WHY MORE PEOPLE THAN EVER ARE TESTING YOLO COUNTY SCHOOL POSITIVE FOR COVID-19 — AND SHOULDN’T CHILDREN VACCINATION RATE LAGGING BEHIND BE ASHAMED UC Davis infectious disease expert explains why the omicron variant is so contagious and how it is expected to spread in Davis and around the U.S. BY MAYA SHYDLOWSKI featuresh@theaggie.org Students shouldn’t be ashamed if they test positive for COVID-19 in the coming month, according to UC Davis infectious disease expert Dr. Dean Blumberg. COVID-19 cases are urging across the U.S., including in YOLO county, fuelled by the highly contagious omicron variant. Blumberg said that the rate of COVID-19 infection of the coronavirus is the highest it has ever been in the country, and it is projected to keep rising until its estimated peak in early February, so if you test positive, know that you are definitely not alone. “A lot of the time when people do test positive, and they have to tell the people who they’ve had contact with, they’re embarrassed about it,” Blumberg said. “They feel bad that they might have exposed other people. This is such an incredibly infectious and transmissible strain that when people do test positive and they let other people know, they’re really being heroes. They are being brave. They shouldn’t be ashamed.” Even some students who have social distanced, masked and taken the safety precautions recommended by the Centers for Disease Control and Prevention, like fourth-year managerial economics major John Giovannoni, are testing positive during this recent surge. When Giovannoni returned to Davis after winter break and got his routine COVID-19 test to allow him back on campus, he unexpectedly tested positive. “I have always been extremely cautious with COVID, was vaccinated twice as soon as possible and got the Moderna booster in November,” Giovannoni said. “Over the holiday break, I continued to stay inside when I was home to make sure that none of my family would get infected, so we didn’t have to ruin Christmas.” Despite many people’s best efforts to be safe, stories like Giovannoni’s are not uncommon. Although a lot is still unknown about the rapidly spreading omicron variant, Dr. Blumberg shared why scientists believe that it is causing such a steep surge. He said that the strain is far more transmissible than previous variants, in part because it has 50 more mutations than the original strain, which allow it to bypass developed antibodies from vaccination or previous infection. He also said that the omicron variant is believed to be two to five times more transmissible than the Delta variant. Blumberg compared the recent rate of infection to those of last

winter, during another national COVID-19 surge. “For the surge that we saw last winter, in December and January, the model suggested that there were about 80,000 infections per day in California,” Blumberg said. “What we’re seeing now is over 120,000 cases a day, and it’s going to get even worse, because the model suggests that it’s going to peak at over 300,000 [cases] a day in early February. That’s about four times higher than the largest surge that we had last year.” Despite these large statistics, Blumberg said that one silver lining in this surge is that the omicron variant causes a generally milder disease than previous variants. “What’s been found in the laboratory is that the omicron variant results in about 70 times higher concentrations of virus in upper respiratory airway cells, but about 10 times lower concentrations in lung tissues,” Blumberg said. “That suggests that the reason that it’s more transmissible is the higher concentrations that’s favorable for spread in the upper respiratory tract, but then it doesn’t go to the lower respiratory tract.” Because the omicron variant seems to inhabit the lung tissue less, it is less likely to cause severe respiratory illnesses like pneumonia. Blumberg mentioned that a study in the U.K. showed that this variant has resulted in fewer cases that end up in the emergency room or require hospitalization at all, which could be indicative of a lower percentage of people who get sick in the U.S. needing hospitalization — though he mentioned that it is impossible to predict for certain how U.S. hospitals will be affected in the coming weeks. Davis has seen this sharp rise in cases over the past month, during which the positivity rate of Healthy Davis Together testing sites has been around 10% — the highest that it has been thus far throughout the pandemic. UC Davis’s asymptomatic testing during week one of winter quarter also detected its highest positivity rate to date, at over 4%, prompting the campus to extend online instruction until Jan. 28. Giovannoni said that after Jan. 28, he hopes that accommodations will be made, both for students who want to be on campus, and those who do not feel safe or comfortable to do so yet. “Moving forward, I hope there is some sort of hybrid option for those that want to go to class and ones that are sick or don’t feel comfortable,” Giovannoni said. “Since I’ve been highly cautious compared to most and I still caught COVID, I don’t think it’s going to go away all that soon, but I’m glad it appears to be mild from my experience and stories from others.”

