"Back in 2002, Severe Acute Respiratory Syndrome or SARS killed about 10 per cent of the 8,000 people it infected in southern China and Hong Kong"
I asked the following question about H5N1, it seems to be just as relevent to SARS:
When H5N1 was doing the rounds in the UK, I, and my wife, and a lot of other people I knew, had long running and/or recurrent chest infections over a couple of months or so. None of us was ill enough to bother to go to the doctor, and there were enough people about with the same symptoms that we were still working, so we didn't need a medical report to miss work. So, we never got on any statistics for having something. My feeling (and my wife's, who is a biologist) is that its quite likely that a lot of people got H5N1 but were never diagnosed nor counted. This makes the claimed "H5N1 killed n% of people it infected" (whatever n% was) totally specious.
And I'd bet that the same is true of SARS. Unless there is random testing then nobody knows what the death rate is, and all these death rates are scare mongering by governments and the drugs industry,
