Hi guys,
Came across some information and thought I'd share.
I was on the US consulate's website and they are reporting that people who take the rapid antigen tests at the airport are coming up positive. This applies to unvaccinated people, but as well as asymptomatic vaccinated people.
When you show positive, they immediately detain you. Sometimes for hours and then transport you to a facility, via ambulance, where you will be quarantined for up to 10 days.
This will be done at your expense.

They're not f'ing around, it appears.
