Mounting evidence suggests coronavirus is airborne — but health advice has not caught up 2020-07-07T04:00:00Z Professor Babak Javid, an infectious disease consultant at Cambridge University Hospitals, said airborne transmission of the virus is possible and even likely, but said evidence over how long the virus stays airborne is lacking. WHO reviewing report urging new guidance over airborne spread of coronavirus 2020-07-06T04:00:00Z The authors cited previous studies suggesting that germs closely related to the new virus were spread via airborne transmission. Scientists urge WHO to acknowledge virus can spread in air 2020-07-06T04:00:00Z A group of 239 scientists from 32 different countries plan on publishing a letter in a scientific journal next week contending that the coronavirus is far more predisposed to airborne transmission than previously believed. Coronavirus may spread through air much more readily than we thought 2020-07-06T04:00:00Z The article, published Saturday, reported that 239 experts sent an open letter to the WHO detailing evidence of airborne transmission. Nearly 240 experts call for updated coronavirus WHO guidelines 2020-07-06T04:00:00Z The CDC doesn’t mention aerosols or airborne transmission, but it updated its website on 16 June to say that the closeness of contact and the duration of exposure is important. Mounting evidence suggests coronavirus is airborne — but health advice has not caught up 2020-07-07T04:00:00Z But airborne transmission is possible in some circumstances, such as when performing intubation and aerosol-generating procedures, the WHO says. WHO reviewing report urging new guidance over airborne spread of coronavirus 2020-07-06T04:00:00Z “The airborne transmission of the virus is increasingly of concern and masks are an effective way to prevent that. The more we learn about this virus, the more I’m encouraging people to wear masks.” If more Americans wore masks the pandemic would slow, experts say 2020-06-30T04:00:00Z But it was during that first foray into day care germs that she discovered how little was known about airborne transmission of viruses. The Scientist, the Air and the Virus 2020-06-12T04:00:00Z In an update as recent as June 29, the WHO said airborne transmission is “possible” in circumstances generating aerosols smaller than 5 microns, such as during medical procedures. Nearly 240 experts call for updated coronavirus WHO guidelines 2020-07-06T04:00:00Z It also said that airborne transmission was the primary way the virus spreads. Scientists Take Aim at Another Coronavirus Study in a Major Journal 2020-06-18T04:00:00Z But how often airborne transmission happens, which is unknown, also matters. WHO reviewing report urging new guidance over airborne spread of coronavirus 2020-07-06T04:00:00Z The potential for airborne transmission of infectious disease via sewage has been the subject of research for more than a century, and the toilet plume’s role has been scrutinized since the 1950s. Put a lid on it, folks: Flushing may release coronavirus-containing ‘toilet plumes’ 2020-06-16T04:00:00Z Environmental scientists may study waterborne pathogens or air pollution, but they don’t typically focus on airborne transmission of disease. The Scientist, the Air and the Virus 2020-06-12T04:00:00Z Lately, research and discussion has focused on airborne transmission over longer distances. As restaurants reopen, here’s what you should know about air conditioning, air flow and the coronavirus 2020-05-28T04:00:00Z Many scientists believe that social distancing is a big factor in reducing transmission of the virus, and that airborne transmission, while it may occur, is not the primary means by which the virus spreads. Scientists Take Aim at Another Coronavirus Study in a Major Journal 2020-06-18T04:00:00Z Officials at South Korea’s Centers for Disease Control said on Monday they were continuing to discuss various issues about COVID-19, including the possibility of airborne transmission. WHO reviewing report urging new guidance over airborne spread of coronavirus 2020-07-06T04:00:00Z Explanations other than airborne transmission are improbable, “especially when it’s happening in choir after choir after choir,” he said. Scientists to choirs: Group singing can spread the coronavirus, despite what CDC may say 2020-06-01T04:00:00Z As states across America being to reopen, some scientists are voicing fears about so-called "superspreaders" who may be responsible for larger