Dr. Jay Bhattacharya – professor of medicine at Stanford University

The issue of the death rate is that we don’t know how many people have actually been infected. The possibility is that millions have already been infected and never even knew they had the virus. If 10 million have been infected, then the death rate is lower then the flu. The key is we have no idea how many people have been infected. The key is to do a survey to find everyone who got the virus, regardless if the have symptoms or not.
