Our work it is an interesting topic for all the world in our age. Diferent contries in special AsianS an Arabs Aare more relatinated with this global problem. Bioterrorism refers to the use of lethal biological agents to wage terror against a civilian population. It differs from biological warfare in that it also thrives on public fear, which can demoralize a population. Biological, chemical, and nuclear weapons can all be used to achieve similar destructive goals, but unlike chemical and nuclear technologies that are expensive to create, biological weapons are relatively inexpensive. They are easy to transport and resist detection by standard security systems. In general, chemical weapons act acutely, causing illness in minutes to hours at the scene of release. For example, the release of sarin gas by the religious sect Aum Shinrikyo in the Tokyo subway in 1995 killed 12 and hospitalized 5,000 people. In contrast, the damage from biological weapons may not become evident until weeks after an attack. If the pathogenic (disease-causing) agent is transmissible, a bioterrorist attack could eventually kill thousands over a much larger area than the initial area of attack. This is a problem that it is handle with a extreme caution. The ONU and anpther organizations wants to stop this menaze. The UEA is one of the principals contries that want to put an end to this. In this work you are going to fin d the hirtory and all the datails and information realted with this topic.
