Try getting home when all flights are cancelled for months
If it is a pandemic, then all tourism will be shut down and probably flights will be very restricted (with a lovely long stay in a quarantine facility on arrival). An individual couldn’t predict the timing of that.
I wouldn’t want to be overseas if travel is mostly shut down: unless you happen to be in a country with better services. I’m in NZ and have enough food/water/medicine to let me hunker down at home for a few weeks. I am also lucky enough to have options to move to rural locations: hospitals won’t be able to help much if a pandemic peaks quickly...
