stansgran i think it has all gone quiet for now, but much worry about it crossing to humans at some stage. But this comes into the category of b****er all we can do about it. Just don't snog any birds while you out there. 
You're covered for whatever it says in the policy tegan usually medical care while out there, ship you home dead or alive if you need it. Will not cover you for existing conditions and that is where they will quibble if you make a claim, so I pay a dollop more on my annual insurance because of BP meds. Even though i only go to NZ and AUs, which have reciprocal agreements, I would not be covered if i had a stroke or heart attack in a transit airport - unless i had told them about the BP
Within EU you can get an EU document that allows you to claim treatment under the local systems as per the locals.
I was once refused a claim on travel insurance when my mother died when I was abroad because it was "an existing condition".
