The fact is that doctors who examine symptoms without looking into the cause of diseases take a big risk. The SARS epidemic has shown that simply prescribing an antipyretic to a patient running a fever is pointless. Instead, physicians need to conduct transdisciplinary pathogenic analyses comprising tests on bacterial cultures, blood serum, blood samples, and the like.
事實上，醫生診斷若只看症狀，不探討病因，是很危險的，從這次 SARS 就可以知道，對發燒病人如果只開解熱藥，完全沒有效，應該要進行的是從細菌培養、從血清與血液分析病因，類似這樣的病理探討則需要跨科整合。
