Days after he shared images of municipal workers disinfecting the streets of Addis Ababa with high-powered hoses, Mayor Takele Uma Banti found himself struggling to explain a 72-hour water shortage. For the 4.8 million residents of Ethiopia’s capital city, interruptions to the water supply are nothing new. But in the grip of a pandemic, the latest disruption threw into sharp relief the inequality created by limited and unpredictable access to clean water. Without a treatment or a vaccine, the primary advice to prevent the spread of the coronavirus is regular hand-washing and good hygiene. But this is out of reach for millions of Ethiopians living without sustainable access to clean water, laying bare the critical link between water and public health.
Water crises were ranked above both infectious diseases and food crises in the World Economic Forum’s latest Global Risks Report. This year, the world is likely to see all three.
In the immediate term, it is essential that clean water reaches as many people as possible to enable them to take the basic precautions needed to reduce the risk of infection from the coronavirus. Improving access to water, sanitation, and hygiene systems could bring down the overall global disease burden by 9 percent and reduce the number of deaths to disease by more than 6 percent. This cannot be achieved when more than 840 million people worldwide currently lack basic supply. In the Arab region alone, for example, more than 74 million people are at greater risk of contracting COVID-19 because they lack the facilities to properly wash their hands. Inequality in water access worldwide will shape the course of the pandemic; it must also be a priority in post-coronavirus economic reconstruction.
