When a virus is so weak, as this one is, I believe testing is irrelevant. It only feeds hysteria that infection is to be feared, which this one should not. No covid should, in my opinion, when compared to other common respiratory illnesses, which have roughly the same symptoms.
When I pressed my sister on why she got tested, she said because she wanted to be able to compare how ill she actually became, if it was covid, as it turned out to be.
She said in the end, it was an extremely mild experience. She only had a slight fever, Friday morning, and picked up the test at her pharmacy drive through. After testing positive, she stayed home from work of course. The mild fever broke that day, and by Sunday she was perfectly fine.
That doesn’t mean everyone infected may have such mild symptoms. But it convinced her to never waste her time and money or the risks on ever being tested again.
Testing is important due to the risk of infecting other people. COVID still kills people and makes others very sick sometimes with long lasting symptoms. One of the reasons it does not go away is because contagious people are out there infecting others.
Testing and quarantining if positive is a decent thing to do for other’s benefit, especially if you might interact with people who are at risk for more serious outcomes.
