About the Delta variant, the claim, by some, is it is more transmissible, but is it more deadly? Same question for this Lambda variant. I'm not finding lots of data on mortality of Delta or Lambda vs the baseline.
One expert* says this:
"So far we have seen no indication that the lambda variant is more aggressive," Jairo Mendez-Rico, a WHO virologist,
told the Deutsche Welle. "It is possible that it may exhibit higher infection rates, but we don't yet have enough reliable data to compare it to gamma or delta." He told the German outlet that
as SARS-CoV-2 evolves, it may start to become more transmissible, but not as deadly. (<-- that is the usual 'flight path' of most viruses.)
*My two favorite engineering definitions of "expert":
- anyone from more than 40 miles away, because if they drove that far they must know more than us, or
- X is the unknown factor, and spurt is a drip under pressure --> X-spurt.
