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 search for a 12-year-old thought to be trapped in a Mexico City elementary school ended Thursday with the news that all students have been accounted for.But rescuers will continue their work, as signs suggest that someone may still be alive in the rubble, Angel Enrique Sarmiento, Mexico's sub-secretary of Navy, said Thursday.For days, Colegio Enrique Rebsamen was the site of a massive search and rescue operation offering a glimmer of hope in the chaotic aftermath of Tuesday's magnitude 7.1 quake. Reports of the missing 12-year-old riveted people across the country, who watched the rescue efforts unfold live on television. 656

The showdown over mail-in ballots is expected to heat up this week.Democrats are calling back Congress to vote on legislation to prevent the U.S. Postal Service from changing any of its operations. A House committee also called an emergency hearing for next week to address mail delays and concerns the White House is interfering.The USPS is removing hundreds of mail processing machines across the country and has warned 46 states that it may not be able to process all mail-in ballots in time to be counted for the election.“Are we going to force people to have to choose between their fundamental right to vote and their health?” asked Shaundra Scott with the South Carolina Democratic Party. “The American voters are going to be very frustrated that we may not know who the winner is until frankly December.”Political experts agree the presidential race, pandemic and mail-in voting will all lead to massive increases in voter turnout and probably a lot of contested results.Some states have streamlined mail-in and absentee voting for years. However, other states are rushing to change their voting process because of the pandemic.“When things like that happen, it doesn't inspire confidence. It leads to the fear that people who shouldn't be voting may potentially be voting or people that should vote are not going to get ballots because of a snafu,” said Matt Klink, a GOP strategist with Klink Campaigns.For example, New York changed the rules to make it easier to vote by mail ahead of the primary, and it provided pre-paid envelopes. But those envelopes were not postmarked, or they were returned late. And there were other issues like ballots that weren't signed. That led to one out of four mail-in ballots being disqualified.But voting by mail could close the gap on inequities.“Yes, there are rules and regulations that say your employer should give you two hours to be able to vote but if you’re working hourly and you’re working on a job that is shift based, even though voting is extremely important, taking away that two hours of pay from someone and them having to make that decision is huge,” said Scott.Some expert say Republicans fear mail-in ballots would capture new Democratic voters, but seniors also benefit from absentee and mail-in voting. They often skew red, according to the Brookings Institute.A major study of California, Utah, and Washington state's elections between 1996 and 2018 found there was no partisan advantage to voting by mail. 2482

The world's No. 1 tennis player’s offer to upgrade a tennis center in Boca Raton was rejected by the public park system’s leadership Monday, and many in the community call it a win. The Greater Boca Raton Beach and Park District had been looking to upgrade Patch Reef Park since 2014.Tennis star Rafael Nadal wanted a tennis academy in his name, which would have included restaurants, dorms, indoor and outdoors courts.The district has been looking at renovating the tennis center at Patch Reef Park since 2014. Last summer, Rafael Nadal had reached out and offered to help build a new indoor facility. "It just wasn’t right. It was wrong. We’re happy to have Nadal here but build elsewhere. This place belongs to the people of Boca Raton," said Dina La Voe, an advocate of Patch Reef Park. Instead, the park will make a request for proposals and have more public input. It’s possible for Nadal to win a bid that way.At the beginning of the month, renderings of the facility were shared and the facility was called the “Rafael Nadal Academy.” The renderings showed indoor and outdoor tennis courts, dormitories, and restaurants.District executive director Arthur Koski said the district was not going to agree to what the Nadal group had offered. “We advised the Nadal group that an academy would not be something we would consider.” “Right now, we think the best first step is a step backwards,” said Koski.Some people in Boca Raton were not happy to hear about the proposed Nadal Academy. “It looks to me like they are tearing everything out of here,” said Dan Bianco. Koski said he would like to see different ideas about an indoor tennis center that would fit everyone's needs.  1745

The Wisconsin Supreme Court said Thursday it will not hear President Donald Trump's lawsuit, which had been requested to overturn election results in two Wisconsin counties.The lawsuit sought to overturn 200,000 ballots in Wisconsin. The decision from the Supreme Court comes just days after the Wisconsin Election Commission officially declared Joe Biden as the winner of Wisconsin."What we had is an abuse of the absentee process, dramatically in Dane and Milwaukee County,” said Jim Troupis, attorney for the Trump campaign.The lawsuit specifically focused on absentee ballots that were cast both through the mail and in person.The suit aimed to dismiss absentee ballots where the clerks' offices "inserted missing information,” people cast ballots "claiming Indefinite Confinement status" even if they "no longer qualified,” and absentee ballots "improperly cast or received at ‘Democracy in the Park’ events,” which were held in Madison.Governor Tony Evers and the Wisconsin Election Commission have said the Trump Administration is required to file the lawsuit in circuit court, not the state Supreme Court.This story was originally published by Julia Marshall at WTMJ. 1183
