During 2015 and 2016, 251 cases of acute hepatitis C were reported fromsix counties in TaipeiRegion, 169 were confirmed, 125(74%)were male and 61(36%)were HIV-infected. The median age of confirmed caseswas 44 years-old (range:20–90years-old). Nearly 73% of thesecases were residing in Taipei City and New Taipei City. However,the age-adjustedstandardized incidence per 100,000 populationsin 2015 and 2016 revealed that Yilan County (3.18) and Keelung City (2.66) were the highest. Forty-five percentof infected cases co-infected with HIVwere residing in the large metropolitan areas such as Taipei City and New Taipei City. Among them, one-third had unsafe sexual behaviorin men having sex withmen(MSM). ComparedwithKeelung and Yilan, the casesin Metropolitan areahada relatively high proportion of unsafe sexual behavior within 3 months, but a relatively low proportion of usingintravenous drugs, needle/diluentsharing, or contacting blood through either wound or mucosa by accident.The analysis shows that unsafe MSM sexual behavioramong HIV-infected people in large metropolitan areas poses highriskof hepatitis C infections, presumablydue to anal mucous membrane damage caused by sexual behavior, which increases the risk of infection. Therefore, the public health departmentshould arrangethe appropriate prevention and control strategies as early as possible according to the demographic characteristics of different regions and the risk factors of the cases, in order to enhance the effectiveness of prevention and control. |
