Chang Shan-chwen, director of the Division of Infectious Diseases at National Taiwan University Hospital, thinks that the presence of HLA-B46 is not a necessary condition for a SARS infection to occur. People without this antigen can still get SARS, though their infection rate is lower.
台大感染科主任張上淳認為，HLA-B46 組織抗原並非感染 SARS 的必要條件，沒有此一抗原的人同樣可能感染，只能說感染率稍低。
