Applying that to real life is an entirely different thing," he said. CNN: Can you give us a quick refresher what protective measures are effective against this very contagious BA.2 variant? SARS-CoV-2 B.1.1.529 (Omicron) variantUnited States, December 1-8, 2021. There are several ways this can happen: Droplets or aerosols. This age group is currently not eligible for vaccination and is a population in which some prevention strategies, such as isolation and mask use, might be difficult or impractical to implement. By submitting a comment, you accept that CBC has the right to reproduce and publish that comment in whole or in part, in any manner CBC chooses. Persons who only had signs or symptoms (and no positive SARS-CoV-2 test result) were considered to have a probable case. The subvariant made up 74% of new infections as of April 16, 2022. If you have a question you'd like us to consider for a future post, email us at goatsandsoda@npr.org with the subject line: "Weekly Coronavirus Questions." September 7, 2022.

And should we skip large indoor events again? Not only does it keep your cheeks warm, but who wants to take their gloves off to fuss with a mask in sub-freezing temps? The AR was lower among household contacts of index patients who reported ever wearing a mask at home during their potentially infectious period (39.5%, 88 of 223) compared with household contacts of index patients who reported never wearing a mask at home during this period (68.9%, 124 of 180, p-value<0.01). Ive talked before about how the new guidelines from the US Centers for Disease Control and Prevention can be used here. What exactly does a small group mean? Fifth, this investigation did not definitively distinguish between secondary and potential tertiary cases within a household. So, does this mean youre at risk every time you step outside? The key is really just ensuring that theres adequate distancing, particularly if youre in a situation where someone sneezes or coughs within a few feet of you, Roberts emphasized. While outdoor transmission of COVID-19 in low-risk settings is "generally uncommon," Dr. Adalja says that it's . 1CDC COVID-19 Emergency Response Team; 2Epidemic Intelligence Service, CDC; 3Oak Ridge Institute for Science and Education, Oak Ridge, Tennessee; 4Chicago Department of Public Health; 5Connecticut Department of Public Health; 6Milwaukee Health Department; 7Utah Department of Health; 8CDC Foundation, Atlanta, Georgia. Terms & Conditions. Roberts stressed that COVID spread outdoors is much less common than spread indoors, but nothing is perfect. Why Are There So Many Omicron SubvariantsAnd What Can They Tell Us About the Future of the Pandemic? mmwrq@cdc.gov. Studies conducted prior to omicron show that being outside greatly reduces your risk of infection with the coronavirus. Spreading COVID outside was possible, but not probable, experts advised in 2020, urging cooped-up citizens to turn to Mother Nature as an antidote to the isolation of lockdowns. Since November 2021, Omicron has been the dominant severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant that causes the coronavirus disease 2019 (COVID-19) and has continuously impacted human health. Then came Omicron, with an reproductive rate almost twice as large: 9.5. Research before the emergence of the delta variant indicated that the risk of getting infected with the coronavirus was up to 20 times lower outside compared to inside and the chance of. A majority of index patients were White (59.0%, 108 of 183), and 21.3% (39 of 183) were Hispanic/Latino. Regular sanitization of toys and other items in daycares and schools where children are at play may also be helpful, he said, given how often kids put items directly in their mouths. CDC twenty four seven. Fully vaccinated was defined as completion of the primary vaccination series 2 weeks before the index date and stratified into completion <5 months or 5 months before the index date. Thus, the latest dominant COVID subvariants have a reproductive rate of around 18.6, tying or surpassing measles, the worlds most infectious viral disease, according to Esterman. Given how quickly information about omicron is changing, we decided to reach out to Dr. Kirsten Bibbins-Domingo, a professor at the UCSF School of Medicine, to . Centers for Disease Control and Prevention. They help us to know which pages are the most and least popular and see how visitors move around the site. * Persons self-reported their race (White, Black, Asian, American Indian or Alaska Native, or Native Hawaiian or other Pacific Islander), ethnicity (Hispanic/Latino or non-Hispanic/Latino), and gender (male or female) from lists of options and had the opportunity to state another option if their race, ethnicity, or gender was not listed. "Doing experiments inside a lab where humidity is controlled is one thing. Discovery Company. With previous coronavirus variants, like alpha and delta, being outdoors provided good protection against infection, but with the newest Omicron subvariants, being at an outdoor event could be somewhat risky. Closed Captioning and Described Video is available for many CBC shows offered on CBC Gem. Crowded settings can raise your likelihood of being close to someone with COVID-19. For example, if you work in an office that has pretty good ventilation and is well-spaced, and requires proof of vaccination, you may consider not masking in that setting. Box 500 Station A Toronto, ON Canada, M5W 1E6. S&P