Should You Be Worried About Outdoor Transmission During the BA.5 Surge? Heres how that might affect crucial funding, access to tests, and case counts. Centers for Disease Control and Prevention. Persons reported their race (White, Black, Asian, American Indian or Alaska Native, or Native Hawaiian or other Pacific Islander) and ethnicity (Hispanic/Latino or non-Hispanic/Latino) from lists of options and had the opportunity to state another option if their race or ethnicity was not listed. Analysis of AR among household contacts excluded eight persons with unknown case status (persons for whom it was not known whether COVID-19compatible symptoms were present and whether SARS-CoV-2 testing had occurred [or if testing occurred, the results were unknown]). That means the exact timings might not pan out for people living their daily lives, though Marr did feel the comparison between the ancestral virus and Omicron was notable. We are in the midst of another COVID-19 wave driven by the highly contagious BA.4 and BA.5 variants, which have a mutation in the spike protein of the coronavirus that causes these variants to more easily attach to (and infect) people. Emanuel Goldman, a microbiology professor at the New Jersey Medical School of Rutgers University, said in an article published in The Lancet journal in 2020 that the risk of COVID-19 infection from surfaces at that time was "exaggerated.". Omicron transmission occurred in 124 (67.8%) of 183 households. Coronavirus FAQ: Why are some folks hacking home COVID tests by swabbing their throat. Multicomponent COVID-19 prevention strategies, including up-to-date vaccination, isolation of infected persons, and mask use at home, are critical to reducing Omicron transmission in household settings. Fourth, the interval analysis reflected time between dates of a positive test result or symptom onset, not date of infection, and did not account for duration of symptoms and prevention strategies, such as frequency of mask use. Peter Kneffel Its a nasty stomach bugand cases have been rising since August. "If you wash your hands not obsessively, but just thoughtfully and carefully that's going to reduce any transmission you see out there," Evans said. Household contact ARs ranged from a low of 47.5% (19 of 40) when the index patient was aged 511 years to a high of 72.0% (18 of 25) when the index patient was aged 04 years. Omicron BA.5 May Increase the Risk of Outdoor TransmissionHere's How to Stay Safe Although being outdoors is overall the safer option, when a virus is more contagious, it's more contagious. That will reduce not only this coronavirus transmission but other respiratory and gastrointestinal pathogens, too. Earlier studies showed that the fewer cases of outdoor transmission almost always occurred during prolonged, close contact. The median interval between index date and date of interview was 24 days (IQR=1729 days). Abbreviations: Full = fully vaccinated; HC = household contact; IP = index patient; Partial = partially vaccinated; Unvacc = unvaccinated. And while things are admittedly looking up, infection rates are low and (in many locations . Omicron may hang around longer on surfaces than original virus, early findings suggest | CBC News Loaded. Yet Omicron, the highly contagious variant known for slipping around some of our best defences, 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. Here, experts discuss just how contagious BA.5 isand how you can go the extra step to protect yourself, even during outdoor activities this summer. and/or the original MMWR paper copy for printable versions of official text, figures, and tables. But he warned the public not to panic, and avoid resorting to heavy-handed precautions. Experts believe the virus that causes COVID-19 spreads mainly from person to person. All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest. See the Interactive Home Ventilation Tool. Early contact tracing studies detected far more indoor transmission of the coronavirus than outdoor. All information these cookies collect is aggregated and therefore anonymous. The omicron sub-lineages are so new that infectious disease experts are still measuring their potential impact, even in outdoor settings. It's also not clear exactly how much virus is needed for a productive SARS-CoV-2 infection, Banerjay said, with more research needed. On February 25, 2022, this report was posted online as an MMWR Early Release. Sect. It's unlikely that Omicron is selectively targeting children, but because the variant is so. Lets say you work in a well-ventilated office, everyone around you is vaccinated, and you are well-distanced from the next person. These cookies allow us to count visits and traffic sources so we can measure and improve the performance of our site. Households with high transmission or with more attention to public health measures may have been more likely to participate. Total coronavirus infection numbers remain low in Japan. A variety of newsletters you'll love, delivered straight to you. 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. Yes, you can get BA.5 outdoors, but you could also contract other COVID variants outside, says Thomas Russo, M.D., professor and chief of infectious disease at the University at Buffalo in New. Roberts added that since BA.5 is more transmissible than prior variants indoors, it is likely that its more transmissible outdoors, too. Thats different if you are immunocompromised or live with someone who is elderly with multiple medical conditions. Masks are still effective at protecting you against COVID-19 even if you're the only person wearing one. When possible, vaccination data were supplemented with or verified using state or jurisdiction registry data. Five studies described influenza transmission outdoors and 2 adenovirus transmission outdoors. While outdoor events are safer than indoor events, theyre not 100% safe, Majumder told the news outlet. 2023 CBS Broadcasting Inc. All Rights Reserved. FORTUNE is a trademark of Fortune Media IP Limited, registered in the U.S. and other countries. Though the BA.5 wave hasnt caused a significant spike in hospitalizations or deaths in South Africa, certain locations hit by BA.5, like Portugal, have seen an uptick in hospitalizations. Overall, the ECDC said this makes more frequent breakthrough infections and reinfections possible with BA.4 and BA.5. "The risk outside is going to be substantially less. Partially vaccinated was defined as having only 1 dose of a 2-dose series or completing the primary vaccination series <2 weeks before the index date. Fresh air disperses and dilutes the virus. Sunlight and humidity, for instance, can both contribute to how long viruses are able to survive on surfaces outdoors, he noted.

