The Covid-19 pandemic, which for over three years has killed millions of people, wreaked economic havoc, and deepened inequalities, no longer constitutes a global health emergency, the WHO said Friday.

It is "with great hope that I declare Covid-19 over as a global health emergency", WHO chief Tedros Adhanom Ghebreyesus told reporters, estimating that the pandemic had killed "at least 20 million" people -- nearly three times the official estimate.
