My health insurance will not cover me in countries under a CDC "no essential travel" advisory. I checked Allianz (Delta offers it with their tickets). They CURRENTLY, policy dependent, will cover you if you get sick while on travel, but no evac - only move you to the nearest hospital, in this case Road Town (or STT if you're "lucky"). Between this and the tracking app, that my colleagues in cyber security told me NOT to download to my phone under any circumstances, I'm out until things change.
