Family member with COVID 19

I have a family member who lives in the Vail valley of the Colorado Rocky mountains, Eagle County to be exact. This area has been designated as a coronavirus hotspot in recent days. Gov of CO is considering closing I70 to prevent people from traveling up to the ski resorts. Vail resort is now closed, mid season. She and my brother in law now have COVID 19 and are at home hoping to get through this without hospitalization. Symptoms began last Wednesday and continue to persist. Body aches and head aches in ways they have never experienced before. Loss of appetite for a couple days. Today both are experiencing sore throats and beginning to cough. She is still working remotely from home, he is recently retired. They attended a friends party of 38 people on Sat. 3/7, 15 of which are now ill with same symptoms. Only 2 have been tested and confirmed.
