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 Trump administration is considering a new travel ban to replace its original executive order, which has had its legality questioned and is up for a Supreme Court hearing next month, White House national security adviser H.R. McMaster said Sunday."Well, this is something that we're looking at, is how to protect the American people better, how to ensure that we know who these people are who are moving," McMaster told George Stephanopoulos on ABC's "This Week."This renewed discussion of the travel ban comes after Friday morning's terrorist attack in London, in which 30 passengers on a London Underground train were injured after a bomb went off.In a tweet Friday in response to the attack, President Donald Trump called for a "larger, tougher and more specific" travel ban and also called for shutting down terrorist group's use of the internet for indoctrination and recruitment.McMaster echoed the point Sunday."Because of the strength of these terrorist organizations -- why this is a greater danger than ever -- is, first of all, their ability to communicate, to connect what would otherwise be disconnected cells in other places in the world," he said. "The second part of this is their ability to travel and to move and to move people and money and weapons, oftentimes drugs and other illicit goods, internationally. So part of the strategy must be to interdict these networks, interdict them from how they use information, and communicate, but how they move physically, as well.The Supreme Court is set to hear?oral arguments in the travel ban case early next month.The President's executive order would suspend travel from six Muslim-majority countries (Iran, Libya, Somalia, Sudan, Syria and Yemen) for 90 days while the secretary of homeland security and others submit a report on the results of a worldwide review to identify what additional information will be needed from each country to make sure an individual seeking entrance is not a public-safety threat.Responding to a lawsuits from states challenging the ban, the Supreme Court let much of the ban take effect in late June, meaning the 90-day clock started and will hit on or around September 24.Administration officials have not divulged the specifics of their future plans.At a recent homeland security conference in Washington DC, acting Customs and Border Protection Deputy Commissioner Ronald Vitiello said, "We are in the process of action planning about each of the opportunities that the US government has to interview and/or vet potential inbound travelers."That could include "looking at things like social media, looking at things like smart phones, those kinds of windows, if you will, into people's backgrounds and their activity," he said.The-CNN-Wire 2771

The school buildings in Evanston, Illinois, are still empty. But the district’s recently hired superintendent caused a stir during a public Zoom meeting announcing how the they will decide which students get priority seating when in-person learning resumes.“We have to make sure that students, who have been oppressed, that we don’t continue to oppress them, and we give them opportunity,” said school superintendent Dr. Devon Horton of the Evanston/Skokie school district in late July.“We will be targeting our dependent learners – those are students who are marginalized first,” he said.Low-income students, special needs and those dealing with homelessness are just some who will be first in line. There have been angry letters, petitions and even death threats to the superintendent and school board.“Understanding that other folks are experiencing more vulnerability and more harm than my family is experiencing,” says Anya Tanyavutti, a parent of two and the Evanston district’s school board president. “I'm happy to see those resources go to people who need it more.”For the last four years, the Evanston school district has been working on implementing anti-racism resolutions and curricula to address inequity.“Taking an anti-racist stance requires some sort of sacrifice,” says Dr. Onnie Rogers a professor at Northwestern University’s school of Education and Social Policy. “I think that's really the part of racial equity that our country is still getting used to on the ground.”Here in Evanston, the achievement gap does fall along racial lines where Black and Latino students are one-third as likely as white students to meet college readiness benchmarks.The district acknowledges that its plan to allow some students to return before others falls mostly along racial lines. But it is need, they say, not race, that will be the determining factor.“If we simply said we're gonna just reopen for whoever wants to come, then the people who are most well-resourced and most well-connected would likely be able to get those seats prior to people who are challenged with homelessness or challenged with getting food on the table,” says Tanyavutti.And there has been opposition. Arlington, Virginia, based ‘Students for Fair Admissions’- a non-profit advocacy group that has mounted legal challenges to affirmative action, has called the district’s plan unconstitutional.“If that student has unique special needs then that's fine to take those into consideration,” says Edward Blum, president of Students for Fair Admissions. “What is not fine to take into consideration is the skin color or ethnic heritage of students.”“It has been legally reviewed, and I am confident that we are operating within the bounds of our Constitution,” says Tanyavutti.In-person learning is tentatively scheduled to resume in mid-November. And while the district says it will accommodate as many students as possible the priority remains their most vulnerable student population. 2974

