It's been three years since COVID-19 was officially declared a pandemic. Where were you when it happened? Over 1 million people in the U.S. have died due to the virus. At a time when Americans have largely ditched masks, it’s easy to forget the coronavirus has claimed more lives in this country than its deadliest conflict – an estimated 750,000 died in the Civil War – or previous outbreak. "As a nation, we must not grow numb to such sorrow. To heal, we must remember. We must remain vigilant against this pandemic and do everything we can to save as many lives as possible," said President Biden as the country reached the somber milestone in 2022. We look back at some of the moments that defined and were impacted by the pandemic. 📸 Harrison Hill/USA TODAY, Getty Images #covid19
