If you live in a house with other people and one test positive it doesn't matter if the others do or not they count the others as positive. If someone is in a nursing home eating in the dining room with other residents and test positive then the others are counted also as a probable positive. More numbers.
For a covid test CDC says the considered test infection rate is 34 or lower. Kansas set their own standard higher than CDC at 42. So according to the CDC anyone over 34 is not considered infected to the point of requiring treatment. Kansas at 42, is counting a lot more infections, higher numbers, making it sound much worse than what it might be.
I still go and do what I do, wear a mask, wash my hands, and keep my distance. I'm not sure why they are playing this up. So far more than 80% of the deaths are people over 70 with underlying conditions. We do need to take precautions, hopefully a vaccine helps. I don't know, we have the flu vaccine every year and they consider it 50% effective with 40-50K deaths across the US.
Just be smart and be safe.
