My son has been on remicade for almost two years and, so far, I haven't found that it's made a big difference in catching sicknesses. His roommate developed mono last year and was sick for a month before he was diagnosed... even in such close quarters, my son did not get sick.
He did have an extremely bad sunburn this past summer, worse than he's ever had (so I think remicade may have played a part), however, some protection/diligence would have helped avoid the burn! He was at the beach all day but, as it was cloudy, he didn't think he needed suncreen!
He was recently diagnosed with either molloscum or folliculitis. At dx, doctor was fairly certain it was molloscum - however, if this was the case, it cleared up within 4-6 weeks even though all I read was that it usually takes months! His GI did say being immunosuppressed can leave you vulnerable to molloscum, however, it certainly didn't take long for his body to fight it off. (Given how quickly it healed, I'm now thinking it was probably folliculitis.)
Although this is a bit contrary to our experience??, his GI once told us being immunosuppressed doesn't necessarily leave you vulnerable to catching things but you may have a tougher time fighting things off.
