Praying that Faith will be checked out negative for COVID-19!
But the most important is the home got to be sanitized at the moment and she would need to wear mask and quarantine herself from everyone for a short time.
The important part is to know that flu is actually deadlier than COVID19 in the States so but the spread is faster. As long as everyone is keeping personal hygiene well the risk can be lowered a lot.
Wishing her well and praying for her
(+ lots of vitamin c!)
