Dr. Rob Citronberg, Executive Medical Director, infectious disease and prevention, for Advocate Aurora Health, joins the show to give us an update on COVID-19 in the country, and how it relates to sports. How much of the population do they estimate has had the virus so far? Have we caught up with a way to lower the mortality rate? When can we expect a vaccine? When can we expect fans back in the stands at full capacity? How would herd immunity work for the US?
