Very interesting.
The "entry protocols" document posted at
https://www.bvitourism.com/reopening states:
"2. Obtain a Certified RT-PCR SARS-CoV-2 negative test result 5 days before arrival and submit it on the App. Sampling must be nasopharyngeal and in the case of children 5 to 9 years old oropharyngeal. Children under age 5 will only be tested if medically indicated."
They still have a lot of coordination to do with these protocols.
