First Omicron variant of COVID-19 reported in Missouri

ST. LOUIS, Mo. (KBSI) – Missouri has its first case of the Omicron COVID-19 variant. The Missouri Department of Health & Senior Services (DHSS) announced the state’s first case on Friday, Dec. 3.

The person with the Omicron variant lives in St. Louis City and has a recent domestic travel history.

The sample was originally sequenced as part of commercial laboratory surveillance and results are currently awaiting confirmation by the CDC.

The World Health Organization classified this variant, B.1.1.529, now known as Omicron, as a Variant of Concern due to identified concerning types of mutations.

The transmissibility and disease severity caused by Omicron are still unknown. Public health experts and scientists are also studying the degree to which existing vaccines and therapies protect against Omicron and how this variant may impact the health and safety of citizens.

The Delta variant represents more than 99 percent of COVID-19 cases, according to Donald Kauerauf, DHSS Director.

Citizens are urged to complete their vaccination series for COVID-19 and get their booster. To learn more about Missouri’s variant monitoring efforts, visit Health.Mo.Gov.
