Following a rapid spread from its origin in Wuhan, China, the first U.S. case of the 2019 novel coronavirus, which causes a disease known as COVID-19, is confirmed in a man from Washington State on January 20, 2020.

The virus, which would spark a pandemic, was first reported in China on December 31, 2019. Halfway across the world, on January 19, a man who had returned home to Snohomish County, Washington near Seattle on January 15, after traveling to Wuhan, checked into an urgent care clinic after seeing reports about the outbreak.

Dr. Maurice Hilleman was already an expert in viruses and vaccines when a strange flu broke out in Hong Kong in 1957. But only he saw the threat it could pose around the world.

On January 20, the Centers for Disease Control announced that the 35-year-old, who had been experiencing a cough, fever, nausea, and vomiting, had tested positive for COVID-19. He was hospitalized, where his condition grew worse and he developed pneumonia. His symptoms abated 10 days later.

In the following months, the Seattle area became the epicenter of an early U.S. outbreak. 39 residents of Life Care Center, a nursing home in Kirkland, died from complications from the virus in one four-week span. In some cases, people who died from COVID-19 in January 2020, but didn’t know it at the time, had their death certificate amended to show they died from the virus.

According to the CDC, 14 U.S. coronavirus cases were noted by public health agencies between January 21 and February 23, 2020; all patients had traveled to China. The first non-travel case was confirmed in California on February 26, and the first U.S. death was reported on February 29.

As the virus quickly marched across the country, businesses, schools and social gatherings were largely shut down, while, by May, unemployment rates reached their highest levels since the Great Depression.

Spreading to almost every country, more than 662 million people have contracted the virus worldwide, and 6.7 million have died from it. The first U.S. vaccinations for COVID-19 were administered on December 14, 2020. By early 2023, 101 million cases and more than 1 million deaths from the virus had been reported in the U.S. alone.
