And to be thorough in the “medivac” discussion, medical “evacuation” simply means IF you are seriously ill or injured, AND the insurer’s medical team, along with the local doctor determines that the local medical facilities are unable to provide adequate care, the insurer will pay to transport you to the nearest appropriate medical facility (that they identify). Not to your home or local hospital.

Medical “repatriation” is, per our insurer’s description:
“If you are seriously ill or injured AND under the care of a local doctor and unable to continue Your Trip, medical repatriation takes place once Our medical team determines that You are medically stable to return home via commercial transportation carrier, such as a scheduled passenger airline.”
So if diagnosed with COVID-19 repatriation would not take place via a commercial flight until no longer considered a risk to others...

Other policies are probably worded similarly, I see that Medjet has isolation pods in aircraft for COVID-19 and other infectious diseases. Hiwever, for international destinations Medjet will not transport you to your home hospital until you are deemed clear...
