Discussing the national crisis management in medical field, the problems could be allocated into two groups. The one is long-term, chronic, and latent dangers and the other one is short- term, acute, and actual crises. Actual crises comprise the interruption of medical services, the large-scale epidemic of infectious diseases, bio- terrorism, and demographically the delivery of large number of premature new-born infants. Due to its' unique characteristics that the threat has undeniably changed and evoved, the national crisis which might be induced by bio-terrorism is very complicated and intimately connected with a number of the other national crises. The problem of delivering the large number of premature new- born infants should be considered as one of the grave acual national crises. Latent dangers are to lie in the urgent rescue and emergent medical care system, the national medical insurance system, and demographically low birth rate and the increase of aging population.
