Hi!
Go and have fun. I'd suggest buying the good quality masks, not the papery fabric kind, which are only good until they get moist, or 20 minutes which ever comes first. And, hard as this might be... stay away from children. (Except your own 
because their germs are family germs). Kids are germ factories. They sneeze and spew secretions and wipe their nose and suck their fingers and everything they touch, they contaminate far more than adults. Their immune system is new and developing. Adults already have years of exposure to bugs with resultant antibodies in their systems, which makes risk of exposure from adults less likely. And this is so true, handwashing is the best protection. Viruses and germs live on surfaces far longer than once believed, so when you go out in public, remember to NOT touch your face or nose, to Sneeze in your Sleeve, and use tissues as a barrier when you need to touch things. Wetness wicks contamination and germs. So avoid damp things and places. Wear flipflops in hotel rooms and showers, wash your hands for 20 seconds under warm water, (cold water chaps your hands and your skin is your body's first barrier against infections), pat dry and use lotion. Avoid hand sanitizers that foam or have alcohol in them as alcohol is very drying, and hence, cracks your skin with frequent use. And, if you hear someone coughing or sneezing, stay >12 feet away from them. Droplet secretions settle out of the air because of gravity by then. Make sure you eat well, and take your vitamins, esp. B, C, and D with you. Good nutrition is one of the best weapons against infections. And don't let yourself get chilled. That is linked to being more susceptible to bugs you may have already been exposed to.

and Happy traveling. I'm sorry if I made you too germaphobic like I am.
