The “Delta Variant” may be more infectious but is also milder and less deadly.*
* According to what little data is available. (Which appears to be a deliberate situation)
That is the USUAL case.
I hope it’s still true here.
It’s as if viruses play a balancing act. If they infect easily, that is enough for them to survive and the fatality rate isn’t high.
But if they can’t infect easily, they tend to be very powerful and deadly. They’re making up for their deficiency that way.
E.g, in honesty COVID has no more than 1% death rate. Its cousins, like MERS and SARS, have something like 30% and 11% death.
