I have been on Remicade since July and have not gotten sick except for one time, I got a cold that felt like it started to turn into a sinus infection. It held on for more than a month but never got bad enough to go to the hospital for or to even have an antibiotic.
Wash your hands RELIGIOUSLY. Try your hardest not to touch your nose and face. Convince all family memebers of the need to to wash their hands, especially when they first come in after a day spent touching the world. I get my hubby to wash up as soon as he comes in, for one thing, he takes mass transit to commute.
My job as a solo mobile dog groomer gives me minimal contact with people, but I am exposed to various pet bacteria and fungi all day. I just try to be careful as I can be.
