Sounds like she caught a cold. What to do? Panic? Scream for help? Go to the police? Or ... tell her to drink lots of liquids and stay in bed for a day or two. Even if she has the Covid, it is not a bad virus. It will keep you feeling like shit for about three days, and afterwards you get a persistent dry cough for a couple of weeks. That's how you know it's Covid (because the government test is fucking worthless).
