As of January 26, there's been a
CDC requirement that all passengers (vaccinated or not) entering the U.S. show proof of a negative result from a COVID test taken within three days of arrival. The test can be either a PCR or rapid/antigen test, and in most Caribbean destinations resorts are offering guests rapid testing on-site, some at no charge. The BVI, however, only offers PCR testing for these purposes, and charges $70. Resorts here are not authorized to offer testing on-site unless guests have chosen the territory's official concierge service, which, for resort-based visitors, costs $400 for physician's fees plus a $200 transportation fee and a service charge of $75 in addition to the testing fees. Most visitors end up having to test at a nearby hospital or clinic (I did mine at Virgin Gorda's Peebles Hospital) so be sure to budget for taxis in addition to testing fees.
