The increasing polarised and politicised views 1 on whether to wear masks in public during the current COVID-19 crisis hides a bitter truth on the state of contemporary research and the value we pose on clinical evidence to guide our decisions.
This page is updated regularly as new information emerges. It sets out the current Case Fatality Rate (CFR) estimates, the country-specific issues affecting the CFR, and provides a current best estimate of the CFR, and more importantly, the Infection Fatality Rate (IFR).
A majority of U.S. adults say they are taking at least some specific action in their daily lives to protect the environment, though Democrats and Republicans remain at ideological odds over the causes of climate change and the effects of policies to address it.
When did obesity increase? How do rates vary across the world? What is the health impact?
