What omicron subvariant is causing the most COVID cases in the U.S. now?
Posted On July 6, 2022
There’s yet another version of COVID-19 now dominating cases in Utah and the United States.
The omicron subvariant known as BA.5 now accounts for almost 54% of the county’s COVID-19 cases, according to the latest estimates by the Centers for Disease Control and Prevention through the week ending July 2. For the region that includes Utah, BA.5 makes up just over 50% of cases.
BA.5, along with another subvariant known as BA.4 that does not appear to be spreading as rapidly, can evade some of the antibodies produced by COVID-19 vaccinations and infections, including from earlier versions of omicron, according to The New York Times.
In Utah, coronavirus cases continue to climb along with hospitalizations. As of June 30, the most recent data reported by the Utah Department of Health and Human Services, the seven-day average case count was 1,058, more than a 9% increase from the previous week, while hospitalizations jumped nearly 16%.
Four counties in Utah — Salt Lake, Summit, Tooele and San Juan — are at high community levels of COVID-19, where universal masking is recommended by the federal government, according to the CDC’s calculations of case counts as well as hospital admissions and capacity by county.
Just over 45% of the nation’s counties are currently at low community levels for the virus, and more than 35%, at medium levels, where those considered at higher risk for severe illness are advised to wear masks and take other precautions. Less than 20% are at high levels.
When it comes to the CDC’s measurement of transmission levels of the virus. However, more than 85% of the country, including most of Utah, is at a high level. The CDC uses a lower threshold of case counts along with the percent of positive tests to determine transmission levels.
Public testing for the virus has dropped off nationwide, with many people no longer checking to see if they have the virus or relying on results from home test kits that are not required to be reported, The New York Times noted, suggesting that’s created ”a foggier look at the state of virus across the country.”
In Utah, most COVID-19 testing was turned over to private providers by the end of March, as part of Gov. Spencer Cox’s “steady state” plan to treat the virus like the flu or other endemic diseases. The state health department, now merged with human services, also began updating Utah’s COVID-19 numbers weekly rather than daily.
