I saw that article, but I also listened (and just relistened) he didn't say PCR. In fact, he first said 24 hours, then he repeated but said 48 hours. The other confusing part is he said "anyone traveling between the BVI and USVI must submit a test within 48 hours of departure" so that can be interpreted several ways. It will be best to see the written rule before worrying too much.

Anyone really interested can interpret for themselves by listening here. You can fast forward to 8:50.
