One of those who carried out the survey, Shen Chih-yang, an associate research fellow at Academia Sinica's Institute of Biomedicine, says that most hantavirus found in Taiwan and the offshore islands is of the Seoul variety, which causes mild symptoms and has a low fatality rate. The more severe Hantaan variety of the virus is found only at CKS International Airport, Nanliao Harbor and Kinmen.
參與調查的中研院生醫所副研究員沈志陽指出，台灣老鼠帶有漢他病毒的比例最高的是國際海港，其次依序是國內港、都市、山區。而台灣地區的漢他病毒主要是症狀輕微、致死率低的「漢城型」，只有在中正機場、南寮漁港和金門地區有症狀較嚴重的「漢灘型」漢他病毒存在。
