The top U.S. public health agency stirred confusion by posting — and then taking down — an apparent change in its position on how easily the coronavirus can spread from person to person through the air.But officials at the Centers for Disease Control and Prevention say their position has not really changed and that the post last week on the agency’s website was an error that has been taken down.It was “an honest mistake” that happened when a draft update was posted before going through a full editing and approval process, said Dr. Jay Butler, the CDC’s deputy director for infectious diseases.The post suggested that the agency believes the virus can hang in the air and spread over an extended distance. But the agency continues to believe larger and heavier droplets that come from coughing or sneezing are the primary means of transmission, Butler said.Most CDC guidance about social distancing is built around that idea, saying that about 6 feet is a safe buffer between people who are not wearing masks.In interviews, CDC officials have acknowledged growing evidence that the virus can sometimes be transmitted on even smaller, aerosolized particles or droplets that spread over a wider area. Certain case clusters have been tied to events in which the virus appeared to have spread through the air in, for example, a choir practice. But such incidents did not appear to be common.Public health experts urge people to wear masks, which can stop or reduce contact with both larger droplets and aerosolized particles.But for months, agency officials said little about aerosolized particles. So when the CDC quietly posted an update Friday that discussed the particles in more detail, the agency’s position appeared to have changed. The post said the virus can remain suspended in the air and drift more than 6 feet. It also emphasized the importance of indoor ventilation and seemed to describe the coronavirus as the kind of germ that can spread widely through the air.The post caused widespread discussion in public health circles because of its implications. It could mean, for example, that hospitals might have to place infected people in rooms that are specially designed to prevent air from flowing to other parts of the hospital.But the CDC is not advising any changes in how far people stay away from each other, how they are housed at hospitals or other measures, Butler said.The CDC has come under attack for past revisions of guidance during the pandemic, some of which were driven by political pressure by the Trump administration.Butler said there was no external political pressure behind the change in this instance. “This was an internal issue,. And we’re working hard to address it and make sure it doesn’t happen again,” he said.In a statement released Monday, the CDC said the revisions to the “How COVID-19 Spreads” page happened “without appropriate in-house technical review.”“We are reviewing our process and tightening criteria for review of all guidance and updates before they are posted to the CDC website,” the statement said.At least one expert said the episode could further chip away at public confidence in the CDC.“The consistent inconsistency in this administration’s guidance on COVID-19 has severely compromised the nation’s trust in our public health agencies,” said Dr. Howard Koh, a Harvard University public health professor who was a high-ranking official in the Department of Health and Human Services during the Obama administration.“To rectify the latest challenge, the CDC must acknowledge that growing scientific evidence indicates the importance of airborne transmission through aerosols, making mask wearing even more critical as we head into the difficult fall and winter season,” Koh said in a statement.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

The U.S. has now seen two straight weeks in which at least 100,000 people are confirmed to have contracted COVID-19 each day.On Monday, the U.S. reported 166,000 new cases of the virus, marking the 14th consecutive day with 100,000 or more new cases of the virus, according to a database kept by Johns Hopkins University.The last day new cases totaled less than 100,000 was on Nov. 2. Since then, about 1.9 million Americans have contracted the virus, the rolling 7-day average of hospitalizations across the country has increased from 50,000 to 65,000 and daily deaths on a rolling 7-day average have ticked up from 824 a day to 1,114 a day.That 14-day time span has also seen seven days in which record numbers of new cases were reported. The current record was set on Friday when 177,000 people in the U.S. were confirmed to have contracted COVID-19.The current spike in caseloads has led hospitals across the country to become inundated with patients, overwhelming resources. The COVID Tracking Project reports that most of those hospitalizations are occurring in the Midwest, where rural hospitals in places like Iowa and South Dakota are running short on bed space.The current standard was predicted in June by Dr. Anthony Fauci, the nation's highest-ranking infectious disease expert. During a Senate hearing, Fauci stunned lawmakers by predicting that the U.S. could reach a point where 100,000 people were being infected each day if "disturbing trends" continued.Fauci's comments in June came during a summer spike in cases which saw infection rates top out at about 77,000 new cases each day.The current spike in cases comes as drugmakers like Pfizer and Moderna have reported encouraging results in vaccine trial results. While both vaccine candidates are on track for Emergency Use Authorization by the end of 2020, the drug likely won't be widely available to the general public for several months — Fauci has predicted that a vaccine will be widely available in the U.S. by April. 2002

The restaurant industry has been reshaped in the past six months. We’ve seen more pivots to take-out and outdoor dining, but could we see a more drastic shift.New data from Bank of America shows sales at independent chains are still down about 15%."Right now, it is just sad. People are exhausting their personal savings. They are shutting their businesses and they just don’t know what to do,” said Andrew Rigie.Rigie is with the New York City Hospitality Alliance. In NYC alone, at least 1,289 restaurants have closed since March, according to the Office of New York Comptroller. Across the country, Yelp has gathered data from its platform that show that number is around 16,000.“It’s a really dire situation,” added Rigie.The situation is the direst for independent restaurants, because the same Bank of America study that showed sales still down 15% at mom and pop restaurants, shows chain restaurant sales are now up 2% higher than they were pre-pandemic.Industry experts believe a continuing trend of these numbers could reshape the industry.Chains restaurants are now in a better position to replace space occupied by folded restaurants or struggling ones, potentially shifting the flavor of the restaurant industry toward chain food.“I’m not knocking or saying there is anything bad about a chain, but we really want our beloved mom and pop businesses,” said Rigie. "We really need support from the federal, state and local governments to ensure these places are able to recover.”Legislation was presented to Congress in June, the Restaurants Act, to help struggling independent restaurants with grant money. However, there has been no vote on the bill or any signs it could pass.Without additional help, the latest estimate by the Independent Restaurant Coalition is that upwards of 85% of independent restaurants could fold by the end of the pandemic. 1870

The Salt Lake Tribune reported late Monday night that at least one person has died in a 'shots fired' incident on the University of Utah's campus. According to the university, it asked those on campus to "shelter in place" Monday night as authorities looked for the gunman, and other possible victims. Traffic was reportedly blocked off, and mass transit was shut down in the immediate vicinity of the shooting. The suspect is said to be 24-year-old Austin J. Boutain, who was wearing a coat, jeans and beanie, with a teardrop tattoo on his face. The university added that he may have been driving a forest green pick-up truck with Colorado plates.As of early Tuesday morning, he was still on the loose, and considered dangerous. 767
