This sounds like a good idea on the surface, but from a practicality stand point I don't believe this will work. And, for how long of a period would they intend to do this for? Testing asymptomatic people in advance will be a waste of these tests that can be better used on symptomatic residents and visitors on the island. Presenting a negative test in advance might work, but a person could be infected in the time between their test and their arrival on St. Martin. I would propose temperature checks at all airports flying to St. Martin and follow-up temperature checks at PJIA. If a temperature greater than 99.5 Fahrenheit is recorded, then the possibility of a rapid COVID-19 test could be administered. Eventually, once a vaccine is available officials could and probably should require proof of vaccination in advance of arrival on SXM.
