The World Hepatitis Day is observed every year on 28th July. “Time To Test. Time To Treat. Time To Cure” is the slogan of World Hepatitis Day for 2018. In 2015, a total of 257 million and 71 million people were estimated to be living with Hepatitis B (HBV) and Hepatitis C (HCV) virus, respectively. However, only 8% of the HBV-infected individuals and 20% of the HCV-infected individuals were diagnosed.

The upper map shows the prevalence of HBV, and the lower map shows the prevalence of HCV in 2015. The highest HBV prevalence was noted in African and Western Pacific regions (around 6%), while the highest HCV prevalence in Eastern Mediterranean region (2.3%). However, less than 2% of HBV-infected individuals were diagnosed in African and Western Pacific regions, and less than 20% of HCV-infected individuals were diagnosed in Eastern Mediterranean region. In contrast, in European and American regions, the HBV and HCV prevalence was lower, but the diagnosis rate of HBV and HCV was higher. In other words, very few people living with these infections are aware of their conditions outside developed countries.

WHO has set a target of achieving 90% diagnosis rate of both HBV and HCV by the end of 2030. The figures shown in 2015 fell short of the target. More efforts and resources are needed to achieve the goal.

Data for the map were obtained from World Health Organization.


上圖顯示2015年全球各地區乙型肝炎的感染率,下圖則顯示丙型肝炎的感染率。非洲和西太平洋地區的乙型肝炎感染率最高 (大約6%),而東地中海是丙型肝炎感染率最高的地區 (2.3%)。但是,非洲和西太平洋地區的乙型肝炎的確診比例小於2%和東地中海地區的丙型肝炎的確診比例小於20%。相反,在歐洲和美洲地區,乙型肝炎和丙型肝炎感染率較低,但確診比例較高。換言之,只有少數在發達國家以外的感染者知悉自己的情況。

世界衛生組織訂立了一個目標,期望在2030年乙型肝炎和丙型肝炎的確診比例可達到90% 。可是,按照2015年數據所反影的情況,離目標依然有大段的距離。要達到目標便需要投放更多的資源及努力。