Index data is the property of Chicago Mercantile Exchange Inc. and its licensors. Are we back to square one with the pandemic? All variants and subvariants have changes in their genetic code, compared to the original virus they came from. COVID-19 cases have been declining across the country. But if it's a casual interaction outside, even if it's relatively crowded, I'm comfortable not having a mask on. While outdoor events are safer than indoor events, theyre not 100% safe, Majumder told the news outlet. Age at index date was determined from date of birth or self-reported age. A computer modeling study conducted in 2021 found that certain conditionslike wind speed and direction and cool, moist ground temperaturesplay an important role in airborne transmission. Activities like coughing, singing, shouting, or breathing heavily due to exertionincreasethe risk of transmission. Third, COVID-19 prevention measures (vaccination, isolation, and mask use) are likely highly correlated within households, and the identified risk factors might not be independent predictors of transmission. "The mutations of BA.5 impact its spike protein in part and result in some important 'upgrades' in the ability of the virus to infect humans more quickly and also attach to the lungs," Dr. Blaivas said. A new study out of Hong Kong suggests Omicron might be surviving longer on everyday objects than its early predecessor raising questions about which basic precautions to prevent surface-based transmission might still be warranted. Corresponding authors: Julia M. Baker, nwk0@cdc.gov; Jasmine Y. Nakayama, qdt2@cdc.gov. When an . Beta, Delta, and Omicron, to name a few. Thats a personal decision that will differ from person to person. 95% CIs for attack rates are represented by error bars. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Trends in disease severity and health care utilization during the early Omicron variant period compared with previous SARS-CoV-2 high transmission periodsUnited States, December 2020January 2022. "More evidence is needed to account for the increased transmissibility of (Omicron) observed in various community studies," the researchers wrote. So if you find yourself worrying about not being able to distance yourself in a crowded outdoor situation with people of unknown vaccination status, slip a mask on. When do infected people transmit the virus? CDC twenty four seven. "It is more transmissible than other previous variants because it can evade previous immunity from COVID infection and vaccination.". They can also be exposed by inhaling aerosol particles that are spreading away from the infected person. When it comes to COVID, the outdoors are great for two main reasons: there's plenty of fresh air outside, and you have more space to keep a distance, Milton says. Risk is also lower if the mask or respirator is a type that offers greater protection. Did you encounter any technical issues? Experts say staying outdoors for dinners during the holiday may help reduce transmissions. It's also not clear exactly how much virus is needed for a productive SARS-CoV-2 infection, Banerjay said, with more research needed. It's still going to die very quickly in the environment.". People in the US wont face a shutdown like the one currently in place in Shanghai, where no one is allowed to leave their residential compounds, Covid testing is mandatory and food supplies are running low. CNN: What about outdoors? *** Seven days was chosen for this analysis, because 75% of cases occurred 7 days after the index date. First, what is the Covid-19 risk in your community? In this investigation, a confirmed case in a household contact was defined as having received a positive SARS-CoV-2 nucleic acid amplification test result or antigen test result 14 days after the index date (date of the index patients symptom onset or positive SARS-CoV-2 nucleic acid amplification test result or antigen test result), and a probable case in a household contact was defined as the presence of COVID-19compatible symptoms during the same 14-day period but without a positive SARS-CoV-2 test confirmation. Based on the data from the Gauteng province alone, the Omicron variant transmissibility compared to SARS-CoV-2 ancestral and Delta variant were 100.3% and 36.5%, respectively. Index patients were defined as the first person within each household to recently experience COVID-19compatible symptoms or have a positive SARS-CoV-2 test result. Thats different if you are immunocompromised or live with someone who is elderly with multiple medical conditions. How should people weigh which precautions they want to follow? "We were never safe from getting infected with a virus outdoors, it was just less likely," said Dr. Blaivas. Linking to a non-federal website does not constitute an endorsement by CDC or any of its employees of the sponsors or the information and products presented on the website. Its no surprise, then, that more and more stories have emerged of people speculating that they caught COVID-19 outside, which can be a bit unsettling to hear as cases continue to rise in many parts of the country. Experts Are Excited About a New COVID TreatmentHeres What to Know About It. Persons without symptoms and who did not have a positive SARS-CoV-2 test result were not considered to have a case of COVID-19. But are new subvariants changing that? Persons with sequence-confirmed Omicron infection and their household contacts were interviewed. The symptoms