Here we go again. Just when you thought you could go back to normal, a new, highly-mutated coronavirus variant has emerged in the U.S. Scientists aren’t sure if the omicron variant is more severe or milder, but early evidence suggests it’s more adept at evading the immune systems than other strains. Omicron is the most transmissible variant of coronavirus yet, according to several warning signs. Many people are now wondering if it’s time for us to change our safety habits. You don’t have a 2020 hibernation. Experts agree that we are in a different place than last winter. There are now many COVID-19 boosters and vaccines. The current vaccines provide protection against severe diseases with omicron, which is a good thing. However, Dr. Abraar Karan at Stanford University, an infectious disease physician, says that there is good hope that the current vaccines offer protection against severe disease with omicron.
Don’t panic but be aware of the risks you are willing to take. We asked several infectious disease experts for their advice on how to live in the age of omicron. Keep in mind that things are constantly changing so be alert. As we learn more, public health advice could change. Do I need to mask indoors again, even if it is not necessary? If you aren’t vaccinated, please don’t mask indoors. Experts agree. If you’re at greater risk of serious disease due to your age, underlying health conditions, or if it is a common occurrence in your community, you should wear masks. We know vaccines don’t always protect the elderly and immunocompromised. “The things we’ve gotten tired doing, we need keep doing them, especially indoors,” says Dr. Tom Frieden (ex-director of the Centers for Disease Control and Prevention). Dr. Monica Gandhi, an infectious diseases specialist at the University of California San Francisco, said that this advice would still be valid if there were no omicron variant. “Because we still have [delta] case circulating in the country.” Although you don’t need to wear a mask outside, it is a good idea if you are in a group and don’t know the vaccination status of others, Dr. Julie Vaishampayan (chair of the public health committee of Infectious Disease Society of America) said during a Thursday media briefing.
Do I need to upgrade my N95, KN95, or another highly protective mask? Three-ply cloth or surgical masks can prevent the spread of infectious particles, if they fit well and provide some protection. However, experts recommend that an N95 or KN95 respirator be used in public areas. This is especially important if you are at high risk. Frieden says that if you’re older, or have a weaker immune system, you should consider using an N95 mask. Karan, a Stanford University professor, suggests that people with other conditions that could put them at greater risk such as obesity, diabetes, or poorly controlled diabetes should upgrade to a high-quality N95/KN95 mask. Karan suggests that you also upgrade your mask if you live with someone who is at high risk. Gandhi notes that double masking with a surgical mask and a cloth mask will increase your protection.
Should I cancel my holiday travel plans Dr. Henry Wu, Emory TravelWell Center director and associate professor of infectious disease at Emory University School of Medicine, advises that you not cancel your holiday travel plans too soon. Anyone who is considering traveling should take the time to consider both your own risk and certain practical considerations about their destination. The U.S. now requires that all travelers to the U.S., even those returning home, be tested for the coronavirus at least one day before they depart. You will need to know where to find a test that qualifies if you are in another country. This could prove to be a logistical nightmare. Keep in mind that the situation on ground is constantly changing so make sure to keep an eye on the CDC’s travel warnings. You should avoid countries that are experiencing a surge or have overcrowded health systems. Wu states that you don’t want your health to be compromised by overcrowded hospitals. Although domestic travelers are not required to test before they fly, it is a good idea to do so both before and after you arrive. This is especially true if you are visiting someone with high-risk conditions. Wu will do the same when he visits his parents in Hawaii next week. He says, “I will, even if it’s not necessary, test myself before I go, and I think I’ll take some self-test kits home when I get back, just to make sure I’m not infected at that time.” Wu states that if you aren’t vaccinated, 65 or older, or have any medical conditions that could make you more susceptible to severe COVID-19-related diseases, it is a good idea to reconsider whether now is a good time for you to travel. Wear a tight-fitting, high-quality mask if you fly or take public transport to your destination. Should I bother to get a booster, given all the concerns about omicron evading our vaccines? This week, the Biden administration urged people to get a booster to protect against omicron. This recommendation is consistent with recent science that boosters increase your antibody levels. A preprint study showed that a third dose mRNA vaccines could produce a stronger immune response, according to Dr. Kavita Patel. She is a Brookings Institution nonresident fellow and primary care physician. This could provide greater coverage against a variant such as omicron, she said. “This is why I think you are hearing many of us, many doctors and public health people, scientists saying boosters really do matter.” Paul Bieniasz, a Rockefeller University virologist who studies how the immune response broadens over time. He agrees. He says, “I’m someone who’s been vaccinated 3 times and I think that’s absolutely right.” Gandhi states, “I believe anyone who is around immunocompromised people should absolutely be ensured they boost.” “I protested global vaccine equity and was not going to get a booster. I received one because my father, an immunocompromised man, needs it.
Is it safe for large indoor gatherings such as holiday parties? Do guests need to test their own health before they arrive? Safety is important. But so is gathering with loved one at this time of the year. There are steps you can take that will lower the risk for everyone. Vaishampayan says, “What we need is to add more layers of protection.” Karan says that everyone should have gotten a COVID-19 vaccination and booster shot, if they are eligible. If you have rapid antigen testing, make sure your guests have one. This is especially important for those who are traveling from other parts. “It’s a great way of preventing someone who is infected from getting in and infecting another person,” Dr. Carlos Del Rio, an infectious diseases specialist at Emory University, said to reporters this week. Karan points out that “testing is really just a snapshot in the past,” so ensure guests test the day before the actual gathering. This is because if the virus is still incubating and a person was just exposed, they can test negative one day and positive another. However, rapid antigen tests can be expensive. The most expensive one will run you about $12 per test, if you can find one. This week, the Biden administration announced plans to address this issue. People with private insurance will be able to get reimbursements for at-home tests and health clinics will offer free testing to the uninsured. Gandhi suggests that you prioritize testing anyone who has not been vaccinated, or is vaccinated, but is showing symptoms. Vaishampayan suggests that the party be moved outdoors if the weather permits. You can improve ventilation indoors by opening windows, as the temperature allows, at minimum. Gandhi suggests that guests with immunocompromised should avoid areas that are not well ventilated and to wear masks if they are eating or drinking. Or consider skipping large gatherings, says Karan. Karan says, “If you have a high risk person at home, this may not be the time to host large gatherings because vaccines here don’t completely stop transmission. They just reduce the likelihood it could happen.” Should I avoid dining indoors in restaurants? Wu says there is no clear answer for every situation. He says, “I just evaluate each situation individually.” Consider transmission levels in your area, ventilation and, most importantly, your risk level. Wu said that he assesses the restaurant’s crowdedness and ventilation before deciding whether it is safe to go. Karan suggests that indoor dining should be avoided if you want to be safe. Scientists are still learning more about microns. He recommends that indoor dining be avoided until you have more information about omicron. His best advice? “Be conservative right now.”