numbers of coronavirus cases through airborne transmission. Some scientists fear ‘superspreaders’ may prompt new COVID-19 outbreaks as states reopen 2020-06-01T04:00:00Z Experts from Aalto University worked with the Finnish Meteorological Institute, VTT Technical Research Center of Finland and the University of Helsinki to investigate the airborne transmission and spread of coronavirus in indoor spaces. Creepy video shows how coronavirus droplets spread in indoor spaces 2020-05-27T04:00:00Z The explosive transmission on the Diamond Princess cruise ship, as well as other coronavirus outbreaks, constituted telltale signs that airborne transmission was happening. Opinion | We cannot keep ignoring the possibility of airborne transmission. Here’s how to address it. 2020-05-26T04:00:00Z The likelihood of airborne transmission—especially compared with other routes, such as droplets or surfaces—remains unclear. How Coronavirus Spreads Through the Air: What We Know So Far 2020-05-12T04:00:00Z “It strongly suggests that there is potential for airborne transmission.” Airborne Coronavirus Detected in Wuhan Hospitals 2020-04-28T04:00:00Z But researchers say the importance of potential airborne transmission, and the possible boosting role of pollution particles, mean it must not be ruled out without evidence. Coronavirus detected on particles of air pollution 2020-04-24T04:00:00Z In other words, Fouchier's research took a flu virus that did not exhibit airborne transmission, then infected a number of ferrets until it mutated to the point that it was transmissible by air. The pandemic has exposed the threat of a biowarfare arms race 2020-04-24T04:00:00Z Such super-spreader events appear to be happening exclusively indoors, where airborne transmission is more likely. Opinion | We cannot keep ignoring the possibility of airborne transmission. Here’s how to address it. 2020-05-26T04:00:00Z But even if there is airborne transmission, it may only happen at short range—within which other infection routes may be just as likely—or more so. How Coronavirus Spreads Through the Air: What We Know So Far 2020-05-12T04:00:00Z The researchers, for example, did not perform experiments to simulate the airborne transmission. How Coronavirus Infected Some, but Not All, in a Restaurant 2020-04-20T04:00:00Z Prof Jonathan Reid at Bristol University in the UK is researching airborne transmission of coronavirus. Coronavirus detected on particles of air pollution 2020-04-24T04:00:00Z But some scientists say there is preliminary evidence of airborne transmission — in which the disease spreads in the much smaller particles from exhaled air. Daily briefing: Coronavirus in sewage could reveal the true scale of the outbreak 2020-04-02T04:00:00Z But you probably haven’t heard anything about airborne transmission, which many organizations have largely ignored. Opinion | We cannot keep ignoring the possibility of airborne transmission. Here’s how to address it. 2020-05-26T04:00:00Z But experts that work on airborne respiratory illnesses and aerosols say that gathering unequivocal evidence for airborne transmission could take years and cost lives. Is the coronavirus airborne? Experts can’t agree 2020-04-01T04:00:00Z However, the WHO experts say, an analysis of more than 75,000 coronavirus cases in China revealed no cases of airborne transmission. You may be able to spread coronavirus just by breathing, new report finds 2020-04-02T04:00:00Z But the WHO recognizes in the context of coronavirus, “airborne transmission may be possible in specific circumstances and settings in which procedures or support treatments that generate aerosols are performed,” the newspaper reported. Coronavirus: Social distancing gap should be greatly increased, MIT researcher says 2020-03-31T04:00:00Z Linsey Marr, an environmental engineer at Virginia Tech and an expert on airborne transmission of viruses, said some people happen to be especially good at exhaling fine material, producing 1,000 times more than others. A choir decided to go ahead with rehearsal. Now dozens of members have COVID-19 and two are dead 2020-03-29T04:00:00Z One is that a mask is not seen as reliable protection, given that current research shows the virus is spread by droplets and not airborne transmission. Why some countries wear face masks and others don't 2020-03-25T04:00:00Z As long as we are sharing an airspace with someone else, breathing in the air that they exhale, airborne transmission is possible, says Tang. Is the coronavirus airborne? Experts can’t agree 2020-04-01T04:00:00Z The coronavirus spreads through droplets as well, researchers say, and it may be capable of airborne transmission too. The flu has killed far more people than coronavirus. So why all the frenzy about COVID-19? 