Frequent handwashing helps reduce the spread of germs and prevent illness, even when your hands do not look dirty.
Touching a contaminated object and then your body can transfer germs; hands can also spread them through shared objects or handshakes.
Wash after using the toilet, coughing, sneezing, or blowing your nose, and before eating or preparing food.
Use cool or warm running water, apply soap, and lather for at least 20 seconds to lift dirt and germs.
Rub between fingers, the backs of your hands and fingers, thumbs, nails, and cuticles before rinsing well under running water.
After rinsing, turn off the tap and dry your hands with a clean towel or let them air dry.
If soap and water are unavailable, use sanitizer with at least 60% alcohol, rubbing it over your hands until dry.