arent always as similar as you might think. In fact, it "could likely be more risky than an indoor setting under different circumstances with proper social distancing and other preventive measures," he added. . To Patel, for small group settings to be safe, people cant be shouting (COVID spreads more when people are singing or yelling), you must be able to maintain some distance from others, and everyone should be following public health measures like hand-washing. Once you head inside, especially in packed areas with low air turnover, there tends to be high transmission of the virus, so plan accordingly. Persons with sequence-confirmed Omicron variant infections during November 2021February 2022 were identified from four U.S. jurisdictions (Chicago, Illinois; Connecticut; Milwaukee, Wisconsin; and Utah) and contacted by telephone to assess eligibility of the household to participate in the investigation. A household was eligible if the index patient did not live in a congregate setting and did live with at least one other person for most of their potentially infectious period, defined as 2 days before through 10 days after the index date (the date of the index patients positive SARS-CoV-2 nucleic acid amplification test result or antigen test result or symptom onset, whichever occurred first). Second, the investigation relied primarily on self-reported data. Wen: The risk of outdoor transmission is very low to the point that its virtually nonexistent. The following conversation has been lightly edited for length and clarity. California's winter COVID-19 surge intensified Wednesday, with new overall coronavirus cases likely tied to holiday gatherings spiking up, along with confirmed cases of the Omicron strain. My husband and I are vaccinated and boosted. Part of HuffPost Wellness. Linsey Marr, a researcher on the airborne transmission of viruses like SARS-CoV-2 and a professor at Virginia Tech, agreed that the results show Omicron seems to survive better, which could be contributing to its heightened transmissibility. As the United States navigates a third year of the Covid-19 pandemic, cases are rising modestly in the Northeast, Philadelphia has reinstituted an indoor mask mandate and some colleges are requiring masks during the final days of the spring semester. Having COVID more than once can increase your risk of hospitalization and long COVID. The omicron sub-lineages are so new that infectious disease experts are still measuring their potential impact, even in outdoor settings. Dr. Rohde says nothing has fundamentally changed after omicron, except for peoples general attitudes about the pandemic. That leaves it mostly to individuals to protect themselves. Being outside would be lower exposure risk than being indoors, even with good ventilation and filtration; both of those options would be lower risk than being indoors with poor ventilation or filtration. The first is arming yourself with information about community levels in the area to which you're traveling; the CDC's community levels tracker can give you county-by-county information on hospital admissions and COVID-19 case counts. Similar ARs were observed across age groups for household contacts, including those aged 04 years (51.2%, 21 of 41). "This might affect the balance of transmission routes favouring more fomite transmission than we saw before," she said. It again depends on whats going on in your community, what your medical situation is, and how much you want to keep avoiding Covid-19. But the same factors that make indoor settings riskycrowded spaces, poor air circulation, the sharing of food and drinkcan also increase your chances of contracting COVID outside. Finally, this investigation occurred during a period when testing and sequencing capacity was strained and when many persons traveled and attended gatherings, increasing the possibility that household contacts had unknown SARS-CoV-2 exposures outside the home (6). Yes, you can catch BA.5 outside, but its more likely that youll catch it indoors than outdoors. How to Protect Yourself During Outdoor Events, CDC Stops Reporting COVID-19 Cases on Cruise ShipsHere's How You Can Still Stay Safe, COVID-19 Boosters Are Being Updated To Target Omicron SubvariantsHere's Why, What to Know About COVID Reinfections as BA.5 Cases Continue to Rise, Omicron BA.4 and BA.5 Symptoms: What To Know, BA.2.75 Is the Newest Omicron SubvariantHere's What We Know So Far. Although it makes sense that people would worry about getting a more contagious variant outdoors, it's likely that the current surge in cases doesn't have anything to do with outdoor spread. Vaccination status was not always verified, and the analysis did not account for potential variations in prevention practices (e.g., frequency of mask use). In addition, surfaces may play a greater role in Omicron transmission. The more crowded an outdoors space is, the more it begins to mimic an indoor space in terms of our exposure to shared air.. In order to outcompete, successful COVID variants have become more transmissible with time. And the omicron variant acquires a more effective coating than the delta variant, meaning it could stay infectious outside the body for longer. Of the 562 households successfully contacted, 175 (31.1%) declined to participate, and 204 (36.3%) were excluded; 183 (32.6%) were enrolled. Enrolled households included 183 index patients and 439 household contacts (Table). MMWR Morb Mortal Wkly Rep 2022;71:14652.

