- Chinese ophthalmologist known for warning about the coronavirus in December 2019
- 45th President of the United States
One year ago, the term "coronavirus" was rarely used outside of medical facilities. Although the virus we would soon learn to call COVID-19 was already spreading in China, it seemed to be a distant issue unlikely to affect Americans. Twelve months, 23 million cases and nearly 400,000 deaths later, the virus has undoubtedly changed life in the United States.
Over the last year, Americans have been urged to stay home rather than go to work or school or meetups with friends. Hundreds of thousands of businesses closed — particularly restaurants, which struggled when they could no longer safely pack in hungry diners. More than 10 million people have lost their jobs and have been unable to find new employment. Hate crimes against Asian-Americans have soared, in part due to President Donald Trump's continued choice to call COVID-19 the "China virus." Among the millions of cases, a small group of survivors known as long-haulers are dealing with lasting symptoms of COVID-19.
Most stunningly, there have been hundreds of thousands of American deaths, a disproportionate number among people of color. Their deaths reverberate through communities, impacting loved ones and the health care workers who pushed to keep them alive.
Here's where this pandemic started, and where we are now:
Dec. 31: China first reports that doctors are treating pneumonia cases of an unknown origin
In late December, Wuhan's government shared that it was seeing dozens of cases of a mysterious illness similar to pneumonia. They believed that the illness may have originated from wet markets in the large city, where vendors sell animals and seafood. At the time, it was believed to be non-transmissible between humans.

Worldwide, there have been at least 92.3 million reported cases of COVID-19 and more than 1.9 million deaths. The best hope now is for the continued effort to vaccinate Americans, though the rollout is going slower than expected. Currently, around 10.3 million Americans have received at least one dose of a COVID-19 vaccine, according to the CDC.
