I keep reading that there is no test for “Delta variant”. I believe what we are seeing is just plain covid in these “breakthrough” cases. They can’t let people know that the fake vaccines are failing so they came up with a “variant” to blame it on.
You keep reading the same people that refuse to have it explained. A sample quantity of positive COVID tests are examine using genetic sequencing. This reveals the strain. Simple statistics tells what percentage of all positive tests is that strain.
The original "plain" COVID is extinct, replaced by later strains. As are some of the earlier strains.
No one is asking what happened to Alpha, Betta, Gamma, Delta, Delta Plus, Kappa, Lambda, and now they’ve discovered Mu here in Ohio! Curiouser and curiouser….
