Risk of infection increases with exposure over time so if you have not already, isolate your daughter in a separate room and mask whenever around her. If it is warm enough where you are, air out the home, if not, use air purifiers. Disinfect commonly touched surfaces. Don’t assume it is too late to avoid infection. I agree with getting an antiviral to have on hand should you start to show symptoms as those need to be taken very quickly to be effective. Also agree with increasing airway clearance. Get enough sleep, eat well, move, preferably outside and keep your immune system buzzing. Hopefully you will get lucky. 🤞
