I think it is because more people are testing, not that they're getting sick and dying...
My guess on why Ala. has a second wave is because they are law abiding people.They probably sheltered in place longer than most.Knowing that they ironically did little to help their immune system accd. to most doctors we follow.Thereby they were prime candidates for catching what was out there with weakened immune systems.
Mosts reputable doctors will tell you “herd immunity” is what prevents catching the various covid flus that are around.
Cases increased due to more tests. The only number that is consistent is deaths and they are cooking that number. More testing shows more cases but is only revealing cases that would not have been known otherwise due to no symptoms.
SHOUT IT. Testing is valueless except to accentuate the fear and panic.
The number of "cases" will never go down.
