I was talking about phatguysrule. I’m having the same discussion with him currently.
Okay, here is my very layman explanation.
It doesn't matter which flavor/variant of covid a person has on the local level. For right now, the treatment is the same. Covid attacks the lungs. Medical professionals monitor O2 levels and respond from there.
This is very similar to the flu. Local medical professionals test for the flu and then respond with treatment.
Where variants and different strains in covid and flu are important are tracing the spread and trying to forecast things like personnel and supplies.
Tracking variants is done on a macro level, meaning state or regional labs. Both negative and positive tests are sent to these labs for further testing. Negative tests are done as a control, at first, the Alpha variant was giving a false negative in some tests.
But again, right now whether you have covid or covid delta or covid with extra cheese the treatment for the individual patient is the same.
On locals levels medical professionals recently started seeing an increase in patients testing positive for covid. Based on what we learned last year and what we've learned with things like the flu this was unusual. So the positive covid tests were sent over to state or regional labs for further tests. Further tests showed there was a variant. As those tests came in around the country more and more of those tests tested positive for the delta variant.
With those results, we could see, based on the percentage of these additional tests, how the delta variant was spreading.
It is this same process that will detect that next variant.
You're asking why we don't have a covid test on the local level that detects the delta variant. That's because it's not needed. Again, it makes no difference in how a patient is treated.
