Bacteria and viruses live on cloths and sponges for hours. Wash your hands thoroughly before eating and after using the restroom. Wash toys frequently with warm, soapy water to kill germs that linger there. When no tissue is available and a sneeze presents itself, sneeze into your shoulder or your elbow as opposed to your hands. This will help to prevent the spread of respiratory fluids via air droplets.
Germs thrive in stagnant air.
Open windows when the weather permits to ventilate rooms. Smoke, a respiratory irritant, increases susceptibility to colds and flu. Always avoid smoking areas. Your hands are a breeding ground for bacteria. Therefore, do not bite or chew on your fingernails.
