I saw something on one of the BVI Abroad Facebook page recently posted and saved it. Having not traveled there yet I cannot vouch for it but thought I would share it.
www.auraassistance.comApparently they are approved by the Gov of the VI. Price is 9.75 USD a day and seems pretty comprehensive.
While my health insc. covers me globally and for Covid (with lots of phone calls for approval of services for anything major), for 9.75 a day I would think about using this. My thought is that if its approved by the Government and I need medical assistance it may be easier to have that than deal w my heath insc. company.
