I got one of them, but also some of my family nephews and brother and others, both daughters and their families. So, yes, I know it exists but I went by no test and only the symptoms though others got the test. No one died or went to the hospital they got medicine and now are fine. I had some problems with breathing but not so much that I couldn't break it up. I do have health problems so, I could be one to say you don't have to always freak out.
