The Netherlands wants to introduce a mandatory quarantine for all travelers from high-risk areas from 15 May. Also from Aruba, Bonaire and Curaçao. Now that quarantine is still an advice and not mandatory. Research shows that few returning travelers adhere to the advice. It concerns ten days and with a negative test five days of compulsory quarantine. For violations, fines of 95 euros are awarded. Sint Maarten, Saba and Sint Eustatius are on the list of safe countries.
