The most common question which come to the mind after the Sept 11 2001 attack on World Trade Centre is "What Next"? Bio-terrosism is one of the most feared and fatal options available to the terrosist of this world. Medindia. net will carry an extensive write up on this aspect over the next few weks.

Definition : Bioterrorism is the unveiled or veiled dispensing of disease pathogens by individuals, groups, or governments for the expressed purpose of causing harm for either ideological, political, or financial gain. Biological weapons have been called "the poor man's atom bomb."

The threat of biological or chemical weapons being used can have staggering consideration. Unfortunately, experts believe that there is a very real possibility that this will happen. To mount an effective response to biological or chemical terrorism, people should be informed and educated about how such weapons can be used and what illnesses will occur as a result. Until recently, biological terrorism had been little discussed or written about.

A comprehensive review of the problems posed by biological terrorism and warfare has been published. Four observations deserve special note. 1.Biological terrorism is more likely than ever before and far more threatening than either explosives or chemicals. 2. Official actions directed at the threat to the civilian population (less than 2 years in the making) have been only marginally funded and minimally supported. 3. Preventing or countering bioterrorism will be extremely difficult. Recipes for making biological weapons are now available on the Internet, and even groups with modest finances and basic training in biology and engineering could develop, should they wish, an effective weapon at little cost. 4. Detection or interdiction of those intending to use biological weapons is next to impossible.

Thus, the first evidence of such weapons will almost certainly be cases in hospital emergency rooms. Specialists in infectious diseases thus constitute the front line of defense. The rapidity with which they and emergency room personnel reach a proper diagnosis and the speed with which they apply preventive and therapeutic measures could spell the difference between thousands and perhaps tens of thousands of casualties.

Indeed, the survival of physicians and health-care staff caring for the patients may be at stake. However, today few have ever seen so much as a single case of smallpox, plague, or anthrax, or, for that matter, would recall the characteristics of such cases. Few, if any, diagnostic laboratories are prepared to confirm promptly such diagnoses.

Dissident nations, groups, and individuals have been turning to biological agents as a means of conducting warfare or terrorism. Many microorganisms and toxins are relatively easily acquired, and some can be mass-produced as aerosolized biological weapons. Inhalation of and other contact with these agents by large numbers of people could lead to mass casualties. Yet many experts say that the probability of a large-scale attack is greater today than ever before. It is probably not a case of if, but when. Public health and emergency officials believe it is increasingly important for our health care system to be prepared for a bioterrorist strike. Likewise, it is paramount that hospital emergency departments recognize the signs and symptoms of exposure to biological agents and initiate immediate and appropriate treatment.
