wow, they are going to start cleaning planes instead of landing, offboarding and boarding with a 1 minute turnaround.
I used to automatically get a cold or respiratory infection after flying, but theyre doing a much better job on air scrubbing now and its been about four or five years since that has been a problem. But I only fly the major US airlines, mostly Delta, which does an excellent job.
The thing I think is most like to be a problem is contact with surfaces, so just bring some wipes and wipe off your tray table and arm rests, as well as any lavatory surfaces...and then give your self a hand-sanitizer treatment. I have seen a lot of people doing this for years, actually, and its a good idea. That said, most viruses die pretty quickly away from their host. But theres a lot of other things out there, such as e-coli, that you can get from touching something. And never touch your face! LOL!
