World Hepatitis Day is observed on 28 July each year to enhance the awareness of viral hepatitis. The theme in 2020 is "Hepatitis-free future", focusing on the prevention of mother-to-child transmission (MTCT) of hepatitis B virus (HBV). The map shows the global prevalence of HBV infection among children aged five or below in 2015, which is one of the core indicators for viral hepatitis elimination.

As depicted by graduated colours, most of the countries outside Africa has met the global targets for 2020, achieving an HBsAg prevalence of less than 1% among children. However, only a few countries could reach the global 2030 targets at less than 0.1% HBsAg prevalence in children. As indicated by graduated symbols, five countries had more than 400,000 children under five years of age living with HBV infection, namely China, India, Pakistan, Nigeria and South Sudan. To prevent MTCT of HBV, ensuring high coverage of three-dose hepatitis B vaccination is vital.

世界肝炎日定於每年的7月28日，旨在提升公眾對病毒性肝炎的認識。2020年世界肝炎日的主題為「沒有肝炎的未來」，特別關注乙型肝炎母嬰傳播的預防措施。地圖顯示2015年全球五歲以下兒童的乙型肝炎流行情況，而這亦是評估消除病毒性肝炎進程的其中一個核心指標。

依圖中顏色所示，在非洲以外的大部分國家，兒童的乙型肝炎表面抗原陽性率已低於百分之一，達到2020年的全球目標。不過，只有少部分國家達到2030年的全球目標，即兒童的乙型肝炎表面抗原陽性率低於百分之零點一。依圖中圓點所示，共五個國家有超過四十萬名五歲以下兒童患有乙型肝炎，分別為中國、印度、巴基斯坦、尼日尼亞及南蘇丹。要預防乙型肝炎母嬰傳播，確保兒童完成接種共三劑的乙型肝炎疫苗至為關鍵。
