Make sure her fever doesn't get over 103. Keep it under 101, ideally, by alternating Tylenol and Motrin. In terms of dosage, Tylenol is worse over time (e.g., taking it for weeks), but not a huge risk in the acute sense. Motrin is more of an acute risk (don't take too many at once) and less of a risk over time. Have her drink 8oz (half a glass) of water every couple hours, and a few ounces of Pedialyte every couple hours. No matter what she says about not feeling like drinking anymore, make sure you keep her on this regiment. Have her go outside to get sunlight for at least 15 minutes with good exposure (e.g., with a tank top and shorts) or 45 minutes with minimal exposure (e.g. long sleeve shirt and pants, where it's just hands and face in the sun). Take vitamin D once per day and vitamin C 3 times. Make sure she's getting good long sleep at night but not just lounging all day; at least some physical activity helps keep things running. If you have N-Acetylcysteine (NAC), have her take one per day, for up to a week, until better. Any kind of serious symptoms (difficulty breathing, persistent dizziness, etc.), take seriously. COVID-19 is fake, but pneumonia is not. Neither is the flu, but she should be fine. Disclaimer: none of this is medical advice, it's all just entertainment and personal opinion.
