5 of 8 my immediate family members have had Covid and recovered in a couple of days.
Not pleasant. But, treat the symptoms. Stay hydrated. If fever breaks 100 or difficulty breathing get to ER. Monitor O2 levels to remain above 90% if you can.
Disclaimer. I am not a doctor or expert. I am just someone that has watched family members efforts to overcome the virus.
My prayers for your mom.
May I ask about the other 3?
