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. If multiple factors below indicate higher transmission risk, you should consider adding more prevention actions. Centers for Disease Control and Prevention. 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. Mohammad ShajahanAnadolu Agency/Getty Images, LinkedIn has officially entered its cringe era, and its working. Roberts stressed that COVID spread outdoors is much less common than spread indoors, but nothing is perfect. 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. All information these cookies collect is aggregated and therefore anonymous. As statistics show, the highest rate of COVID-19 transmission occurs in indoor settings. Why it may be harder to catch COVID-19 from surfaces than we first thought, Acknowledge COVID-19 is airborne, Lancet report urges as more evidence mounts, Omicron subvariant BA.2 raises new questions about puzzling evolution of virus behind COVID-19, Why an Omicron infection alone might not offer the immune boost you'd expect. If one person was wearing a mask, the risk of transmission isdecreased, and if both people were wearing masks, the risk issubstantially decreased. "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. 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. Earlier studies showed that the fewer cases of outdoor transmission almost always occurred during prolonged, close contact. Total coronavirus infection numbers remain low in Japan. Cookies used to make website functionality more relevant to you. A sharp spike in coronavirus cases, in part fueled by the new Omicron variant, is prompting health experts to urge that New Year's Eve gatherings be toned down. "We've been so focused on airborne transmission and masks that, maybe, we've kind of neglected to wash our hands," Marr said. MedRxiv: "Transmission event of SARS-CoV-2 Delta variant reveals multiple vaccine breakthrough infections." Were hearing anecdotal reports of people testing positive who think they got it outdoors, said Dr. Scott Roberts, associate medical director of Infection Prevention at Yale New Haven Hospital. Two jurisdictions attempted to contact all households on their line lists, and two jurisdictions attempted to contact households on their line lists based on specimen collection date. Lets say you work in a well-ventilated office, everyone around you is vaccinated, and you are well-distanced from the next person. BA.5the omicron subvariant that emerged in South Africa in February before sweeping across the worldis now the dominant coronavirus variant in the United States. Heres what experts know and dont know about COVID spread outdoors: At this point, we are very familiar with uncertainty when it comes to COVID. The study authors themselves did note the limitations at play, including the controlled, lab-based setting and differences in the droplets used in the research compared to respiratory droplets, which may all impact the stability of the virus. "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.". But that doesn't mean that being outdoors isn't going to. The estimated overall AR in this investigation is consistent with the range of ARs observed in other Omicron transmission studies (3), and higher than those associated with some other SARS-CoV-2 variants. These findings underscore the importance of implementation of multicomponent prevention measures for reducing SARS-CoV-2 transmission in household settings, including from the Omicron variant (4). URL addresses listed in MMWR were current as of
It's still going to die very quickly in the environment.". First, what is the Covid-19 risk in your community? "The extra virus stability on surfaces may be one possible factor and should be taken into consideration when recommending control measures against the infection.". Omicron subvariant BA.5 may be the most contagious version of the SARS-CoV-2 virus that we've seen yetand even situations that have seemed relatively low-risk as of late, like outdoor gatherings, may now pose a greater threat. Dr. Mallika Marshall explains: Omicron subvariants BA.4 and BA.5 are highly transmissible, some say as transmissible as measles, which is considered the most infectious viral illness in humans. This was true for the other variants too, Linsey Marr, PhD, a professor of civil and environmental engineering at Virginia Tech who studies viral transmission, tells SELF. S&P Index data is the property of Chicago Mercantile Exchange Inc. and its licensors. The median interval between index date and date of interview was 24 days (IQR=1729 days). The SARS-CoV-2 B.1.1.529 (Omicron) variant contributed to a surge of SARS-CoV-2 infections in the United States during December 2021January 2022. Please note that CBC does not endorse the opinions expressed in comments. MMWR Morb Mortal Wkly Rep 2022;71:14652. "The risk of transmission is much lower . 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. Even past infection or immunization don't offer quite as much protection as would be expected. 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. Roberts stressed that COVID spread outdoors is much less common than spread indoors, but nothing is perfect. The XBB.1.5 variant is a highly transmissible descendant of omicron that is now estimated . check the Centers for Disease Control and Prevention. SARS-CoV-2 B.1.1.529 (Omicron) Variant Transmission Within Households Four U.S. Jurisdictions, November 2021February 2022. For others, a restaurant with an open wall is outdoors.

