The chronology of Covid will be studied for decades to come. It shows how the exponential spread of a virus can go unchecked until it’s too late. It shows who paid attention, and who didn’t. It shows what worked, and what served only to delay the pain or make it worse. The day-by-day sequence of events reveals astonishing stories, like the weekend it took Moderna to create a vaccine, and heartbreaking hesitation, like the two weeks Britain waited before locking down. So, for day three of our file on the findings of our Covid Inquiry, we’ve laid out that sequence to let it speak for itself.
