Two recent studies have found that COVID outdoor transmission may be more likely than the Delta variant continues to spread by the population. The first paper, which is still waiting for peer review, describedA wedding in Texas in April. Even if the wedding took placeOutside under an outdoor tentA virus epidemic has led to six fully vaccinated people becoming infected and one more dying, salon reports.

The authors emphasize two people who had been negative for the variant before traveling from India, but have probably infected the other guests, who have all been tested later positive for the variant. They wrote: "Without vaccine breakthrough stories, this suggests that Delta variant may have immune escape in patients who received the Pfizer [Vaccine], Moderna-MRNA [Vaccine] and [the vaccine]". "

The second case in question concerns the Whiskey Music Fest, an outdoor concert held on July 10 in Oregon which has so far had64 covid infections connected to it. Although it is not clear how many of those who have contracted the virus have been vaccinated, state health leaders have launched an investigation into the event, affirming in a press declaration: "This epidemic is the first its size and range to be traced to an external entertainment event. Since the lifting of COVID-19 state prevention measures at the end of June. "

According to an internal presentation of disease control and prevention centers (CDC) recently obtained byThe Washington Post, theDelta variant is much more contagious That previous strains, more than other viruses such as the ebola virus or cold and cold cold for chickenpox and quotes in search that even vaccinated can broadcast the virus. But while many health officials have publicly encouraged theback of face masks inside For all peoples, regardless of vaccination status, the new debate to know if major outdoor events are a threat generating new responses from some experts.

"What we learn about this particular variant is that theViral loads are initially higher, so the exposure time is shorter, "Mercedes CarNethon, Vice-President of Preventive Medicine at the University of Northwestern School of Medicine, said CNBC do it.

Others point out that despite the contagious variant of the variant, all outdoor events are not also risky. "The clogged in the room, the more they will happen,"Jorge Parada, MD, Medical Director of Loyola Medicine Infection Control Program, CNBC said it.

Nevertheless, others warn that a combination of factors could createconditions that can propagate the varianteven outside. "There is a limit to how much air currents can dilute and disperse the virus, so if you have a congested outer environment, you can bypass this beneficial dilution effect"Charles Haas, PhD, Professor of Environmental Engineering at the University of Drexel, saidThe Philadelphia Investigator.

"Wear a mask and stay away if you can scream, sing and applaud," he added. But Haas always suggests getting your shots like the best form of protection overall, saying "If you are vaccinated, the risk and the consequences should be low in any event."

If you plan to attend an external event, the CDC recommends wearing an outside mask each time you can not be six feet From someone you do not live with. And according to Bromage Erin , PhD, Professor of Biology at the University of Massachusetts, Dartmouth, be sure to take precautions in any Overcrowded or covered areas arena or stadiums, especially in toilet lines or concessions. "I would like to hide going into these spaces," he told Boston CBS affiliated WBZ-TV.