Box 500 Station A Toronto, ON Canada, M5W 1E6. Nevertheless, in its coronavirus profile, the RKI also posits that "overall, transmissions outdoors rarely occur. Roberts stressed that COVID spread outdoors is much less common than spread indoors, but nothing is perfect. Users are referred to the electronic PDF version (https://www.cdc.gov/mmwr) 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. Thanks to a unique cluster of mutations on the spike protein, the part of the virus that latches to our cells, BA.5 is believed to be the most contagious strain of SARS-CoV-2, the virus that causes COVID-19, so far. Is BA.2 so contagious that it could transmit there? 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. Mutations and natural selection can help subsequent versions of a virus get stronger and stronger in different ways, which seems to be happening with the Covid-19 coronavirus. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Although outdoor settings are overall the safer option, when a virus is more contagious, it's more contagious in any setting. / CBS Boston. A simple cloth mask is much less effective, especially against a variant as contagious as BA.2. ARs among household contacts were estimated overall, by household contact characteristics, and by index patient characteristics, by dividing the number of household contacts with confirmed and probable cases by the total number of household contacts within a given stratum. Persons with probable cases included symptomatic persons who did not have SARS-CoV-2 testing and symptomatic persons who received negative SARS-CoV-2 test results. How should people weigh which precautions they want to follow? At this point, the definition of outdoors isnt exactly agreed upon, Roberts noted. Wind is typically good because it will lead to more rapid dilution [of particles], but you should pay attention to wind direction and avoid being close and directly downwind of others, Dr. Marr says. "More evidence is needed to account for the increased transmissibility of (Omicron) observed in various community studies," the researchers wrote. Study participants who contributed their time and information; Olivia Almendares, Sarah E.

