Hi - I’m on Folfirinox regime. I am around my immediate family and stay away from others. We eat take out to limit exposure. The oncology team monitors blood work and toxicity. If your husband’s wbc goes low, the oncologist can boost wbc with a shot in between chemotherapy sessions.
I have noticed that I catch germs others do not - I chalked that up to chemo and cancer both.
I’m not to the post stage yet, but I will ask now that you have mentioned this.
