Chen Shou-chien says that overseas the rate of infection is higher from the sharing of needles by intravenous drug-users. But in Taiwan, there are relatively few intravenous drug-users and needles are easy to come by. Therefore this group accounts for a much smaller percentage of the island's AIDS cases.
性病防治所所長陳守堅指出，國外靜脈毒癮共用針頭感染的比例高，台灣由於靜脈毒癮者人數少、針頭取得容易，因此感染的人數相當有限。
