> Pretty sure the fatality rate is based on the number of patients who present themselves to a doctor. In an ideal world that would be true, however we know that in early Wuhan they were mostly only testing people who were already hospitalized with "pneumonia symptoms" due to having limited kits and staff. Pneumonia symptoms how the most serious cases advance after going through flu symptoms. I read one analysis of the Wuhan data that showed 91% of everyone they tested had pneumonia. This changed later but a lot of the stats we're looking at are from papers with data only through the end of Jan. Almost every country has different criteria for testing a patient and you can't become a "case" until you have a positive test. The U.S. has changed testing policy three times in the last week.
