According to data from the New York Times as of Tuesday, Alaska, Idaho, Kentucky, Minnesota, Montana, Tennessee, Washington, and Wyoming, have seen an increase in daily COVID-19 case average compared to 14 days ago.

Alaska has a daily average of 2,268 new cases, a rise of 20 percent from the daily average from two weeks ago. Idaho has seen its average daily cases soar to 4,983, 43 percent higher than they were on January 18.

Kentucky saw its daily average of new coronavirus cases rise to 10,825 on February 1, spiking 49 percent compared to two weeks ago.

Minnesota recorded a daily average case number of 13,188 on Tuesday, a rise of 24 percent compared to 14 days ago. Montana saw a rise of 61 percent, recording 2,161 average daily cases on February 1.

Tennessee recorded an average daily case load of 15,510, 11 percent more than two weeks before. Washington’s average daily case number is 18,744, 18 percent more than 14 days ago.

Wyoming saw a 31 percent increase in its average daily COVID-19 case number compared to two weeks ago, recording this number as 1,233 on Tuesday.

States that were hit early by the highly-transmissible Omicron variant are seeing some of the steepest drop-offs. For example, New York state saw a 73 percent fall in average daily cases on Tuesday compared to January 18.

Nationally, the U.S. recorded an average daily case load of 456,871 on Tuesday, 42 percent less than it recorded two weeks ago.

Although studies have shown that Omicron is less severe than previous variants of the virus, such as Delta, the WHO warned on January 12 that it still was “a dangerous virus”, particularly for those who are unvaccinated.

Newsweek reported Tuesday that the Omicron COVID-19 sub-variant BA.2 or “stealth” Omicron had been detected in more than half of U.S. states as it continues to spread across dozens of countries.

The BA.2 variant is feared to be more transmissible than the original Omicron variant, or BA.1, which is now the dominant strain globally and in the U.S.

As of February 1, BA.2 had been found in just over 200 U.S. COVID-19 cases from at least 30 U.S. states, according to Outbreak.info, a coronavirus variant tracking tool. Of course, these figures may change quickly.

BA.2 had also been found in about 57 countries.

On January 28, Trevor Bedford, a biostatistics professor at the Fred Hutch disease research center, tweeted that BA.2 had “become predominant in Denmark and India” and was spreading elsewhere.
