Many misinformed people have come on these threads with closed minds and nothing to contribute except insults. Sometimes they go away after learning a bit, but rarely do they own up to their mistakes.
As you know, the typical uninformed SARS "debunker" is fond of saying SARS is "just the flu". It's a small point relative to the overall thread, but it looks like you slipped a decimal point.
You said: Ordinary flu has around 1% mortality rate for all patients. The actual number is 0.1%. That makes SARS 150 times more deadly, with much more damage for the survivors.
Source: The CDC estimates 35,000 people die from flu every year, and between 30 million and 50 million people catch it.
Variants of influenza type "A" are the killer. The CDC statistics I read did not break it out separately, but it would certainly be higher than the mortality rate for "all flu" combined.
