Get the latest COVID-19 news from infectious diseases expert Mark Rupp, MD, including COVID-19 case rates, types of variants circulating and vaccine updates.

There are currently more than 33,949 cases reported in the United States per day, with test positivity of 8.3%. When test positivity is above 5%, transmission is considered uncontrolled. There are more than 538 deaths per day, an increase of 41% over the past two weeks, and hospitalizations have declined by 9% over the last two weeks.

Since many are using home tests that are not reported through public health or are not testing at all, the official case counts underestimate the actual prevalence of COVID-19.

What COVID-19 variant are we on?

Currently, the dominant variant nationwide is XBB.1.5, with 89.6% of cases, followed by BQ.1.1, with 6.7% of cases. "The original omicron variant is gone now," says Dr. Rupp. "Currently subvariants of omicron are circulating, including XBB.1.5, BQ.1.1 and BQ.1."

XBB.1.5, BQ.1 and BA.5 variants dominating in Nebraska

As of March 4, 2023, XBB.1.5, also called kraken, is the dominant variant in Nebraska, making up 67% of cases. BA.5 is second, with 33% of Nebraska cases.

Which COVID-19 variant do I have? And do COVID-19 tests tell you the variant?

When you receive a COVID-19 test, you won't find out which variant caused your infection. That's because COVID-19 tests only detect the presence of the virus – they don't determine the variant.

Genomic sequencing looks at the genetic code of the virus to determine which variant caused the infection.

Nebraska DHHS sequences test samples after a positive test is identified and reports the total percentage of each variant every two weeks. See the latest genomic surveillance report for Nebraska. Sequencing results are used by public health experts to understand variant trends in the community.

Will COVID-19 variants affect the vaccine?

The best way to prevent new variants is to slow the spread of the virus. The great news is that these proven public health strategies continue to work against new variants as well.

  • Get vaccinated 
  • Choose outdoor activities over indoor activities whenever possible
  • Wash your hands often
  • Avoid close contact with others
  • Wear a mask in public places
  • Stay home if you're sick or have symptoms of COVID-19

"We have a lot of disease out there. People should continue to be careful," Dr. Rupp says. "Get the bivalent booster, try to avoid high-risk settings. If you can't, then I think you should wear a mask."

Get your COVID bivalent booster

Everyone 6 months and older should get an updated COVID-19 booster. These updated bivalent boosters offer protection against the omicron variants, plus the original COVID-19 strain.

In Nebraska, vaccination and booster dose rates need to increase. Evidence shows those vaccinated and boosted continue to be protected against severe disease, hospitalization, and death – even with the latest variants. Unfortunately, Nebraska is behind compared to other states, with only about 16% of those who are eligible to have received a booster actually getting the shot as of January 2023.
