Statement by the European Public Health Association (EUPHA) on combatting COVID-19: the importance of sharing knowledge to create a comprehensive and publicly available evidence-base

The COVID-19 outbreak is affecting everyone worldwide, and policymakers, scientists and practitioners are exploring uncharted territory while trying to get to grips with this new virus. Especially in such times of great uncertainty, building on up-to-date and accurate information is crucial. Robust systems of epidemic intelligence that can provide solid national and regional-level epidemiological data to inform modelling of disease transmission at the population level, and ultimately offer effective guidance on public health action, are needed. Sharing data, research outcomes and experiences in order to build a common, growing body of intelligence is key when battling the outbreak and saving lives. Indeed, we see many examples of information being shared, across disciplinary, sectoral and geographical borders, contributing to new insights and accelerated generation of knowledge. EUPHA, as a science-based organisation, commends this open attitude, and calls upon all relevant authorities, organisations and experts to share evidence to the maximum extent possible.
