HONOLULU (KHON2) — The Hawaii State Department of Health (DOH) on Friday announced it has detected 12 omicron variant cases on Oahu — the youngest case was reported in a four-year-old.

“Most of the infected individuals have no known connection with one another. This indicates the omicron variant is spreading deeper into our communities,” State Epidemiologist Dr. Sarah Kemble said in a statement.

Dr. Kemble advises close contacts with symptoms to get tested even if they’ve been vaccinated.

The DOH is also investigating four separate coronavirus cases among those who visited the Scarlet Honolulu nightclub on Dec. 3. Samples from two patients showed a molecular clue indicating the possible presence of the omicron variant. Anyone who visited the nightclub on this day is advised to get tested.

Scarlet Honolulu is partnering with Project Vision Hawaii to host a COVID-19 booster clinic on Saturday, Dec. 11, between 7:30 p.m. and 9:30 p.m.

Additionally, DOH officials are investigating a separate COVID cluster report with multiple confirmed cases — including one confirmed omicron case — in relation to a Thanksgiving gathering. In total, there are 16 other close contacts linked to this cluster.
