With progress in medicine, the root cause of each type of communicable disease was discovered one after another. Mankind was also able to develop antibodies to all types of bacteria, so that we have long been able to prevent hepatitis B, tuberculosis, childhood polio, measles, and tetanus. Or, even after they are transmitted, antibiotics can be used to repress the disease and alleviate the threat of death.
隨著醫學發達，各種急性傳染病病原體一一被發現，人類也能針對各種病菌製造抗體，例如 B 型肝炎、肺結核、小兒麻痺、麻疹、破傷風… …，都能及早預防；或感染後，以抗生素有效地壓制病毒，解除致命的威脅。
