“The scientific evidence overwhelmingly demonstrates that appropriate hand hygiene is the single most effective action to stop the spread of infection, while integrated with other critical measures.

• • Appropriate hand hygiene prevents up to 50% of avoidable infections acquired during health care delivery, including those affecting the health work force.
  • The WHO multimodal hand hygiene improvement strategy has proved to be highly effective, leading to a significant improvement in key hand hygiene indicators, a reduction in health care-associated infections (HAIs) and antimicrobial resistance, and substantially helping to stop outbreaks.
  • Appropriate hand hygiene reduces the risk on SARS-CoV-2 – the virus that causes COVID-19 – infection among health workers.
  • Investing in hand hygiene yields huge returns. Implementation of hand hygiene policies can generate economic savings averaging 16 times the cost of their implementation.

Hand hygiene compliance is recommended as one of the key performance indicators for infection prevention and control programmes, patient safety and quality of health services worldwide.”
