Everywhere suffered a big uptick in cases during that timeframe. Many places in the US peaked in that time frame. I Don’t believe however that the USVI required covid tests 72 hours prior to arriving or any test at all. I think they added that requirement later for some locations including only 10 US states on 15 July. I saw nothing mentioning any issues with tourists. There were quite a few statements on where outbreaks originated in the USVI.
