The COVID-19 Hygiene Hub communicates a diverse range of resources and learning developed during the pandemic, which has provided critical support to COVID-19 response efforts around the world. This COVID-19 Hygiene Hub platform has three principal functions: • to connect institutions and organisations implementing hygiene programmes in response to COVID-19 with technical advisors who can answer questions and provide detailed advice in real time • to provide access to a searchable set of resources which summarise current evidence and guidelines and make practical recommendations for crisis-affected or LMIC settings • to offer a platform for sharing what is working among governments, international organisations, and civil society actors. We bring together technical advisors and resources, governments, international agencies, and NGOs for effective hygiene programming. The COVID-19 Hygiene Hub is a broad partnership housed at the London School of Hygiene & Tropical Medicine (LSHTM) that draws on scientific, operational, and creative expertise from a network of organisations. This initiative was developed by individuals from LSHTM, the Centre for Affordable Water and Sanitation Technology (CAWST), and the Wash’Em team. The strategic direction of the COVID-19 Hygiene Hub will be guided by leading international agencies to ensure it remains responsive and adaptive to the changing nature of the pandemic. The strategic direction of the COVID-19 Hygiene Hub is guided by a steering committee comprising senior representatives of leading international agencies, including the World Health Organization (WHO), the World Bank, UNICEF, the Global WASH Cluster, the International Federation of the Red Cross (IFRC), WaterAid, Oxfam, and Action contre la Faim (ACF). The Hygiene Hub is funded by the government of the UK - DFID and the Bill & Melinda Gates Foundation. The views expressed do not necessarily reflect the UK government’s official position.
