Public health and the interface with the health care system are therefore key elements in any effective response to bioterrorism.   Whether the biggest threat is natural or engineered much remains to be done.Efforts to strengthen surveillance and response worldwide and to improve munication must be accelerated and sustained.Further,we have only scratched the surface in terms of understanding the ecology of infectious diseases and developing strategies for regulating microbial traffic.We need tools for better predictive epidemiologic modeling when a new infection first appears and for better analysis of the factors that transfer pathogens across species.One encouraging development is the program in the ecology of infections diseases that was started a few years ago be the National Science Foundation in cooperation with NIH.    SARS is a good yardstick of our progress during the past 13 years.The syndrome was unusual because novel infections that spread from person to person are relatively rare.Once cases were finally reported, the public health response was vigorous.WHO warned health care providers, researchers rapidly identified a candidate virus, and prototype diagnostic tests quickly became available.The vast reach of the Internet was instrumental in sharing formation and coordinating activities worldwide.Despite these advances, SARS had already spread to many countries.In fact had the disease been as transmissible as influenza, it would have invaded virtually every country in the world by the time the public health response had begun.So what SARS tells us is that although we have e long way since 1990, we still have a long way to go.1.[不定向选择题]From the text we learn that__________.A.bioterrorism is an engineered threat to human beings B.bioterrorism can be arrested by improving munication C.natural infections and bioterrorism are the same in essence D.the anthrax attacks are more threatening than the outbreak of SARS 2.[不定向选择题]The example of SARS is used to illustrate that__________.A.much remains to be done in improving the public health system B.the sooner the cases of infectious diseases are reported the better C.WHO is an indispensable organization D.Internet plays a very important role in fighting against infectious.