The US Postal Service is asking for the biggest price jump on stamps in its history.Facing pressure from the Trump administration to address a revenue shortfall, the Postal Service on Wednesday proposed raising the price of 1-oz. letters from 50 cents to 55 cents, which would be a record nominal increase if approved. The price of each additional ounce would go down slightly.The request was made by the USPS' board of governors, which has been operating on an emergency basis?because of a lack of confirmed members. It will have to be approved by the Postal Regulatory Commission."The Governors believe these new rates will keep the Postal Service competitive while providing the agency with needed revenue," the USPS said in a press release. "The Postal Service has some of the lowest letter mail postage rates in the industrialized world and also continues to offer a great value in shipping."Rates for mailing services -- which includes catalogs and magazines as well as letters -- are pegged to consumer prices. Those have been rising faster this year, but still limited the price hike for that category to 2.5 percent.Prices for packages, however, can float with market rates. The USPS wants to boost Priority Mail prices by an average of 5.9%. A small flat-rate box that costs .20 to ship, for example, would next year cost .90.The steep price increases come at a time when the USPS' losses have been mounting, dragged down in part by a requirement that the quasi-public agency pre-fund the cost of retiree health benefits.As letters and advertising mailers have been replaced by e-mail and online ads, the USPS has been making less and less money. Revenue from first-class mail declined from .4 billion in fiscal year 2015 to .6 billion in 2017.Package revenues fueled by the rise in e-commerce have been a bright spot, bringing in .5 billion in 2017, up from billion in 2015. But it hasn't made much of a dent in the .7 billion net deficit that the Post Office has accumulated over the years.The White House has proposed privatizing the Post Office, a plan that postal unions protested in nationwide demonstrations on Monday.President Donald Trump has repeatedly criticized the terms of USPS' contract to deliver Amazon packages, the details of which are confidential. The Postal Service says it makes a profit through the arrangement."Why is the United States Post Office, which is losing many billions of dollars a year, while charging Amazon and others so little to deliver their packages, making Amazon richer and the Post Office dumber and poorer?" Trump tweeted last December. "Should be charging MUCH MORE!"In April, Trump ordered a review of the Postal Service's business model by a task force led by the Treasury Department. Postal Service spokesman Carl Walton says the review has been completed, but that the agency hasn't seen it yet."I think they're waiting until after the elections," Walton said. "We're waiting just like everybody else." 3041

The UK will expel 23 Russian diplomats from the country after concluding that the Russian state is responsible for the attempted murder of former Russian spy Sergei Skripal and his daughter Yulia in the English city of Salisbury.This will be the single biggest expulsion of Russian diplomats in over 30 years, Prime Minister Theresa May said Wednesday. The 23 concerned, who May said had been identified as undeclared intelligence agents, will have only one week to leave."For those who seek to do us harm, my message is simple. You are not welcome here," she said in a statement to the House of Commons following a meeting of Britain's National Security Council.The expulsion of diplomats will "fundamentally degrade" Russian intelligence capabilities in Britain for years, May said.The Skripals are critically ill in hospital after being exposed to the nerve agent, known as Novichok and developed in Russia, on March 4. Thirty-eight other people in Salisbury were seen by medics after the exposure. One, a police officer, remains hospitalized.May said Monday it was highly likely that Moscow was behind the poisoning. The Russian ambassador to the UK was summoned to the UK Foreign Office to explain whether the attack was directed by Russian authorities, or whether Moscow had lost control of the nerve agent.She demanded that Moscow respond by midnight Tuesday, London time, to the UK government's conclusion that Russia was linked to the poisoning of Sergei Skripal and his daughter Yulia on a park bench in Salisbury in southern England.But Moscow -- which has repeatedly dismissed any accusations of involvement in the attack -- ignored the deadline.  1672
