Healthy Davis Together reports two more Omicron cases

Testing by Healthy Davis Together has detected two more cases of the Omicron variant in Yolo County.

The variant was identified in two positive samples collected during the week of Dec. 5-11, according to HDT data, bringing to three the total number of Omicron cases identified locally.

Another 71 positive samples collected that week and sequenced by the UC Davis Genome Center were caused by the Delta variant.

The 73 total positive tests collected by Healthy Davis Together in Yolo County marked a decline from the 114 the week before, but total asymptomatic tests performed at the genome center also declined from 44,699 tests the week of Nov. 28 to Dec. 4 to 32,515 tests the week of Dec. 5-11.

A total of 39 Omicron cases had been identified in California as of Monday, according to the state Department of Public Health.

The variant is on its way to becoming dominant in parts of Europe as it has in South Africa, though questions remain about the severity of illness it may cause as well as how well vaccines will protect against it.


Yolo County’s COVID-19 case rate increased over the last week from 8.4 cases per day per 100,000 residents a week ago to 13 as of Tuesday.

The case rate among vaccinated residents is 5.9 and among unvaccinated residents is 25, according to county data. Two people were hospitalized with COVID-19 in Yolo County on Tuesday, both of them vaccinated.

Since Thanksgiving, the city of Davis has seen 89 new cases of COVID-19; Woodland has reported 100; West Sacramento has experienced 175; Winters 35; and the unincorporated areas have seen 86.
