I, too, have become an expert on travel insurance lately. We had to cancel two big trips, one to Italy and one to Portugal. In the absence of a cancer diagnosis, our insurance would not even have paid for our canceled trips since it exempted the pandemic from covered causes.
We are fortunately retired so it has been fairly easy to isolate and order everything we need online. We've also been doing video appointments with doctors to the extent possible. That said, going out for medical tests has been challenging and we're not looking forward to my husband having to go out for treatment soon.
