GRAND RAPIDS, Mich. — It's hard to believe that it has been two years since the coronavirus pandemic reached the shores of the United States.

To some, it feels like the pandemic has dragged on for decades, and to others it might feel like the pandemic has only been a blip on the radar.

Thursday, Jan. 20 marks two years since the first COVID-19 case was confirmed in the United States. In December 2019, a pneumonia outbreak of unknown causes was announced in Wuhan, China, which epidemiologists would later realize is a new highly contagious novel coronavirus.

In January 2020, the World Health Organization and Chinese authorities scrambled to understand the cause of the pneumonia outbreak. And by the end of the month the virus had already began traversing the globe and showing up in dozens of countries.

The new novel coronavirus first reached the United States on Jan. 17 when a Washington state resident was reported to have contracted the virus. On Jan. 20, the case was confirmed to be the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or COVID-19.

It would be almost two months before the first reported case COVID-19 was reported in Michigan on March 10, 2020. Over the next 22 months, Michigan would report over 1.8 million COVID-19 cases and nearly 29,000 deaths related to the virus.

The virus has come in waves throughout the pandemic and various mutations like delta and omicron have caused these waves to be much larger than at the beginning of the pandemic.

Michigan is currently experiencing some of its highest hospitalizations and rate of infection since the beginning of the pandemic.
