Terry,
My son was authorised by the police, the UK government and the Argentinian government to travel.
On his jet leg it took more than 12 hours to get the paperwork done and he was travelling under an existing "allowable" travel mechanism where Argentina allows citizens of another country to travel to an airport which can repatriate them and the person travelling has a booked repatriation flight.
No quarantine was broken, he travelled under the rules and restrictions of the quarantine in place.
The night before he was driven by an American citizen, to the city I flew him out of, through 9 police checkpoints and one Army checkpoint. All checkpoints accepted the repatriation clause and the Embassy documentation.
I am ex military. That means I'm biological warfare trained. Unlike civilians who work outside the sphere of infectious diseases.
No laws, rules or quarantine was broken. My son is not asymptomatic but living in a hostel with 6 other people, many of whom had washed up in a backwater in Argentina, was going to guarantee that he got it eventually.
He has a fair chance of picking it up on the flight back home but it is a risk we must take.
Don't try and scare me here, or paint me as a monster. If I thought I was moving my son, infected, I would not have done it. Whatever the cost to me. But not moving him to a safe place, uninfected, was not an option.
I have no qualms whatsoever, in repeating any of that on the Internet. If it saves someone's life, then fine.
