The year 2020 was unprecedented in many ways, one of which was the tremendous attention given to appropriate hand hygiene practices in the fight against SARS-CoV-2. Hand hygiene has finally gained global recognition from policy-makers, health managers, health care workers and the general public as a keystone in infection prevention. The World Health Organization (WHO) placed increased focus on hand hygiene in the context of the global COVID-19 pandemic, in addition to its longstanding efforts through both the global SAVE LIVES: Clean Your Hands campaign and the Water, Sanitation and Hygiene (WASH) Programme. In the context of the pandemic WHO launched several initiatives, including the new WHO and UNICEF Hand Hygiene for All initiative (https ://www.who.int/ water _sanit ation _healt h/sanit ation -waste /sanit ation / hand-hygie ne-for-all/en/) to consistently improve hand hygiene practices as a whole-of-society approach to stop the spread of SARS-CoV-2 and sustain good practices beyond the pandemic. To achieve these goals, adequate infrastructures should be provided in health care and public settings, including for example schools and public transportations, and appropriate behaviour to clean hands when needed should be taken by all key players. This year, WHO’s SAVE LIVES: Clean Your Hands campaign focuses on achieving appropriate hand hygiene

The year 2020 was unprecedented in many ways, one of which was the tremendous attention given to appropriate hand hygiene practices in the fight against SARS-CoV-2. Hand hygiene has finally gained global recognition from policy-makers, health managers, health care workers and the general public as a keystone in infection prevention. The World Health Organization (WHO) placed increased focus on hand hygiene in the context of the global COVID-19 pandemic, in addition to its longstanding efforts through both the global SAVE LIVES: Clean Your Hands campaign and the Water, Sanitation and Hygiene (WASH) Programme.
In the context of the pandemic WHO launched several initiatives, including the new WHO and UNICEF Hand Hygiene for All initiative (https ://www.who.int/ water _sanit ation _healt h/sanit ation -waste /sanit ation / hand-hygie ne-for-all/en/) to consistently improve hand hygiene practices as a whole-of-society approach to stop the spread of SARS-CoV-2 and sustain good practices beyond the pandemic. To achieve these goals, adequate infrastructures should be provided in health care and public settings, including for example schools and public transportations, and appropriate behaviour to clean hands when needed should be taken by all key players.
This  for many years, but is now more critical than ever. Furthermore, 2021 has been designated the International Year of Health and Care Workers (https ://www.who. int/campa igns/annua l-theme /year-of-healt h-and-careworke rs-2021): focusing on their protection is also paramount.
The first prerequisite for effective implementation of hand hygiene action at the point of care is "system change" meaning that the appropriate infrastructure and supplies should be available at the point of care so that health workers can clean their hands promptly when needed. This requires reliable and uninterrupted provision of good-quality alcohol-based handrub (ABHR), supplies of clean water, soap, single-use towels and an adequate number of functioning sinks. Although effective infection prevention and control (IPC) programmes in health care facilities should meet WHO minimum requirements [1], the 2020 global WASH report revealed that one in three facilities do not have adequate hand hygiene stations at the point of care [2]. A recent systematic review showed that hand hygiene compliance is only around 9% during care of critically ill patients in lowincome countries [3]; such shocking data, in conjunction with the ongoing COVID-19 pandemic, highlight the urgent need for additional efforts to strengthen global compliance and champion best practices. Although vaccines are starting to be delivered, hand hygiene and appropriate use of personal protective equipment remain crucial for safe care of both COVID-19 and non-COVID-19 patients.
Effective hand hygiene not only reduces the burden of health care-associated infections and the spread of antimicrobial resistance but is also a key IPC measure for safe COVID-19 vaccination [4]. ABHR is the preferred method for hand hygiene in health care as it can be easily accessible at the point of care, kills microorganisms quickly (within 20-30 s) and is well tolerated by the skin. These advantages can help to overcome behavioural barriers to compliance. In the light of current shortages, many countries have successfully established local ABHR production as a low-cost alternative within facilities, using WHO-recommended formulations [5].
To highlight the urgent need to save lives by implementing best practices in health care delivery, the slogan for 5 May 2021 is "Seconds save lives-clean your hands" (Fig. 1). The WHO campaign calls to action key stakeholders (Table 1) who can play critical roles in achieving optimal hand hygiene at the point of care, in both the current situation and a broader sense, helping to strengthen society involvement as promoted by the Hand Hygiene for All initiative.
