Hypothetical musings, lots of people seem to have been away this half term lucky things!!
If you got a fever/flu/covid symptoms before you went away I think lots of people would think twice about flying and infecting everyone. Travel insurance would most likely cover this with a drs note.
But what would you do if you got unwell once there? Most insurance won't pay for you to stay longer unless medically necessary. So if it's 'just' a fever would you fly home?
AIBU covid really has changed the way people look at things
