The First 2 Years of COVID-19
On December 31, 2019, the World Health Organization (WHO) Country Office in China reported novel “viral pneumonias of unknown cause” in Wuhan, but China did not confirm case clusters until January 3, 2020. Two years later, more than 285 million cases and 5.4 million deaths have been reported. As of December 2021, more than 800 000 COVID-19 deaths have occurred in the US, surpassing the 675 446 total deaths that occurred during the great influenza pandemic of 1918. The COVID-19 pandemic reduced global economic growth by an estimated 3.2% in 2020, with trade declining by 5.3%; an estimated 75 million people entered extreme poverty, with 80 million more undernourished compared with prepandemic levels.
