As the number of asymptomatic as well as symptomatic people who test positive for COVID-19 varies by week in Yolo County and mask wearing guidelines continue, it’s important to remain vigilant and continue to get tested if you are not vaccinated, if you have symptoms or have been exposed to someone with COVID-19, and before and after traveling or gathering – even if you are fully vaccinated.
NOTE: From January 2 – 29, 2022, only a sample of positive COVID-19 tests could be genotyped because of the large number of positives. The prevalence of each variant was calculated and the estimated value for each variant is reported. The actual number of samples genotyped is presented with the parenthesis next to the reported number.
As part of Healthy Davis Together’s free COVID-19 testing operations, all positive COVID-19 samples from Yolo County are routinely screened by the UC Davis Genome Center for variants, including Delta, Omicron and other variants of concern and variants of interest. The new positive COVID-19 cases in Yolo County are nearly all BA.2, one of the more contagious variants of concern that is now the prevalent type though much of the country.
That’s why testing, especially for people who are not yet vaccinated or who have symptoms or have been exposed remains so important. For information on where to get a free COVID-19 test visit our testing page on this site.
