There is more detail at the Taiwan site

cdc.gov.tw

but I am still confused. The number of cases was reduced because 317 of the probable cases were negative for SARS CoV by PCR and antibody test. The number of cases with no clinical data is listed as 1, but I was under the impression that many cases (not just 1) did not have lab tests results because they had SARS symptoms but were cremated prior to collection of samples (which is why WHO listed 180 deaths instead of the 73 listed at the above site).

The site shows a case fatality rate of 21.1% for the SARS CoV positive cases. However, this number is almost cut in half by excluding 36 patients who were SARS CoV positive but are only "SARS related" because death was not "directly due to SARS", of which there were 37 (which is also the number in the updated WHO table).

It is also interesting that of the 73 who died and were SARS CoV positive, only 22 had a pre-existing conditions which means that 14 had no pre-existing condition, died, were SARS CoV positive, yet were not counted as SARS related deaths!

Details on these 14 patients would be most interesting.
