PANDEMIC SEVERITY INDEX
In February 2007, the US government released guidelines to help cities and states prepare for a flu pandemic. The guidelines included a Pandemic Severity Index designed to help officials predict the severity of an outbreak (based on early cases) and enact appropirate "mitigation strategies." All future pandemics in the US will be assigned one of these five categories:
|Cat.||case fatality *||excess death rate **||potential no. deaths||US 20thC experience|
|2||0.1-0.5||30-150||90,000-450,000||1957 & 1968|
* The proportion of deaths among the critically ill.
** The rateof death per 10,000 people compared to the normal "nonpandemic" rate.
