I think she is still recovering from the shortness of breath. That seems to take awhile to return to normal, if it ever does. The whole family tested positive. SIL lives next door and they treated two houses as one. After they(MIL/FIL) knew they were exposed, they had a birthday party at MILs house. This was after my wife(a pharmacist at a local hospital) advised that they should stay separate. Needless to say, all tested positive AND had symptoms within 3-4 days. That's 4 adults, 3 children 16 & under. Also the person that initially exposed them also exposed her parents who tested positive. So 1 person took down 6 Adults and 3 children, 2 of which were hospitalized. Her grandfather passed away after contracting COVID while in the hospital. He was not the one who exposed the rest of the family.
