I recently contracted RSV from my baby granddaughter.  I was visiting, she had a cough and a couple of days later, my daughter had her tested and it came back as RSV.  By then, I was sick.  Constant sinus drain and high temps, especially at night.  I didn't get a good night's rest for 10 days.  This then led to immune system inflammation which exhibited symptoms similar to a stroke.  Luckily it was diagnosed as Bell's palsy brought on by nerve inflammation.  I never had Covid, so I can't compare, but you do NOT want to get what I had if you're over 55.  I'm still having sight problems which is why my posting on here has been limited for a couple weeks.
