You can pick up a “nasty cold”, flu, covid, d&v etc literally everywhere you go where there’s people. People go about their daily lives with colds, they’re a bit annoying and you can feel a bit crap, but people would never go to work if they were catching colds all the time, like from their children. How would eg teachers, esp of younger children, manage to not go in to work every time the caught a bug? Someone who had a bit of a cold but feels well in themselves and is able to carry on their daily life shouldn’t have to lose potentially thousands of pounds on a holiday just in case anyone catches it? Why should your holiday trumps theirs anyway? I mean yeah, I would be a bit annoyed at sitting next to someone with a cold but the virus is everywhere particularly at this time of year. If you choose to go on a flight, you accept that there may possibly be a minuscule risk of something like that. If you’re worried enough about the recirculating air then don’t fly.
Im pretty certain if I put up a poll of times people have actually caught something on a plane vs number of flights taken, or total number of flights all posters have taken, the results would show that the risk was an extremely small number - and would be probably be so low as to be statistically insignificant (not that I would actually sit here doing equations just to prove it!). The results would be easy enough to see. But in reality One person may have taken 100 flights and never got ill, one person may only have ever taken one flight and been unlucky.
Where im in agreement with, in these following cases I don’t think people should really go anywhere where there are big, physically close groups of people that you will be in contact with for an extended period (especially in inclosed spaces, not just flights, but weddings etc) who knowingly have covid, flu, ACTIVE v&d, or strong signs of, which the op doesn’t have atm, and she wouldn’t want to go if she did, that’s quite clear. But yes, people who do that are selfish. Although if someone had actual flu they’d not even be able to get on a flight, so chances of that would be lower, otherwise it’s just a cold. But you run the risk of literally anyone on that plane being completely asymptomatic, but still infectious, and you or they would have no clue, so if you are that worried about it, even just for a cold, then just don’t be in those places because anyone could have something and not know 🤷🏼♀️ people can’t just stop their lives because they have a cold.
Ironically I’m sat here with a cold. So sorry if it’s all a bit of a word salad, I’ve tried making it make more sense but I am feeling rufffff 🐶 My first viral infection of any kind (including Covid) in over 6 years. I’m also classed as immunosuppressed, btw, but I’d still have to accept that small risk if I wanted to fly. Or when I do have to go places where there will be other people.
