The American lung association is lying lol?!Just rumor.
The actual facts are that covid has an infection rate R0=2 while the delta variant has an infection rate R0=2.5,
And it is not more deadly, but less deadly.
There is no risk of overwhelming health care systems and never has been.
The whole reason the deaths keep increasing and the virus has time to produce variants is that we "flattened the curve".
You should never do that.
The quicker you end the virus through recovery, the fewer deaths you have.
