International vacation travels would also be severely hampered by the lack of travel insurance that covers Covid-19 illnesses. As of now, many insurers are excluding coverage for Covid-19 illnesses in their travel products. And if insurers do offer coverage for Covid-19 illnesses, the costs would likely be prohibitive. The majority of the Canadian snowbirders would likely not return to the States (even though they can do so now) until they can obtain travel insurance coverage for Covid-19 illnesses at reasonable costs -- hospital bills could be hundreds of thousands of USD for hospitalizations in any US hospital. Here is what Travel Guard said: "Due to the World Health Organization (WHO) announcement declaring Coronavirus (COVID-19) a pandemic, please note that as of, at the latest, March 11, 2020, COVID-19 is a foreseen event and certain coverages will not apply."
