C. H. Chuang is optimistic, because AIDS is not passed easily from person to person, but can only be passed through transference of blood or body fluids (especially sperm) through sexual intercourse, blood transfusions, common use of needles, and so on. Moreover, one does not certainly get AIDS at first contact; it often takes repeated contacts before the disease is transmitted.
愛滋病的感染媒介﹘﹘血液和體液（特別是精液），只有透過性交、輸血或血液製劑、器官移植、共用針具、傷口接觸，以及母子垂直感染等有限的幾種途徑才會散播；而且並不一定「一拍即合」，往往要反覆接觸才會被感染上。
