The map shows the distribution of hepatitis B cases in 2009 and the changes over the preceding five years.

As depicted by graduated colours, north-western China reported the highest number of hepatitis B cases, in contrast with lower numbers in south-western and eastern China. As indicated by coloured arrows, hepatitis B cases clustered in western and southern China while a decrease can be seen in the east and Sichuan. To control HBV infections in China, strengthening the current vaccination programme is paramount, especially in rural areas and western regions. The first official WHO World Hepatitis Day is marked on 28th July 2011 to enhance public awareness and improve understanding of viral hepatitis, of which HBV is a major focus.

Data for the map was obtained from the Ministry of Health of the People's Republic of China.

乙型肝炎為中國帶來嚴重的公共衛生問題,全國約百分之七人口是慢性乙型肝炎病毒帶原者。2005年至2009年間,中國每十萬人計的年度乙型肝炎病例數目增幅達百分之十八。地圖顯示全國各省的乙型肝炎病例分佈及該五年間的變化。

依地圖顏色所示,中國西北部的人口平均乙型肝炎數目最高。相對之下,西南部及東部地區的個案則較其他省份為低。顏色箭號標示中國乙型肝炎多集中於西部及南部,相反華東及四川等地的乙型肝炎病例則按年減少。要有效控制中國的乙型肝炎感染,必須改善疫苗接種規劃,而針對農村及西部地區至為重要。世界衛生組織已將7月28日訂為世界肝炎日,旨在提高公眾對病毒性肝炎的認知與關注,而乙型肝炎顯然是一個重點。
