In 2022, 254 million people were living with and around 1 million died from chronic hepatitis B, as estimated by World Health Organization (WHO). The current antiviral therapy could effectively suppress HBV viral load leading to reduction of morbidity and mortality. WHO recommends adult HBV testing in places with HBV prevalence of at least 2%.

The bivariate choropleth map shows the geographic distribution of estimated HBV prevalence and proportion of diagnosis. Countries in light green to green, such as those in North and South America, as well as Australia, show low HBV prevalence (<2%) with different proportions of diagnosis. The dark green areas, such as China and Mongolia, are places with HBV prevalence above 5% and diagnosis rate over 30%. Countries in brown (except dark brown), such as those in South-East Asia and Africa, have higher HBV prevalence (≥2%) but with the diagnosis of only 30% or below, suggesting scale-up of HBV testing is needed.

28 July is World Hepatitis Day, aiming at raising public awareness of viral hepatitis. To know more, you could browse the suggested webpages in "Other resources" below.

世界衛生組織（ WHO ）估計2022年全球有2.54億人患有慢性乙型肝炎(HBV)及約一百萬人因此死亡。現時的抗病毒治療能有效地抑制 HBV病毒載量，從而降低患病和死亡數字。WHO建議在HBV發病率有2%或以上的地方，成年人測試HBV。

二元分區著色圖顯示HBV發病率及確診百分比的地理分佈。淺綠色至綠色地方，如北美洲、南美洲國家和澳洲，顯示HBV發病率較低（<2%），而診斷率各異。深綠色區域，例如中國和蒙古，為HBV發病率多於5%但診斷率>30%的地方。棕色區域（深棕色除外），例如東南亞和非洲國家，顯示HBV發病率較高（≥2%），但診斷率僅30%或以下，提示需要擴大HBV檢測規模。

每年的7月28日是世界肝炎日，旨在提升公眾對病毒性肝炎的認知。想了解更多，可瀏覽 ”其他資訊” 所提及的網頁。