P-values comparing differences in stratum-specific ARs were calculated using a generalized estimating equation approach to account for clustering by household (2). The CDC doesn't currently recommend wearing a mask outdoors. But there are some people who want to avoid it at all costs and others who accept that if they engage in travel, resume parties, dine in restaurants and engage in other pre-pandemic activities, they will have some level of risk. https://www.medrxiv.org/content/10.1101/2021.12.27.21268278v1, https://www.medrxiv.org/content/10.1101/2022.01.09.22268984v1, https://www.medrxiv.org/content/10.1101/2021.08.16.21262121v2. However, if you live in a cold locale as she does, you may want to leave your mask on for warmth. Outdoors Lower Risk Well-ventilated indoors Moderate Risk Poorly ventilated indoors Higher Risk . MedRxiv: "Transmission event of SARS-CoV-2 Delta variant reveals multiple vaccine breakthrough infections." Experts warn omicron variants can spread more easily outdoors; prior infections provide less immunit. How can I reduce my risk of getting COVID-19? All HTML versions of MMWR articles are generated from final proofs through an automated process. The XBB.1.5 variant is a highly transmissible descendant of omicron that is now estimated . And while it is known that BA.4 and BA.5 are more transmissible than other variants, it is not yet clear if they are spreading outdoors any more than other variants. A confirmed case in a household contact was receipt of a positive SARS-CoV-2 nucleic acid amplification test result or antigen test result (through local or home testing) reported 14 days after the index date. For others, a restaurant with an open wall is outdoors. ** Persons provided retrospective information about any SARS-CoV-2 testing that they chose and were able to perform. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. CNN: Does it make sense to mask in some situations but not others? Ensuring you are able to distance even in an outdoor setting can only help reduce the risk of spread, Roberts stated. Wear a mask outdoors if you're going to be in close proximity to others. * Analysis of attack rates among HCs excluded persons with unknown case status or unknown categorization within a given stratum. These cookies may also be used for advertising purposes by these third parties. **** A negative SARS-CoV-2 test result was reported on the day of or after symptom onset by 38.8% (19 of 49) of household contacts classified as having probable COVID-19 and 68.6% (140 of 204) of those classified as not having COVID-19. * These authors contributed equally to this report. Upping the ante is the fact that recent subvariants like BA.4 and BA.5 are the most immune-evasive yet, with the ability to dodge antibodies from both vaccines and prior infection. Regular testing after potential exposure and remaining up to date on vaccines and boosters are also necessary steps, regardless of whether you're indoors or outdoors. "You're never going to find that much virus in a small area that you touch," he said. Someone who coughed onto their hand and then touched a door could seed virus there and transmit it to you if you touch. How Omicron spreads so fast is the question of the moment. Zeger SL, Liang KY, Albert PS. You can bring back some things that are lower risk or higher value but still take some precautions. Patel stressed that if youre going to crowded outdoor events like weddings, sports games and entertainment events, you should follow health precautions while we wait on data about the current subvariants spread outdoors. What are the implications for public health practice? You can review and change the way we collect information below. Vaccinated residents with breakthrough infections were significantly less likely to transmit them: 28% versus 36% for those who were unvaccinated. "So the safest place you can be [with other people] is still going to be outdoors," she says. Received a booster dose was defined as having received an additional dose after completion of the primary COVID-19 vaccination series before the index date. What Is the C.1.2 Variant in COVID-19 Cases? . Experts say consider a mask outdoors if the space is crowded. In just over five months, there were 22,334 confirmed SARS-CoV-2 Omicron infections, 31 hospitalizations and no COVID-19 deaths. Most index patients (88.4%, 152 of 172) and household contacts (78.7%, 140 of 178) with confirmed cases reported COVID-19compatible symptoms. Interviewers encouraged household contacts who had not received testing to receive testing if the telephone interview occurred 14 days after the index date and instructed them to call back with test results. The New York Metropolitan Transit Authority (MTA), which oversees subways and buses and lost billions of dollars in passenger revenue in 2020, spent $484 million last year in its response to. Persons were provided with the following list of signs and symptoms compatible with COVID-19: fever or chills, cough, shortness of breath or difficulty breathing, fatigue, muscle or body aches, headache, new loss of taste or smell, sore throat, congestion or runny nose, nausea or vomiting, and diarrhea or abdominal pain during the course of their recent