The most serious threat would be posed by the biological agent to which there is no immediate defense or antidote. Antibiotics would be effective against bacterial agents such as Bacillus anthracis and Yersinia pestis, and antitoxin against diphtheria and botulism toxins could be administered to those affected. If the powder contained the smallpox virus, however, the population would be particularly susceptible, because there are no antibiotics available to protect the non-immune population, and vaccination would take time to take effect. Those infected in the initial attack could spread this highly infectious virus, which has severe morbidity and a mortality rate of about 30%.
