I think there is a lot of contradiction surrounding travel at the moment. Airlines seem to be getting back in the air and some countries are opening borders, but the UK home office is still advising against all but essential travel, which I think means travel insurance is invalid. Certainly, I've checked with my annual provider (LV) and they still say any trips booked after March 21st 2020 are not covered for any claims related in any way shape and form to Corona Virus.
Given insurance companies fondness for finding loopholes, I'd suggest they will manage to make any potential claim CV related (Your camera was stolen? The thief may have had Cv so sorry, not covered). So in effect you are traveling with no insurance.