2020-03-05T05:00:00Z Chopra’s team recently reported on fighting pneumonic plague - the most virulent type that spreads through airborne transmission. Researchers in Galveston use rodents for anti-plague tests 2016-11-06T04:00:00Z Providing heating, ventilation and air-conditioning, the system is integral to improving the hospital’s air quality and mitigating the airborne transmission of germs that could lead to infections. Decaying Long Island V.A. Hospital Closes Operating Rooms 2016-05-19T04:00:00Z In September, the lead author of the new study, Michael Osterholm, published an op-ed — condemned by some — indicating that airborne transmission Ebola is a possibility. Ebola limited airborne transmission ‘very likely’: analysis 2015-02-19T05:00:00Z The assumption should be that airborne transmission is possible unless experimental evidence rules it out, not the other way around, says Tang. Is the coronavirus airborne? Experts can’t agree 2020-04-01T04:00:00Z But he said that the likelihood of airborne transmission being a common occurrence remains very low. Ebola Transmission Through Cough Possible, But Not Likely: Experts 2015-02-19T05:00:00Z It’s spread by direct contact with nasal or throat secretions of infected people or by airborne transmission. Measles case reported in Sioux Falls; officials host clinic 2015-01-24T05:00:00Z It is spread by direct contact with nasal or throat secretions of infected people or, less frequently, by airborne transmission. 5 more measles cases reported in South Dakota 2014-12-31T05:00:00Z The White House is particularly concerned with research expected to create versions of those pathogens that increase airborne transmission. White House halts research into 'super strains' of infectious diseases 2014-10-20T04:00:00Z Officials say they understand how the virus is spread — direct contact with an infected person’s bodily fluids — and that talk of airborne transmission is unwarranted. Airborne Ebola outbreak in monkeys raises possibility virus could mutate 2014-10-16T04:00:00Z Still, they stressed that airborne transmission of Ebola -- similar to that which occurs with the flu or measles -- remains unlikely in the future, given that it would require the virus to undergo a substantial mutation. Ebola Transmission Through Cough Possible, But Not Likely: Experts 2015-02-19T05:00:00Z In spite of speculation, the UN Ebola Mission for Emergency Response says extensive studies of the virus have not shown any airborne transmission. How to avoid catching Ebola 2014-10-13T04:00:00Z Experts disagree over what to tell people about possibility the virus will mutate to become more contagious – or even evolve an airborne transmission route. A Flock of Black Swans; How To Think Clearly About The Unpredictable Hazard of Ebola 2014-10-07T04:00:00Z Generally speaking, this is what is meant by “airborne transmission.” Can Ebola Go Airborne? 2014-09-03T04:00:00Z “We are confident this is not airborne transmission.” Airborne Ebola outbreak in monkeys raises possibility virus could mutate 2014-10-16T04:00:00Z She emphasized that unlike influenza or tuberculosis, Ebola is not spread by airborne transmission of germs, only by contact with the bodily fluids of someone who is contagious. Health Officials Try to Quell Fear of Ebola Spreading by Air Travel 2014-08-14T04:00:00Z “Do we still need to consider the possibility of airborne transmission?” MERS Could Be Airborne, Research Indicates 2014-07-22T04:00:00Z The findings show the need for "further investigations and measures to prevent possible airborne transmission of this deadly virus," lead author Esam Azhar, said in a news release from the American Society for Microbiology. MERS Virus Found in Air in Camel Barn 2014-07-22T04:00:00Z But PEDv is expected to thrive again as the weather cools, and airborne transmission could further the virus's reach. Insight: Oklahoma winds may spread deadly swine virus 2013-09-20T05:36:10Z Rep. Michael C. Burgess, a Texas Republican and doctor, echoed those sentiments, saying thin evidence of airborne transmission does not worry him just yet. Airborne Ebola outbreak in monkeys raises possibility virus could mutate 