World Health Organization. Water, sanitation, hygiene (WASH) and waste management for the prevention of COVID-19: Updated Technical Note - 2nd Edition (2020)



"On 30 January 2020, WHO announced that the COVID-19 outbreak was a Public Health Emergency of International Concern. Initially, most cases were reported from China and among individuals with travel history to China. COVID-19 is an acute respiratory illness caused by a novel human coronavirus (SARS-CoV-2, called COVID-19 virus), which causes higher mortality in people aged ≥60 years and in people with underling medical conditions such as cardiovascular disease, chronic respiratory disease, diabetes and cancer. In response, WHO has published a number of technical guidance documents on specific topics, including infection prevention and control (IPC). 

This technical brief supplements those IPC documents by referencing and summarizing the WHO guidance on water, sanitation, hygiene and health care waste that is relevant to contain and inactivate viruses, including coronaviruses. This technical brief is written, in particular, for water and sanitation practitioners and providers. It is also for health care providers who want to know more about water, sanitation and hygiene (WASH) risks and practices." - WHO, 2020.
