I've been on remicade for 3 years and haven't had any infections or been sick any more than normal. Your immune system is slightly reduced, but still functional on biologics. Everyday cuts and bruises are of no concern. Increases infection risk refers to UTI, Bronchitis, Sinus and similar, all of which require antibiotics to treat. And if you suspect you have one, you're best to seak out treatment early, as it will get worse faster and generally be more severe than a person who isn't on those drugs. Theres some good info on the risks and benefits of biologics on the CCFA website:
