Healthy Davis Together issued the following news release today (Dec. 22):
The 新澳门六合彩内幕信息 Davis Genome Center has detected and confirmed an additional 42 cases of the B.1.1.529 (omicron) variant of SARS-CoV-2, the virus that causes COVID-19, in Yolo County, specifically in Davis, El Macero, West Sacramento and Woodland.
GET TESTED FOR COVID-19
Testing locations and hours in Davis, Woodland and throughout Yolo County are available on the . Appointments are preferred, but walk-ins are accepted at most testing locations. Parking is free.
The Genome Center had previously detected only two omicron cases, both in West Sacramento. The variant has also been detected in trace amounts in the city of Davis鈥 sewage through Healthy Davis Together鈥檚 wastewater monitoring initiative.
Omicron has been identified as a by the U.S. Centers for Disease Control and Prevention, or CDC, and the World Health Organization, or WHO. The CDC is working with other U.S. and global public health and industry partners to learn more about the variant, including how severe its cases are compared to other variants and the amount of protection provided by existing vaccines.
The Genome Center screens every positive COVID-19 test conducted by Healthy Davis Together for all currently known SARS-CoV-2 variants of concern so that action can be taken to alert and protect the community. Tests administered from Dec. 12 to 18 yielded the 42 new cases.
Several of the Davis cases have been linked to a single workplace holiday party. The party, with approximately 50 attendees, and subsequent workplace spread are associated with an outbreak of at least 16 cases, of which 10 are known so far to be omicron. Of the 16 people infected, all were fully vaccinated and eight had received their booster shots. At this time, all known omicron cases are in isolation or have completed isolation.
鈥楾ake additional precautions鈥
鈥淭he omicron variant is spreading quickly in Yolo County and accounted for 41% of new cases detected by the 新澳门六合彩内幕信息 Davis Genome Center last week,鈥 said Aimee Sisson, Yolo County public health officer.
鈥淭he spread of omicron is coming at a time when many people are traveling and gathering for the holidays,鈥 she said. 鈥淓veryone, including fully vaccinated persons, should take additional precautions right now. Wear a mask that fits and filters well when you are indoors, improve indoor ventilation with portable air filters and ask everyone attending a gathering to test right before the event. In addition, anyone who isn鈥檛 vaccinated or boosted should get vaccinated as soon as possible in order to protect themselves against severe COVID-19 illness.鈥
Wastewater monitoring
The detection of the omicron variant through clinical testing comes as genetic markers of the variant have been identified in the city鈥檚 wastewater by Healthy Davis Together and its partner, the Sewer Coronavirus Alert Network, or SCAN. The Davis sewage treatment plant is one of eight that SCAN monitors by testing daily samples of solids in wastewater, which carry signs of the virus and its variants if present in a community. Wastewater monitoring is another tool that can be used as an early detection system for new strains and future spikes of COVID-19.
鈥淭he information collected through Davis鈥 wastewater monitoring program can be useful in our long-term community effort to reduce the spread of COVID-19,鈥 said Brad Pollock, director of Healthy Davis Together and chair of the 新澳门六合彩内幕信息 Davis Department of Public Health Sciences.
How to stay safe
Here are the most important things people can do right now to prevent the spread of COVID-19, including the omicron variant:
- Get vaccinated. With the recent approval of the Pfizer vaccine for children 5-11 years of age, HDT strongly encourages everyone 5 years and older to get vaccinated.
- If you鈥檙e already vaccinated, get boosted two months after a Johnson & Johnson vaccine or six months after the second Moderna or Pfizer vaccine.
- Get tested if you have symptoms or have been exposed to someone infected with COVID-19.
- If you are planning to travel or gather, it鈥檚 recommended that you get tested one to three days prior to and three to five days after traveling or gathering, even if you鈥檙e vaccinated.
- If you aren鈥檛 vaccinated yet, it鈥檚 important to get tested regularly.
- Follow local mask guidance. N95s, KN95s and KF94s provide additional protection and are good options for people more vulnerable to severe disease, for example, older adults and people with underlying conditions.
