I just completed the Bio-Terrorism module for our team so the material is as fresh as possible for someone of my age!<br><br>Regarding your comments about viral agents, smallpox and ebola are rarely survivable. The Russians attempted to genetically combine the viruses so that someone exposed would contract both Ebola and Smallpox. Each has a 80-95% mortality rate. No one would survive the combined infection.<br><br>The most likely Bio threat is anthrax. The organism is readily available, easy to manufacture and distribute, and has a high lethality. It is not transmissible from person to person and therefore a "controllable" agent. Dispersed at the superbowl, it would likely kill most everyone infected, but not others that they come into contact with, such as health care workers and family members, etc.<br><br>The cult that dumped SARIN in the Tokyo subway tried UNSUCCESSFULLY to develop Anthrax as a weapon. It is easy for governments to do, less so for terrorists.<br><br>Viral agents and bacterial agents that are capable of spread from infected to healthy people are not controllable. Should Ebola or Smallpox be released in a terrorist incident, there is potential to spread the infection internationally. It is not reasonable to think that those immediately infected would die before infecting others. Ebola is spread through contact with infected secretions, Smallpox is spread as colds and influenza by aerosol droplets.<br><br>Those of us that are old enough to have Smallpox vaccination scars are NOT protected against Smallpox today.<br><br>The problem with infectious agents is that they can and will spread once delivered. This makes them a less than suitable weapon.<br><br>Remember that the THREAT to employ chemical and biological weapons is far more a concern than the actual release. We all remember images of the troops during desert storm wearing their MOPP gear and hunkering down in bunkers, unable to do much of anything more, when there was a THREAT of a chemical release.<br><br>Imagine the effect on a large city if someone would announce that they had released or would release an agent at a given time. Imagine the panic and effect on our society.<br><br>It appears to me that the government is more concerned about a chemical threat than any other, followed by possibly anthrax. A distant third is a "suitcase" nuclear device.<br><br>Jeffery S. Anderson, M.D.<br><br>
