Over 20 U.S. states identify Omicron variant cases

At least 22 U.S. states have identified Omicron variant cases, including some that indicate community transmission, according to a new report released by the U.S. Centers for Disease Control and Prevention (CDC) on Friday.

Among 43 cases with initial follow-up, one hospitalization and no deaths were reported, according to the CDC.

The most commonly reported symptoms were cough, fatigue, and congestion or runny nose.

Case investigations have identified exposures associated with international and domestic travel, large public events, and household transmission.

Implementation of concurrent prevention strategies, including vaccination, masking, increasing ventilation, testing, quarantine, and isolation, are recommended to slow transmission of SARS-CoV-2, including variants such as Omicron, and to protect against severe illness and death from COVID-19, said the CDC.

The first U.S. infection case of Omicron variant was identified on Dec. 1.
