Do not share razors. Line your trash cans and waste baskets and empty them frequently. Wash hands frequently and then apply lotion. You do not need an antibacterial soap. Friction rubbing and washing does the greater part of cleansing.
Lotions often provide good barrier protection against disease.
Inexpensive lotions work just as well as expensive lotions to protect skin. Avoid touching or rubbing eyes, do not scratch. These actions introduce eager invaders to the body. Use tissue instead of handkerchiefs. Use paper towels when possible.
