Daily new cases of the coronavirus have been on a sustained decline since the end of July, according to data compiled by Johns Hopkins University. Deaths, which lag behind new cases as people fall ill, become hospitalized and die, have remained stubbornly high, at roughly 1,000 new Covid-19 deaths per day, on average, according to a CNBC analysis of Hopkins data. “I think we’re going to start to see a decline in mortality across the country now next week as we continue to get control of these cases,” Director of the CDC Dr. Robert Redfield said Thursday.
