One of the simple strategies implement everywhere in the world to resist the spreading of coronavirus is wash the hands in running water with soap for at least 20 seconds. But in many parts of the world, access to clean water is not guaranteed. According to the WHO/UNICEF 2019, nearly 2.2 billion people of the global population have not access to clean water free from contamination on their premises and 22% of health care facilities have no water service in the least developed countries. As such, water scarcity is a global problem that needs to act on seriously during this urgent time of combating the spread of coronavirus.

Researchers have collective responsibility to communicate evidence of interventions and the expertise to scale up the innovative solutions for protecting water sources with guaranteed access for all.
