Fighting an epidemic is like waging war: it requires horizontal coordination. Private and public hospitals must plan in advance which roles each will play the day biochemical war breaks out. As Sun Zi put it in The Art of War, "Do not depend on the enemy not coming; depend rather on being ready for him."
防疫如同作戰，確實需要橫向協調，假設今天是發生生化戰，私人醫院、公立醫院各自要扮演什麼角色，都要預先假想，也就是要有「不恃敵之不來，恃吾有以待之」的準備。
