The COVID-19 Pandemic
On the timeline · around 2020 ·
What happened
In early 2020 the novel coronavirus spread across the United States, and in March the country locked down. Over the following years COVID-19 killed more than a million Americans, upended the economy and daily life, and prompted a record-fast development of vaccines.
Why it matters
The pandemic was the deadliest public-health crisis in a century, transformed how Americans work and learn, and became deeply politicized — a defining, divisive event of the era.
