Poisoning with many chemical agents, especially nerve agents, can be treated
when diagnosed early but early symptoms of disease induced by a
biological agent may be non-specific and difficult to recognise. In
the Clinical Review section, Evison and colleagues (p 332)
and Beeching and colleagues (p 336)
describe chemical and biological agents
how
they can be used as weapons, their effects, and the treatment
required. They call for health professionals to be better informed
and for rehearsal of responses to the possible use of biological and
chemical agents.