If its in green or yellow or low or medium risk you could choose not to, depending on the other two factors. The protective measures we talked about early in the pandemic still work against Omicron. My husband and I are vaccinated and boosted. Other members of the scientific and medical community also had mixed views on what this new study actually tells us about how Omicron spreads. "It appears that outdoor transmission has become more likely with the newer variants over the past year (i.e., since delta) as they have become more transmissible, but outdoors remains a much. You will be subject to the destination website's privacy policy when you follow the link. So attending a tightly packed outdoor concert and sharing your drink with a friend tends to lend itself to a higher transmission risk than, say, a park picnic in an open space with a couple of friends who arent sitting close to you. Arinjay Banerjee, a virologist working with the University of Saskatchewan's Vaccine and Infectious Disease Organization, echoed that. Early contact tracing studies detected far more indoor transmission of the coronavirus than outdoor. Dr. Rohde says nothing has fundamentally changed after omicron, except for peoples general attitudes about the pandemic. See what it's like. Rodney E. Rohde, PhD, a virologist and professor of clinical laboratory science at Texas State University, tells SELF that many people have seen the outdoors as a get out of jail free cardbut that has never really been the case. "The risk outside is going to be substantially less. 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. Overall, engaging in outdoor activities is less risky than going to indoor venues. they should expect rapid transmission of COVID-19 that will prevent students . Lane . "I think we shouldn't drop our guard against SARS-CoV-2, period.". BA.5's mutations have also allowed it to sneak past the body's immune system more easily. cases are rising modestly in the Northeast, Philadelphia has reinstituted an indoor mask mandate, BA.2 is a subvariant of the Omicron variant. COVID-19 still can be transmitted in outdoor settings . Household contacts were defined as any persons who spent one or more overnights in the residence with the index patient during their potentially infectious period. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. 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. 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. These findings are subject to at least six limitations. And playing outdoors, Malani notes, is great for kids building snow structures and sledding in parts of the country that are now shivering in winter temperatures. Masks work very well, though here I would urge that people wear an N95 or equivalent mask, such as a KN95 or KF94. Outdoor airflow has done a good job dispersing pathogens. Omicron transmission occurred in 124 (67.8%) of 183 households. More information is available, Travel requirements to enter the United States are changing, starting November 8, 2021.

The short answer here is yes, you can get infected with the BA.5 subvariant, even in outdoor settings. 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. Greater COVID transmissibility due to Omicron variants means greater transmissibility in any setting, indoors or outdoorseven if outside is still safer, experts say. 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. These are all reasonable decisions depending on how you think about your own risk. For those hosting events, Majumder recommended decreasing the amount of attendees at gatherings, a move that can drastically reduce transmission. You'll also want to consider your own personal risk for COVID-19, that of those close to you, and your combined risk tolerance for public situations. 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. New research is pointing to the answer, 2 years into the pandemic, burning questions remain about COVID-19 and how we fight it, scientific consensus began to crystallize, CBC's Journalistic Standards and Practices.

But that shouldn't cause you to lose sight of the advantages of socializing outdoors, she adds. 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. Some persons who were fully vaccinated had unknown dates for completion of their primary vaccination series. The second thing to think about is, what is your medical situation and the circumstances of others in your household? Serial intervals and household transmission of SARS-CoV-2 Omicron variant, South Korea, 2021. What if you have to go back to the office, and others arent masking? CDC COVID-19 Response Team. 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). "Doing experiments inside a lab where humidity is controlled is one thing. Still, he says, you have to be close to the infected person or downwind of them. . The CDC doesn't currently recommend wearing a mask outdoors. "When a variant is slated to be more or less transmissible than another, it applies as a blanket statement regardless of setting,'' said Dr. Weissenbach. Corresponding authors: Julia M.

"This might affect the balance of transmission routes favouring more fomite transmission than we saw before," she said. 2023 CBS Broadcasting Inc. All Rights Reserved. When possible, SARS-CoV-2 testing data were supplemented with or verified using state or jurisdiction registry data. At that time, the World . Persons with sequence-confirmed Omicron infection and their household contacts were interviewed. No, thankfully. Data were collected and managed using REDCap (version 11.1.8; Vanderbilt University) and analyzed using R (version 4.0.3; R Foundation).

"So the safest place you can be [with other people] is still going to be outdoors," she says. The 15-minute rule no longer applies. Subanalyses were conducted to examine potential secondary transmission (as opposed to all household transmission); the interval was calculated for households of two persons (index patient and another household contact), and ARs were calculated after restricting the case definition to cases identified 7 days*** after the index date. Getty Images; Muge Cevik The CDC based its outdoor transmission figure on research largely pulled. Namely, we have vaccines and boosters, which protect very well against severe illness and also reduce the risk of Covid-19 infection. 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. Slightly less transmissible were the 1918 pandemic strain of flu, which had an estimated R0 of 2, as does Ebola. "If you're standing outside, shoulder-to-shoulder with hundreds of unmasked strangers [for an extended period of time], it certainly has the potential to mimic a cramped, indoor setting," said Dr. Weissenbach. 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. She has written about COVID-19 for many publications, including The New York Times, Kaiser Health News, Medscape and The Washington Post. According to an Epidemiological Update from the European Centre for Disease Prevention and Control (ECDC), "the current growth advantage for the BA.4 and BA.5 variants of concerncompared to the dominant variant BA.2 is probably due to their ability to evade immune protection against infection induced by prior infection and/or vaccination, particularly if this has waned over time." The information in this story is what was known or available as of publication, but guidance can change as scientists discover more about the virus. When Should You Test (and Possibly Retest) After Being Exposed to COVID-19? 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.
