Omicron surging rapidly in Seattle area, projections show huge spike within a week

The Omicron COVID-19 variant is surging in the Seattle space with pace that has the potential to overwhelm well being care methods, scientists and well being officers stated Friday at a media briefing.

Within one week the variety of Omicron circumstances in King County is projected to soar to about thrice the height of the Delta wave in August, to greater than 2,000 circumstances every day. Instances of COVID-19 in the county are up 50% since Thanksgiving.

“The Omicron outbreak we’ve been speaking about is now not theoretical, it’s actual.” stated King County well being officer Jeffrey Duchin. “It’s right here and it’s shifting quick.”

About 37% of COVID-positive samples collected on Dec. 13 have been constructive for Omicron, according to data from the College of Washington’s virology lab, which analyzes a massive proportion of Washington state’s assessments. That’s virtually double the quantity from Dec. 10. The info was collected utilizing a fast technique that’s not as foolproof as gold-standard genomic sequencing, however nonetheless has excessive accuracy. 

“We don’t know precisely what case counts shall be in January in King County and in the U.S., however I’m sure it is going to be the very best case counts we’ve seen all through the pandemic,” stated Fred Hutchinson Most cancers Analysis Heart scientist Trevor Bedford.

The fast-spreading variant is doubling about each 2.2 days in King County, much like charges seen in different areas, according to Bedford. At that fee, there shall be roughly 2,100 every day circumstances, and rising, of Omicron in the county on Dec. 22.

“Companies and healthcare services ought to plan for the affect on their workforce,” stated Duchin. He doesn’t anticipate instantly altering any main public well being necessities in the county. “However I believe individuals ought to plan for big scale absenteeism. It’s finest to be ready than be taken abruptly,” he stated.

The primary case of Omicron seemingly arose in South Africa round Oct. 1 stated, Bedford. The variant is now soaring in Europe, and the U.S. Facilities for Illness Management says it could peak in the U.S. as quickly as January.

Few areas have as thorough surveillance for variants as Washington. Bedford anticipates that unfold in different cities, after which to rural areas, can even be fast. “It appears to be like like Seattle and King County are going to be a bit forward of the curve in the US,” stated Bedford.

Duchin advises individuals who haven’t but been vaccinated to get their photographs, and those that haven’t acquired a booster to get one. The variant causes infections in a excessive proportion of vaccinated people, however he anticipates that vaccination will protect towards extreme illness. Boosters will present further safety.

Duchin additionally advises doubling down on different measures. These embody ventilating rooms, limiting gatherings, getting examined and staying residence when sick, and sporting a prime quality masks, comparable to an N95.

“Keep away from crowded indoor areas throughout the vacation season. Restrict the variety of gatherings and when doable do a fast check the day of the gathering.” He additionally stated bigger, well-ventilated areas, with open home windows, are safer. “Keep in mind that half or extra of infections are unfold from individuals earlier than they’ve signs. Speedy testing earlier than gathering may also help determine individuals with COVID-19 early.”

Whereas early findings from South Africa supplied hope that the variant would possibly trigger much less extreme sickness than Delta, emerging data from Europe suggests illness severity could also be much like Delta’s.

“It’s vital to acknowledge that we don’t but have a clear image of the severity of sickness Omicron causes in comparison with Delta,” stated Santiago Neme, medical director of UW Medical Heart Northwest.

Comparatively excessive charges of vaccination in King County will assist blunt the results of Omicron. 86% of individuals 16 and over have accomplished their photographs. About two-thirds of people 65 have been boosted, although lower than half of individuals beneath 50.

However there’s nonetheless a substantial unvaccinated inhabitants. 160,000 adults in King County haven’t acquired a shot in any respect, and 250,000 haven’t but accomplished their collection. “Omicron goes to search out many of those individuals,” stated Duchin.

And even when the variant seems to trigger milder sickness, the sheer variety of people who find themselves projected to grow to be contaminated in a quick time period might trigger a surge at healthcare services.

Hospitals have been working at full or overflow capability for months in many areas of the state, stated Neme. “This has to do with staffing shortages, but in addition a rise of transfers from different areas of the state of Washington and neighboring state hospitals which can be coping with a lot increased charges, partly attributable to decrease vaccination,” and fewer stringent masking, he stated.

In a media briefing on Monday, Taya Briley, vice chairman and common counsel for the Washington State Hospital Affiliation, stated state hospitals are already “bursting on the seams,” based on a report from KUOW. Many sufferers are caught in hospital beds due to roadblocks transferring them to expert nursing houses or assisted dwelling services, she stated.

Many employers are in a holding sample as Omicron emerges, and Seattle-area tech firms have a variety of plans in place. Docusign, AppleLyftFordUberGoogle, and others over the previous week have pushed again many previously-announced plans. Some firms comparable to Microsoft had already given up on predicting a timeframe for full reopening of workplaces.

Duchin advises workplaces to take all of the precautions they will. “Faculties may see impacts from circumstances in workers and college students after the winter break,” he added.

Boosters are in excessive demand now, however King County has been rising its provide of vaccine. The ten county-operated websites have bumped up vaccination capability by 60% in the previous month.

One early dataset from the UK means that two doses of the Pfizer/BioNTech vaccine have been roughly 35% efficient at stopping symptomatic an infection with Omicron however boosting with a third dose bumped that as much as 75% effectiveness. Analysis on effectiveness of vaccines, severity of an infection and different questions is ongoing.

Duchin additionally advises individuals who have had previous COVID-19 an infection to get their shot, as they’re at risk.

Verification of Omicron-positive samples by sequencing sometimes takes 5 to seven days, stated Alex Greninger, head of the UW virology lab. Virtually all the Omicron-positive samples topic to verification to date have been constructive for the variant, and the early estimates of excessive Omicron prevalence will maintain, he stated.

The rise in Omicron detected by the UW tracks closely with numbers in Connecticut, which is conducting comparable surveillance. New York is experiencing a rapid COVID-19 surge and a spike in Omicron.

“Omicron is throwing a new problem at us on the most inconvenient time,” stated Duchin.
