Handwashing is an effective first move in communicable disease prevention!
Early as 1807, an Italian Doctor Guiseppe Alessandro Giannini (1774-1818) introduced isolation, sanitization and handwashing to stop the spread of typhus exanthematicus. This has greatly inspired the way of preventing infectious disease worldwide.

We often unconsciously touch our eyes, nose, and mouth. If we do not wash our hands to keep them clean, we are letting them go into our bodies to infect us! If we do not wash our hands before we consume any food, we will easily get sick from the mouth! If we do not wash our hands, we will easily spread the germs around the environment to infect other people! So, washing hands to keep our hands hygienic and wash away the pathogen is an effective move for preventing communicable disease!
