With a new COVID variant on the rise, which US states have the most cases?

Some states are being hit harder than others this summer as a new COVID-19 strain (XGF) continues to spread.

Some regions of the U.S. are still experiencing higher rates of positive COVID tests than others, though reporting has slowed down enough nationwide that the Centers for Disease Control (CDC) has begun allowing more time to pass between certain types of updates, such as those on variant prevalence.

Testing, cases, hospitalizations and deaths are still being recorded on a weekly basis, however, even amid the chaos of ever-changing strains, recommendations and cuts to vaccine development funding.

Here's what to know about the latest data.

How many COVID cases were reported nationwide?

During the week ending on Aug. 2, 8.5% of the 25,731 Americans tested were positive for COVID, according to the CDC's latest data. This was 2% increase from the week prior.

During the same period, only 0.3% of cases resulted in death and 0.9% resulted in an emergency room visit, a 0.1% decrease from the week prior for both categories.

Western and southern states, including Washington, Oregon, Idaho, California, Nevada, Arizona, New Mexico, Texas, Oklahoma, Arkansas and Louisiana, had higher percentages of positive COVID tests during the week ending Aug. 2.

What is the most common COVID variant?

The CDC has moved to using longer data timeframes for COVID tracking due to low reporting from states. According to the latest data for the two weeks ending June 21, variant NB.1.8.1 remained the most common, accounting for 43% of cases, followed by LP.8.1 at 31% of cases and XFG at 14%.

NB.1.8.1 experienced a meteoric rise to becoming the predominant variant, accounting for 0% of cases in April and only 10% in the last week of May, up to 24% at the beginning of June and 43% by the end.

XFG, a combination of variants F.7 and LP.8.1.2, is on the rise as of late, having been responsible for 0% of U.S. cases through March, 11% by early June and 14% by late June.
