SARS stands for Severe Acute Respiratory Syndrome.

It is caused by the SARS-conavirus, it is a virus.

Mortality by age group as of 8 May 2003:

below 1% for people aged 24 or younger

6% for those 25 to 44

15% in those 45 to 64

more than 50% for those over 65

For comparison, the case fatality rate for influenza is usually around 0.6% (primarily among the elderly) but can rise as high as 33% in locally severe epidemics of new strains. The mortality rate of the primary viral pneumonia form is about 70%.

Those who are in the most danger from SARS are the elderly or those with other respiratory issues.
