SARS-CoV-2 was identified in late 2019 and declared a pandemic by the WHO in March 2020. Reported deaths total roughly 7 million, while excess mortality analyses estimate the true toll at 18 to 27 million.
The response produced the fastest vaccine development in history, with multiple effective vaccines authorised within a year, alongside unprecedented economic disruption, school closures affecting well over a billion children, and sharp debates over restrictions, equity and misinformation.
The WHO ended the global emergency declaration in May 2023. The pandemic reshaped public health surveillance, remote work, supply chains and pandemic preparedness policy worldwide.
