Anyone know what states are forcing those who fly in to be quarantined for 14 days?

My husband and I live in Alaska and are due at the end of July. We have family from Virginia who have had plane tickets since before the coronavirus happened, to fly out from VA to AK for the birth in late July.

If they still fly out, will they be forced to quarantine and not leave our place for 14 days? Does anyone know where I can find out this information?
