Hand-washing with soap and water is better than anything else (i.e., hand gel, sanitizer, etc.). Pocket-size hand gel is OK for things like after handling a shopping cart, opening doors, etc UNTIL you can get to a place to wash your hands. Or the pocket-size bottle of bleach/water (for stuff, NOT your hands). Or, a package of sanitizing wipes (not what you get at Wal-Mart, but what you can order from a medical supply place). Me, I wouldn't take gloves. I would just be super anal about hand-washing. I think masks are generally overkill unless you are in an area with a known contagion. If you take a mask, N95s > surgical masks based on the porosity. Again, not a bad item to have, but just have the SA to know when you would need to wear them.
