I think that students need to get tested for covid-19 with the fast test that are available to the President a day prior to attending the school year and have it repeated often.It's a fact that not every one has a fever that has this virus.Kids that have health issues should be tested first eg.asthma,diabetes,and immune disorders.My nephew has the virus and did not have a fever.He had a runny nose and back pain.The doctor wasn't even going to test him but his mom insisted.You can make an appointment with your child's pediatrician and they should test your child if the schools aren't going to.
