Rapidly Spreading New 'Arcturus' COVID Strain Detected in 20 States

On Jan. 20, 2020, the Centers for Disease Control and Prevention reported the first laboratory-confirmed case of COVID-19 in the U.S. What followed was nearly two years of serious illness, massive death counts, restrictions on movement, massive social readjustment, and sometimes paralyzing fear – all wreaking havoc on everyday life.

COVID-related deaths peaked in the winter of 2021, surpassing the 1918 flu as the deadliest pandemic in American history with more than 1.1 million fatalities due to coronavirus in the U.S. to date. (In 2021, it was the third most common cause of death in the nation, after heart disease and cancer. Here are all the 15 leading causes of death in America.)

Almost everyone, however, is now back to business as usual and living life as if the pandemic is completely over. The John Hopkins Coronavirus Resource Center even stopped collecting data on new cases and deaths more than three weeks ago.

But the coronavirus and its variants are still very much around, and still sometimes resulting in hospitalization and death. And the virus continues to mutate. Last week, the World Health Organization said that it was monitoring a variant dubbed XBB.1.16, or “Arcturus.” This is an Omicron subvariant, similar to the most transmissible COVID variant yet — XBB.1.5,, nicknamed “Kraken.” And if that weren’t enough, a descendant of the new subvariant, XBB.1.16.1, has been detected in several states. (These are alarming outbreaks currently ongoing in the U.S.)

To compile a list of all the states where the new COVID variant has been detected, 24/7 Tempo reviewed data provided by Tableau Public, an American interactive data visualization software company. The table is updated regularly. Population data came from U.S. Census Bureau’s 2022 American Community Survey one-year estimates.

As of the end of March 2023, there have been a total of 195 confirmed cases of the Arcturus variant around America. More cases were being reported every week until week 12 of this year, when cases dropped from 65 to 48 to four. The decline, however, may be due to lack of reporting, not necessarily due to the virus slowing down.
