If you are using hand sanitizer right now, please remember to wipe down your phone a couple times a day as well. And if you're about to eat, make sure you've washed your hands.

Edit: if you can't afford to buy sanitizer for everyone, take a few minutes to make it. Mix 1/3 alcohol with 2/3 aloe or baby lotion and put it in the extra plastic bags or bottles laying around. You can keep it in your car, backpack, desk, anywhere really
