Even with the technologic sophistication available in the United States tod
ay, effectiveness in dealing with a bioterrorist event is limited. Current
surveillance systems may be inadequate to detect attacks. Because the onset
of illness after exposure to an agent is delayed, even the time and locati
on of the attack may be vague. In addition, most of the medical community i
s unfamiliar with many of the high-threat diseases, so identification of th
e problem may be further delayed. Many of us who are involved in studying t
he many aspects of bioterrorism believe that it is not a question of if suc
h an event will occur but rather when, as well as which agent will be used
and how extensive the damage will be. Given the enormity of what is possibl
e, we must prepare for a potential nightmare.
