Key facts

  • Hand washing is one of the most cost-effective public health interventions for preventing the spread of infectious illnesses.
  • Each year, about 3.5 million children die before their 5th birthday due to preventable diseases, mainly diarrhea and acute respiratory diseases. 
  • According to survey data from the Global School-based Student Health Survey (GSHS), over 15% of schoolchildren in some countries say they rarely or never wash their hands before eating.

The simple habit of washing hands with soap and water at critical times—especially before eating or preparing food and after using the toilet—can prevent nearly half of deaths from diarrhea and almost one-fourth of deaths from acute respiratory diseases. Hand washing promotion in schools plays a role in reducing absenteeism among primary school children.

The Region of the Americas set a new Guinness World Record in 2011 for the most people washing their hands simultaneously in multiple locations. Representatives from Guinness certified that on 14 October, 740,870 people washed their hands simultaneously in different locations in the Americas, including 604,246 people in Peru, 134,790 in Mexico, and 1,834 in Argentina.
