I'm a bit nervous, because I have to travel in 2026 to do book stuff, but I'm now permanently on immunosuppressants (hadlima, specifically). I guess the best thing to do is wear a N95 religiously and try not to let anyone spit in my mouth?
Basically, yeah, and having air filtration for hotel rooms is also a good bet (housekeeping often can't afford to take time off if they're sick, y'know?). This isn't my normal animal blog content but it's important and @pangur-and-grim is a lovely human so we're making an exception here. I also think we should normalize talking about this stuff, so.
I've got wonky immune system problems, although I'm not technically immunosuppressed or on immunosuppressents, but I cannot afford to lose more ground on health stuff so I am extremely careful when I do travel for photography things.
My general rule for travel is to choreograph things as much as possible ahead of time, so I know I'll have safe places for mask breaks. A style of N95 that you're able to wear for long periods and don't worry about the seal breaking is really important. (Multiple styles to avoid ear/face fatigue is a good idea, if you can). Bring more than you think you'll need and always have an extra in your pocket or bag. You can add a sip valve to a mask so you can drink without unmasking if that's within your comfort zone.
My other general habits for travel are keeping hand sanitizer on my keychain at all times, because it's easy to remember when it's bumping against your hip, and bringing a small HEPA filter with me on travel so that I can clear the air in hotel rooms. The latter can feel like overkill for people who aren't high risk for health stuff, but it makes a massive difference mentally to have a space you know has safe air to come back to after a long day around people/crowds. I normally run it in any new space for an hour before I unmask.
A lot of people will recommend various nasal sprays or mouth rinses, and honestly a lot of the "data" for those are based on one or two studies (even if they're decent ones). I've road-tripped with and without over the past few years and didn't really notice a difference. However! One thing there does seem to be good evidence for is that keeping your nasal passages warm/moist helps your immune system; that whole "people get sick when it's cold" appears to be linked to the impact of cold/dry air on the immune regulation inside your face. And they were seeing a difference even at like ... 5C/9F below whatever they used as "room temp". My solution to this has been: if it's chilly outside, I mask up, even if I'm alone, so that I'm not setting myself up to be disadvantaged if my mask seal isn't perfect when I'm around people.
I haven't resumed flying yet for a number of reasons, so I can't comment on airport specific safety stuff, but I'll tap in @kaijutegu because she also is illness-cautious and has flown safely quite a few times. I don't know how Canadian airports handle it, but I do know that the US TSA does require you to unmask quickly when they check your ID, even if you've paid for the pre-check verification stuff. I think basically what people do is hold their breath, put the mask back on, breathe out fully to clear it - like clearing a dive mask, basically.
I wish you super well on your book trip, Greer, and good health <3 Feel free to ping me if you'd like to brainstorm additional respiratory safety stuff. I spend a lot of my travel time at zoos with really germy groups of like, visibly sick children, and camping in my car/using rest stop bathrooms, and I've avoided the ick so far. It can be done.
