The map shows the distribution of reported acute cases of hepatitis B and C in Taiwan in 2007. For acute hepatitis B, Taipei County had the highest number of cases, 45, followed by Taipei City, 31 and Taoyuen County, 30 cases. For acute hepatitis C, the highest number reported was in Taipei County, 25, followed by Taichung City, 22, and Taipei City, 21 cases.

The prevalence of hepatitis B and C in the general population varies considerably. In Taiwan the hepatitis B carrier rate exceeds 10%, while that of hepatitis C is around 2-5%. With the introduction of universal hepatitis B vaccination, acute hepatitis B is becoming uncommon. On the other hand, hepatitis C has resulted from contaminated transfusion in the past. The current reported numbers may refer to those of injection drug users who are diagnosed with the infection because of needle-sharing. The two sets of reporting figures look similar but bear different meanings.

圖示二零零七年台灣急性乙型及丙型肝炎的呈報個案分佈。乙型肝炎方面,台北縣的呈報數字最高,達四十五宗,其次是台北市,三十一宗及桃園縣,三十宗。至於丙型肝炎,台北縣錄得最高呈報個案數字,達二十五宗,台中市,二十二宗及台北市,二十一宗。

乙型及丙型在人口流行程度有相當明顯的分別。在台灣,乙型肝炎帶原率多於10%,而丙型肝炎帶原率大約是2-5%。自從廣泛引入乙型肝炎疫苗接種後,急性乙型肝炎也不太常見。丙型肝炎以往曾因輸入不潔血液所致,近期的呈報個案數字則可能是指靜脈吸毒者,由於共用針筒而感染病毒。兩者的報告數據看似相同但含有不同的意義。