illness. Once a saver, always a saver: Warren Buffett says generational wealth isnt what it used to be in his annual letter Its bigger than the housing crisis: An influential economist just blamed NIMBYs for American decline, and Elon Musk CA Notice at Collection and Privacy Notice, Do Not Sell/Share My Personal Information. Subanalyses focusing on secondary household transmission demonstrated a similar interval (median=3 days, IQR=25) (Supplementary Figure 1, https://stacks.cdc.gov/view/cdc/114723) and similar patterns in ARs (Supplementary Figure 2, https://stacks.cdc.gov/view/cdc/114722). . If you are sick and need to be around others, or are caring for someone who has COVID-19, wear a mask. If one person was wearing a mask, the risk of transmission isdecreased, and if both people were wearing masks, the risk issubstantially decreased. Omicron contains troubling characteristics that might make it more transmissible particularly among people who have already gotten and recovered from Covid, according to the WHO. She is also author of Lifelines: A Doctors Journey in the Fight for Public Health.. Third, how important is it to you to continue to avoid Covid-19? Experts believe the virus that causes COVID-19 spreads mainly from person to person. Slightly less transmissible were the 1918 pandemic strain of flu, which had an estimated R0 of 2, as does Ebola. The Omicron variant of the coronavirus appears to have spread between two fully vaccinated people who were staying in separate rooms across the hall from each other in a Hong Kong quarantine. Health and Human Services. CNN: Should people avoid indoor gatherings, knowing that outbreaks can happen? Fully vaccinated was defined as completion of the primary vaccination series 2 weeks before the index date and stratified into completion <5 months or 5 months before the index date. "If you are young and healthy or fully immunized, BA.5 may still make you feel pretty rotten for a while and some people can get very sick from it, so know your risks.". The protective measures we talked about early in the pandemic still work against Omicron. Julia M. Baker, PhD1,2,*; Jasmine Y.

Even small quantities of the virus floating around could infect you if you are not wearing a mask, said Dr. Janak Patel, director of the Division of Infectious Disease and Immunology at the University of Texas Medical Branch, adding that this could be the case for certain outdoor settings, too a situation that was generally considered OK for the past two-plus years of the pandemic. So called stealth Omicron, nicknamed for its ability to evade detection on PCR tests, was about 1.4 times more transmissible than BA.1, so its reproductive rate was around 13.3, Adrian Esterman, a professor of biostatistics and epidemiology at the University of South Australia, recently wrote on academic news website The Conversation. Some persons who were fully vaccinated had unknown dates for completion of their primary vaccination series. No, thankfully. These findings are subject to at least six limitations. For those hosting events, Majumder recommended decreasing the amount of attendees at gatherings, a move that can drastically reduce transmission. It's unlikely that Omicron is selectively targeting children, but because the variant is so.

But BA.5s heightened transmissibility will ultimately lead to more indoor and outdoor spread. The risk of outdoor transmission is exponentially lower than indoor transmission, and a well-ventilated, less crowded space also has much lower risk than people packed together in an unventilated space. "Most people that get it outdoors are still getting into groups with friends, neighbors and family when outdoors and that is a good way to spread infection when it is present," he said. The Centers for Disease Control (CDC) recommends that you get tested 5-7 days after "close contact with a person with suspected or confirmed COVID-19." The CDC defines close contact as being less than 6 feet away from an infected person for a total of 15 minutes or more over a 24-hour period. According to the latest data from the Centers for Disease Control and Prevention (CDC), BA.5 accounts for 65% of all COVID-19 cases in the U.S.; in just two months, the subvariant managed to outcompete BA.2 and BA.2.12.1the two previously dominant subvariants. The 15-minute rule no longer applies. **** Case status of household contacts was unknown if the occurrence of COVID-19compatible symptoms was not known and if the contacts testing results were unknown. It also helps to evaporate the liquid droplets in which it is. Lynn E. Sosa reports being a past Council of State and Territorial Epidemiologists STD Subcommittee chair. A CDC study showed how a surgical mask could reduce risk of exposure to the wearer by nearly 65% by double-knotting the loops and tucking in the sides of the mask to close gaps. Since COVID-19 is transmitted through contact with respiratory fluids carrying the infectious SARS-CoV-2 virus, a person can be exposed by an infected person coughing or speaking near them. 45 C.F.R. According to the Centers for Disease Control and Prevention (CDC), the subvariant is causing approximately 65% of the countrys COVID-19 cases at the time of publication.
