For the whole global village to be improved into an enormous "aseptic chamber" is surely impossible, but what we can predict is that if humans do not change their attitudes towards the environment and nature, and if they continue to pay scant regard to safe practice in medical treatment and the use of drugs, new viruses and infectious diseases will never stop appearing.
要將地球村改善成一個超大的「無菌室」恐怕很難，但可以預見的，只要人類不改變對待環境、自然的態度；只要人類繼續輕忽用藥、醫療安全，新的病毒、傳染病將繼續出現，源源不絕。
