Identification, verification and response to acute
chemical incidents
On a daily basis, information from a range of informal and formal
sources was reviewed to identify acute chemical incidents
and outbreaks of disease of unknown etiology that might be of
chemical origin. The principal informal sources were the Global
Public Health Intelligence Network (GPHIN), ProMED-Mail,
and Hazard Intelligence (HInt) (Box 1 contains further information
on these sources), as well as other news media.
