Yeh recounts that when he saw the plans to separate SARS patients from non-SARS patients at the Chung-ho and Chang Gung hospitals, he realized that there wasn't much to worry about: "I only went there to endorse their work. People trusted me and thought that I wouldn't cover up any mishandling."
他說，看完高醫和高雄長庚的院內分區計畫，就知道沒問題，「我只是去背書，大家相信我不會亂說、不會掩蓋事實。」
