I think it depends largely on what his oncologist thinks. I have had CLL for 15 years. Last year was the first time I needed treatment. I had 4 infusions of Rituximab and it seemed to work well. My 2.5cm ca did not appear in the pet scan post treatment. That’s a little history. Now, about travel, I’ve been traveling out of the US for the past 5 years. I go to the Virgin Islands for business and a break. I take along antibiotics for things like a possible urinary tract infections, and also, those needed for infections from cuts or similar injuries. In addition, I bring regular meds (mine are few, just my BP pills and a prescription Iron supplement). I do carry OTC meds in my luggage (to avoid looking for an alka seltzer or Tylenol etc. at 3:am or some other inconvenient hour). I am very cautious and mask in appropriate situations. To spite this, somehow, I managed to catch Covid-19 appearing just days after my last trip. I am on my 3rd day of Paxlovid. It began with a dry cough, extreme tiredness, then a constant cough, very bad sore throat (unlike others I’ve had), headache, difficulty sleeping, joint pain and so on. I am still going through a tremendous amount of discomfort. My point in telling you all of this is to remind you that CLL means a COMPROMISED IMMUNE SYSTEM. Travel is fine as long as you are prepared and think ahead. Where you travel to is another issue entirely. If it was me, I’d avoid having to sit next to a stranger if not necessary. The plane trip is usually the unavoidable place, but I’d mask in the airport as well as on the plane. I’d also request early boarding. Just ask at the terminal desk where you will board. It’s never been a problem. Early boarding just keeps me out of the crowded
isles and the push in general boarding. I am seated with luggage placed above before the onslaught of passengers. You can accompany your husband on the early boarding call. I also am last to leave the plane unless we are seated very close to the front. Make it a point to avoid crowed restaurants and general areas of entertainment. Prior to Covid, this extreme caution wasn’t an issue (except in flu season etc.). Check with restaurants for their least crowded hours. You don’t have to give up travel because of CLL. You just have to accept the limitations put on us by Covid, flu season etc. Normally, I would not be so wordy, however CLL is a depressing and life changing diagnosis. To be able to continue to travel and have enjoyment makes it far easier to deal with. I believe I became overconfident and relaxed my cautions on this last trip. I am very tired, hurting and really uncomfortable, thus, I’m actually dictating this to my masked husband 10’ away. I felt it was important to share all this and pay it forward. Someone did it for me. Good luck and stay positive as hard as it may seem at times. He may never need any treatment, he just needs to be aware of his limitations. That is a rough one as people are stubborn when challenged by a quiet illness. The temptation is to ignore it, but Don’t.
