I'm concerned about my adult daughter. She has had a very bad chest cough for over 5 weeks. She had a chest xray and said no pneumonia..they have doubled her asthma meds but that still not working. They put her on a z pak but still no change. And of course I'm on one coast, she is on the other. Her supervisor has asked that she work from home until this clears but it's not. What should she be doing?
