Testing should be done for people who are going to work and interacting with lots of people! Nurses, grocery store workers, delivery people!!! Testing every couple days for these people!!!My wife's friend has a kid who has a bad sore throat and has difficulty breathing. They gave him some meds for his symptoms but did not order a test and then just sent him home.
If you think about it, there's really no need to do Coronavirus testing for anyone who is not old, and/or doesn't have an underlying condition. Whether you have it or not, all they'll do is tell you what to do for your symptoms and tell you to stay at home.
