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 stock market continued a September slide Monday, with the Dow Jones Industrial Average falling about 800 points at one point. The S&P 500 sank 1.2%, though a last-hour recovery helped it more than halve its loss from earlier in the day.The Dow Jones Industrial Average fell 509.72, or 1.8%, to 27,147.70 after coming back from an earlier 942 point slide. The Nasdaq composite slipped 14.48, or 0.1%, to 10,778.80 after recovering from a 2.5% drop.Monday’s downward movement was seen across many sectors, and market watchers point to multiple reasons.Multiple media outlets are reporting about documents indicating major banks around the world potentially ignored red flags and allowed millions to be transferred by questionable companies or individuals. Stock prices for banks, including JP Morgan Chase, fell on Monday. Many are worried about a spike in coronavirus cases and potential new “waves” of the virus; the United Kingdom announced they are seeing a sharp increase in cases.The recent death of Supreme Court Justice Ruth Bader Ginsburg and subsequent announcement a replacement could come soon means congress will be focused on hearings and the nomination process, and potentially not focused on any federal coronavirus relief aid, according to Marketplace.org.Without federal relief, economic experts have warned of a longer recovery. The Federal Reserve last week said the future of the U.S. economy remained uncertain.Over the weekend, China announced a new regulatory body that could blacklist foreign companies that put China’s national security at risk. NPR says this group could target U.S. tech companies operating in China, like Apple, Cisco, and others.Monday’s slide comes after a few weeks of stock market losses. September is historically the worst month for stocks, according to the Associated Press.“The market has been poised to just pull back, take a breather,” said Quincy Krosby, chief market strategist at Prudential Financial. “Raising capital is prudent during a month that is known statistically, historically for being difficult for the market.” 2095

The Senate Judiciary Committee on Thursday approved legislation to protect the special counsel from being fired, a rare bipartisan step that sends a warning signal to President Donald Trump not to remove Robert Mueller.The legislation, which would give Mueller and other special counsels the ability to challenge their firings in court, still has little chance of becoming law — Senate Majority Leader Mitch McConnell has vowed not to put it on the floor, House Republicans have shown no interest in the measure and Trump would be unlikely to sign it.But the committee's 14-7 vote to approve the measure still provides a symbolic message that the Senate would not tolerate Mueller's firing. Four Republicans voted yes: Senate Judiciary Chairman Chuck Grassley of Iowa, Thom Tillis of North Carolina, Lindsey Graham of South Carolina and Jeff Flake of Arizona. 867

  

The Trump administration is taking steps to give telehealth a broader role under Medicare, with an executive order that serves as a call for Congress to make doctor visits via personal technology a permanent fixture of the program. The order President Donald Trump signed Monday applies to one segment of Medicare recipients — people living in rural communities. But administration officials say it’s intended as a signal to Congress that Trump is ready to sign more significant legislation that would permanently open up telehealth as an option for all people with Medicare. Trump says his administration is “taking action to make sure telehealth is here to stay.”"When the invisible enemy struck our shores, we took immediate action to eliminate regulatory barriers to telehealth, making it easier for patients to consult with doctors from safety and convenience and really, they have great safety and great convenience right from their homes," Trump said. While the CDC said in June it was working on expanding access to telehealth, it did list some drawbacks to the service:Situations in which in-person visits are more appropriate due to urgency, underlying health conditions, or inability to perform an adequate physical examThe need to address sensitive topics, especially if there is patient discomfort or concern for privacyLimited access to technological devices (e.g., smartphone, tablet, computer) needed for a telehealth visit or connectivity issuesLevel of comfort with technology for HCP and patientsCultural acceptance of conducting virtual visits in lieu of in-person visits by HCP and patientsInterstate licensure challenges and other regulatory issues that may vary by state 1701

  

The White House National Security Council is ending the role of cyber coordinator, according to an internal announcement obtained by CNN on Tuesday.The internal announcement said the elimination of the cyber role, just weeks into the tenure of national security adviser John Bolton, was part of an effort to "streamline authority for National Security Council Senior Directors."The announcement said the cyber coordinator job would end as Rob Joyce, the latest to hold the post, returned to the National Security Agency."With our two Senior Directors for Cybersecurity, cyber coordination is already a core capability," the announcement read. "Eliminating another layer of bureaucracy delivers greater 'decision, activity, secrecy and despatch (sic)' as Alexander Hamilton put it in Federalist Number 70."The elimination of the cyber coordinator job marked the latest of several changes to the National Security Council since President Donald Trump named Bolton his national security adviser.CNN reported last month Bolton pushed out Tom Bossert as homeland security adviser to make room for his own team, as several other officials left the National Security Council, including deputy national security adviser Nadia Schadlow and Joyce, who served as Bossert's deputy.Politico?first reported?on the elimination of the post.Asked about the position at a Senate Homeland Security Committee hearing on Tuesday, Department of Homeland Security Secretary Kirstjen Nielsen said she had not discussed the decision with Bolton."I have not had a conversation with Ambassador Bolton about that particular issue," Nielsen told Michigan Democratic Sen. Gary Peters.Nielsen said DHS has "strengthened all of our relationships with the silos" in government that Peters mentioned in his question, and said she is in regular contact with Bolton on cybersecurity, the previous statement notwithstanding."Since Ambassador Bolton has come onto the job, he and I speak regularly," she said, describing cybersecurity strategy work between herself and Bolton as "hand in glove."She added the cybersecurity strategy released by her department on Tuesday was done in "close coordination" with NSC.During his first year in office, then-President Barack Obama?announced he was establishing the role of cybersecurity coordinator and warned at the time the nation needed to bolster its online security efforts.Mississippi Rep. Bennie G. Thompson, the top Democrat on the House Homeland Security Committee, issued a statement responding to the news and accusing Bolton of "wreaking havoc" on the NSC."With cyber threats ever-changing and growing more sophisticated by the day, there is no logical reason to eliminate this senior position and reduce the already degraded level of cyber expertise at the White House," the statement read.Democratic Rep. Jim Langevin, of Rhode Island, said Tuesday he feels the decision was the "first major step backward" on cybersecurity by the Trump administration. He added the Trump administration had mostly followed in the footsteps of the Obama administration before this move."Bad move, big mistake, and just shows how out of touch and uninformed John Bolton is," Langevin said. 3227
