On the down side, the virus may still be damaging tissues in this painless state, which might explain some of those findings of lung and heart damage even in mild or asymptomatic cases.

There is at least one potentially very nice payoff. The finding from the University of Arizona, may lead to the design of whole new painkillers based on the coronavirus spike that is “better than opioids”. The lead author says he has been contacted by people who had […]
