It is only logical that there will be a sharp increase in community spread after a total lock down. That does not necessarily mean that fatalities will increase. Instead it could be leading to herd immunity.
Personally I’m more concerned about ICU bed utilization. Fewer deaths is wonderful news but increased numbers of people in the hospital for weeks undergoing extremely expensive ICU care and that care being paid for largely by Medicare is going to even further bankrupt us. Current median cost to treat a hospitalized coronavirus patient who recovers is $30,000 nationally
