hmmmm...I guess that's a reasonable concern, depending on how nasty/raunchy you think your gear and/or your dressing rooms might be, and how bad your blisters and broken skin are at the moment. Plus we all know some bugs can be pretty nasty these days. The risk is slight, but of course you never know.
Can you get a quick gear clean done? For instance, at one of those places that fog your gear with ozone for 20 minutes (e.g., Sani Sport or Fresh Gear
Fresh Gear - Sports Equipment Cleaning Machines (Hockey, Football, Lacrosse & More!) Your Source for Clean Sports Gear). Those treatments are supposedly good for reducing the nasties in your gear and would probably give you peace of mind.
The other thing to do (whether or not you get your gear cleaned) is
(a) wear a clean layer underneath everything, so your skin doesn't actually touch your gear. I wear underarmour tights and a long-sleeve shirt, plus a pair of thin gloves (they're some sort of breathable liner glove; I've seen another goalie use these scratchy plastic bath gloves from the drug store, and drug stores often sell thin white cotton gloves as well). I do this to keep my gear cleaner, but it can keep your skin cleaner as well.
(b) shower *right* after playing, if you don't already, and do that soap and water thing.
you might also want to think about bringing some extra towels/extra under-layers so you can keep switching to fresh ones when you have a chance, rather than sitting in your own stew, or using a towel that's been sitting in your damp hockey bag all day.
anyway, good luck and have lots of fun if you do choose to play.
