“Has anyone seen reliable information regarding the mortality of the Peruvian variant?”
I have not yet.
There is a good chance that Delta could burn through enough more of the unvaccinated, and just not leave enough without immunity behind, before the Peruvian (C.37, Lambda) can get established.
That’s hopeful. I hate to see people have to get immunity that way, but better it would seem with this strain rather than a more dangerous one that could pop up.
