Not sure what you are asking, but assuming you want to know if any epidemiological studies were done to find the actual denominator of SARS cases?
Here's one population survey:
CDC: SARS-CoV Antibody Prevalence in All Hong Kong Patient Contacts
If you meant something else, let me know.
I'm talking about Wikipedia numbers. Which are 8,098 cases for SARS. I think this number means number of confirmed cases, who sought medical attention, and does not include antibody study. So it's fair to compare them to Wuhan virus numbers.