Even if you cant take time off, you can still take care of yourself. We also have more tools at our disposal than we did in 2020. P-values comparing differences in stratum-specific ARs were calculated using a generalized estimating equation approach to account for clustering by household (2). Cleaning hands at . . Among 431 household contacts, 227 were classified as having a case of COVID-19 (attack rate [AR] = 52.7%). If you are sick and need to be around others, or are caring for someone who has COVID-19, wear a mask. 552a; 44 U.S.C. Depending on the outdoor situation youre in, it changes the ventilation dynamics of that area and can alter the risk of COVID for people in that [space], Roberts said, adding that hed feel pretty comfortable in a socially distant, outdoor setting with nothing covering the space (like tents, tarps, overhangs, and enclosures) even with the BA.5 variant. CNN: Should people avoid indoor gatherings, knowing that outbreaks can happen? "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 outdoors have always been a sanctuaryeven more so since the advent of the pandemic. Iuliano AD, Brunkard JM, Boehmer TK, et al.

So some people may want to mask up in certain outdoor situations. Researchers have said that while Covid infections can happen outdoors, the chances are massively reduced. Dr. Dumois: The Omicron variant is far more contagious than anything we ve seen with this coronavirus, so this is very much a different virus than any of the variants we have seen before. If it was unclear who within the household was the index patient (e.g., if multiple persons developed COVID-19compatible symptoms in the household on the same day or had the same SARS-CoV-2 exposure) or if household contacts had confirmed or probable cases and were known to have a SARS-CoV-2 exposure to someone other than the index patient, the household was excluded from analyses. Someone who coughed onto their hand and then touched a door could seed virus there and transmit it to you if you touch that door and then your nose or mouth. And, if you dont feel well, stay home. Zeger SL, Liang KY, Albert PS. Vaccination status was not always verified, and the analysis did not account for potential variations in prevention practices (e.g., frequency of mask use). Now, since everyone is spending more time outside because of summer and there is a very transmissible virus circulating, people may be getting infected with BA.5 outdoors more frequently. Its all about how close you are to that person coupled with airflow [turnover] and ventilation of the space you are in, whether that is indoors or outdoors, Dr. Rohde says. Age at index date was determined from date of birth or self-reported age. Slightly less transmissible were the 1918 pandemic strain of flu, which had an estimated R0 of 2, as does Ebola. Experts say outdoor transmission has always been a thingwith alpha, delta, omicron, and now BA.5. Age at index date was determined from date of birth or self-reported age. That's a key finding from a new pre-print paper from researchers at the University of Hong Kong's school of public health, which is published online but has not yet been peer-reviewed. For others, a restaurant with an open wall is outdoors. 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. 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. The AR among household contacts with previous SARS-CoV-2 infection was 40.9% (9 of 22) compared with 59.8% (183 of 306) among those without previous infection (p-value=0.08).

Vaccinated residents with breakthrough infections were significantly less likely to transmit them: 28% versus 36% for those who were unvaccinated. If your own risk tolerance is low, certain outdoor situations could call for masking up. 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. But the likelihood of transmission grew by 6% for every five weeks . 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. (The other layers are vaccination, masks and physical distancing.). This conversion might result in character translation or format errors in the HTML version.

CNN: What if you have to go back to the office, and others arent masking? See the Interactive Home Ventilation Tool. Some will think those activities are worth the risk. 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. ARs were consistently high across household contact and index patient age groups, including those aged 04 years. Risk is also lower if the mask or respirator is a type that offers greater protection. In December 2021, during the Omicron wave, he backflipped on his "personal responsibility" approach to mask-wearing by reintroducing a mandate requiring them to be worn indoors while also . Wen: The risk of outdoor transmission is very low to the point that its virtually nonexistent. Without sequencing results for all household contact cases, it was not possible to confirm that transmission occurred from index patients to household contacts or that household contacts were infected with the same variant. It's nice to see people's expressions and feel a sense of normalcy.". 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. Dr. Leana Wen: BA.2 is a subvariant of the Omicron variant. Building off other recent research which showed Omicron's heavily-mutated spike protein is more stable than the ancestral strain, and their own previous findings on SARS-CoV-2's level of infectiousness on various surfaces, the Hong Kong team explored what would happen if droplets containing Omicron the BA.1 lineage, specifically were applied to surfaces like stainless steel, paper, and glass.
