“ Evacuees will likely arrive first at Travis Air Force Base near Sacramento, Calif., where they will undergo additional health screenings, said Dr. Walke. Some will likely remain at Travis to undergo a mandatory quarantine, which will likely be 14 days, he said. Others may be moved to Lackland Air Force Base in San Antonio to quarantine.”
Looks like it will be 14 days.
OK

I pulled 28 days out of a hat :)
