Good luck with your farmhouse restoration work Charlie .... lucky you, that you have such a wonderful escape valve available ..... think of it as a bachelor's vacation!
Sorry to hear that this vector is headed your way, but third world connections are always a roll of the dice in so many ways.
If it makes you feel better to quarantine yourself, then that is all the reason you need to go ahead and do it. The many hours flight in the closed circulation of the aluminum tube, is likely your daughters greatest chance at exposure, but getting home soon may well be her best bet, as it is problematic how much longer airlines can operate under the current paradigm. Personally, I think (or at least hope) that this issue will not be nearly as bad as advertised here in the first world, but there is absolutely nothing wrong with taking every reasonable precaution that you can think up.
Truly hope everything works out for the best for you and your family there Charlie!!!
