Until there is a vaccine or cure for Covid-19, prevention remains the only option. And even with a cure, prevention will remain the better option. Water, sanitation and hygiene (WASH), together with physical distancing, are central to preventing the spread of the coronavirus, and are a first line of defence. That is why Sanitation and Water for All (SWA) has launched the ‘GlobalCall4Water’ initiative which states that ‘As leaders, this is our chance to save lives’. Dozens of heads of state, ministers, CEOs and leaders of UN agencies and other international organisations have joined this call to action. Robert Bos, Chair of the Supervisory Board at IRC, signatory organisation of the call, and Pim van der Male, Senior Policy Officer WASH at the Dutch Ministry of Foreign Affairs, tell us about this initiative and the importance of WASH.