2014-10-16T04:00:00Z Dr. Benoît Guéry, director of the Lille hospital’s infectious disease unit, said the second case suggested that airborne transmission was possible. France Confirms Second Case of Virus Linked to SARS 2013-05-14T00:28:54Z To their surprise, introducing either the H1N1 gene for the polymerase enzyme or the gene for the so-called nonstructural protein was sufficient to cause airborne transmission. Single Gene Swap Helps Bird Flu Virus Switch Hosts 2013-05-02T19:45:00Z The researchers say they believe that limited airborne transmission might be contributing to the spread of the disease in some parts of Africa. Concerns over 'in the air' Ebola 2012-11-16T00:50:04Z It did not kill the ferrets that caught it through airborne transmission, but it did kill when high doses were squirted into the animals’ nostrils. H5N1 Bird Flu Research That Stoked Fears Is Published 2012-06-21T18:05:14Z Therefore, investigations of routes of influenza virus transmission between animals and on the determinants of airborne transmission are high on the influenza research agenda. [Special Issue Report] Airborne Transmission of Influenza A/H5N1 Virus Between Ferrets 2012-06-21T18:26:51.147Z Proponents of continued research in this area suggest that knowing the mutations involved in mammalian airborne transmission will aid surveillance, allowing us to see whether there is evolution in the direction of a pandemic virus. [Special Issue Policy Forum] Evolution, Safety, and Highly Pathogenic Influenza Viruses 2012-06-21T18:26:35.197Z The study tested for airborne transmission of H5N1 by placing infected and uninfected ferrets in adjoining cages. [News & Analysis] Avian Influenza: Public at Last, H5N1 Study Offers Insight Into Virus's Possible Path to Pandemic 2012-06-21T18:25:09.037Z "The thought of airborne transmission is pretty frightening." Concerns over 'in the air' Ebola 2012-11-16T00:50:04Z The study provides “the first clues about what properties of the HA protein, other than receptor specificity, might be important for mammalian airborne transmission”, says Racaniello. Mutant-flu paper published 2012-05-02T17:20:17.937Z Reverse genetics will be needed to identify which of the five to nine amino acid substitutions in this virus are essential to confer airborne transmission. [Special Issue Report] Airborne Transmission of Influenza A/H5N1 Virus Between Ferrets 2012-06-21T18:26:51.147Z The studies, which created forms of H5N1 that can spread between ferrets through airborne transmission, are likely to be published in a few months. Research on Highly Contagious Avian Flu Now Likely to Be Published in a Few Months 2012-02-21T19:45:00.203Z Prior to publication, media reports suggested that airborne transmission required five mutations. [News & Analysis] Avian Influenza: Public at Last, H5N1 Study Offers Insight Into Virus's Possible Path to Pandemic 2012-06-21T18:25:09.037Z Currently, our knowledge of determinants of airborne transmission of influenza virus is virtually nonexistent. [Policy Forum] Public Health and BIosecurity: Restricted Data on Influenza H5N1 Virus Transmission 2012-02-09T19:25:34.200Z Infected terrestrial hosts usually exhale the organism continuously, making for highly efficient airborne transmission. ESP 2011-02-09T18:22:36.447Z Thus, avian A/H5N1 influenza viruses can acquire the capacity for airborne transmission between mammals without recombination in an intermediate host and therefore constitute a risk for human pandemic influenza. [Special Issue Report] Airborne Transmission of Influenza A/H5N1 Virus Between Ferrets 2012-06-21T18:26:51.147Z "There are documented instances of airborne transmission of pathogens from one space to another in buildings that use natural ventilation." 2008-08-13T18:23:00Z Because we did not measure particle size during our experiments, we will use the term “airborne transmission” throughout this Report. [Special Issue Report] Airborne Transmission of Influenza A/H5N1 Virus Between Ferrets 2012-06-21T18:26:51.147Z The specific mutations we identified in these experiments that are associated with airborne transmission represent biological traits that may be determined by a set of different amino acid substitutions. [Special Issue Report] Airborne Transmission of Influenza A/H5N1 Virus Between Ferrets 2012-06-21T18:26:51.147Z Although our experiments showed that A/H5N1 virus can acquire a capacity for airborne transmission, the efficiency of this mode remains unclear.