STATE AVERAGE

Schools are promoting vaccination with incentives BY RACHEL SHEY city@theaggie.org

Vaccine Clinic at the ARC at UC Davis. (Quinn Spooner / Aggie) As of Jan. 7, 34.1% of Yolo County children ages 5-11 have received at least one COVID-19 vaccine, which is ahead of the state average of 27.4%. Only 61% of Yolo County children ages 12-17 have received at least one COVID-19 vaccine, which lags behind the state average of 72.7%. This discrepancy may simply be a result of the different dates at which Yolo County updates its information, according to Yolo County Public Information Officer John Fout. “I don’t actually know if the numbers are lagging,” Fout said. “It just might be the way that our numbers are reported. It depends on when you get the stats and compare them to the state statistics. Our data lags a bit more than the state’s.” In the wake of UC Davis’ decision to hold remote instruction through Jan. 28, elementary and high schools in Yolo County may consider returning to online classes as well. As of now, the schools are planning to resume in-person classes and are awaiting further instruction from the public health officer, according to Yolo County Office of Education Public Information Officer Anthony Volkar. “We are aware and we’ve seen the increase in cases due to omicron, but right now, all schools in Yolo County are scheduled to resume,” Volkar said. “Davis resumed classes on Monday Jan. 3, Esparto opened on Tuesday, two of our districts opened on Wednesday and Woodland starts classes next Monday. We are seeing increased cases, but right now, there is no anticipation that school will close.” Volkar said that schools are not mandating COVID-19 testing or vaccination. Schools will mandate vaccination when the COVID-19 vaccine is approved by the FDA, at which point it will become one of the mandatory vaccines that students must receive to go to school. Yolo County distributed testing kits to promote testing but does not require a negative COVID-19 test for students to return to school. “All of our districts are offering testing to our students weekly, and most of it is on site,” Volkar said. “We released 30,000 rapid test kits, so every student in Davis is able to get a rapid test kit. If they are positive, they are asked to report to their school and not attend class. But this is voluntary and no one is required to do this.” Schools are also promoting vaccination with clinics, according to Volkar. Vaccines have been available to the youngest elementary school children since early November, and Yolo County has accomplished a fairly high rate of vaccination among these youngest children. “Every school has hosted a vaccine clinic; we also hosted a youth vaccine town hall with Dr. [Aimee] Sisson that was very popular,” Volkar said. “River Cats had a promotion where they were giving away tickets. We’re generally very proud of the vaccination rate for children 5-11 because those are very strong compared to the state numbers, but we could generally do a lot more work for the group ages 12-17 because those are below the state average.” YOUTHVAX on 7

COVID-19 ORAL ANTIVIRAL TREATMENT RELEASED IN LIMITED SUPPLY TO YOLO COUNTY PHARMACIES Paxlovid and Molnupiravir reduce risk of hospitalization or death from COVID-19 infection BY LEVI GOLDSTEIN city@theaggie.org The U.S. Food and Drug Administration (FDA) recently issued Emergency Use Authorization for oral COVID-19 treatments Paxlovid on Dec. 22 and Molnupiravir on Dec. 23. These antiviral pills are now available at select pharmacies in Yolo County, according to a Yolo County press release published on

Dec. 28. “With the Omicron variant causing a rapid spread of COVID-19 cases in Yolo County, these new antiviral pills come at a critical time,” said Yolo County Health Officer Dr. Aimee Sisson in a statement from the press release. Paxlovid reduces risk for hospitalization or death from the COVID-19 virus by approximately 89%, according to Pfizer, its manufacturer. A study sponsored by Merck Sharp & Dohme Corp., Molnupiravir’s manufacturer, found that Molnupiravir

reduces risk for hospitalization or death by approximately 31%, according to the New England Journal of Medicine. The FDA also confirmed the effectiveness of both Paxlovid and Molnupiravir in two separate press releases. Molnupiravir and Paxlovid should only be taken with a prescription. They are intended to be taken within five days of symptom onset and while symptoms are still mild. Molnupiravir is only approved for adults while Paxlovid is available to adults and children 12 years of age or older. Yolo County received 140 prescriptions of Molnupiravir and 20 prescriptions of Paxlovid, according to the Dec. 28 press release. The Rite Aid pharmacy on West Main Street in Woodland has both medications, while Winters Healthcare has only Molnupiravir. Winters Healthcare currently fills all prescriptions at the CVS pharmacy on North 1st Street in Dixon. Since the medication supply is limited, distribution to those at high risk of severe disease will be the top priority. “They go to people who are at severe risk of hospitalization or death from COVID, generally people who have comorbidities, for example, anyone who is immunocompromised,” said John Fout, the Yolo County Public Information Officer. Additional shipments of the drugs are expected to be delivered to more pharmacies in the coming months. However, they will not likely be available for mass distribution any time soon, according to Fout. “There’s going to be a large amount of people who are getting sick, and there’s just going to be no way that all these people can be treated, unfortunately,” Fout said. Oral antiviral treatment should not be a substitute for vaccination or wearing masks to prevent the spread of COVID-19, according to Dr. Sisson. “Please continue to take steps to avoid infection in the first place and don’t count on an antiviral pill being available if you get infected in the next few weeks,” Dr. Sisson said in the Dec. 28 press release.
