The WHO claims that the age group is an important factor in the survival rate of Severe Acute Respiratory Syndrome, revising previously-held opinions that the death rate was 4%. Based on the latest data from Canada, Vietnam, China (including Hong Kong) and Singapore, it has stated that the real death date is overall 14-15% and up to 50% in the senior citizen age bracket.

In persons 24 years of age or younger, the death rate is 1%, in the 25-44 age group, 6% while in the age group between 45 and 64, it is 15% and over 50% among people over 65.
