The window to get COVID-19 under control is closing. That's the warning from the head of the Department of Health and Human Services.Secretary Alex Azar denies that reopening too quickly was tied to the recent rise in cases, blaming it instead on inappropriate individual behavior."If we don't social distance, if we don't use face coverings in settings where we can't social distance, if we don't practice appropriate social hygiene, we're going to see spread of disease,” said Azar.However, in Texas, the governor says if he could go back and redo anything, it would be to slow down the reopening of bars. In that state, the number of new cases has jumped from an average of 2,000 to more than 5,000 a day.Hospitalizations are rising at an alarming rate with some nearing capacity."Please understand these patients are very sick,” said Dr. Joseph Varon, Chief Medical Officer at the United Memorial Medical Center. “There are patients that are about to die. So, we have to admit them. Once they are here despite everything that we do, I mean they have to stay in the hospital anywhere from 5 to 10 days at a minimum. So those beds will be occupied for a period of 5 to 10 days so sooner or later within the next two weeks we are going to be at full house."Azar says the U.S. is actually better positioned now to handle the pandemic. He pointed to increased testing, contact tracing and greater reserves of personal protective equipment. 1446

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 separation of church and state has come under much scrutiny during this election season.At Zion Baptist Church in Denver, Pastor Rev. Frank Davis is encouraging members of his congregation to vote with faith.“My faith is voting what the bible says about right and wrong, about what the bible about a good neighbor,” he said.While leading a prayer service, Rev. Davis addressed issues ranging from race and religion to prophecies and politics.“America cannot be great with the division that it shares,” he said.A recent survey by the PEW Research Center shows nearly two-thirds of Americans want religious institutions to stay out of politics.Some churches, however, are still getting involved.During this presidential election, members of Zion Baptist Church are stepping outside of their house of worship and helping voters on the ground level.“As a faith-based entity, as a Christian entity, we believe that we are guided by principals that are really higher than day-to-day politics,” said Gwendolyn Mami, one of many members of Zion Baptist Church volunteering their time during this election by providing voters free rides to polling sitesVolunteers are also picking up and delivering ballots to those unable to do so for themselves.It’s a different kind of church service and comes at a time when there are questions nationally about both voter fraud and voter suppression.“This is a very strange time in which we are living,” Mami said. “There is a lot of confusion there is a lot of misinformation.”While Zion Baptist has a long history of political and social involvement in their community, Rev. Davis does not try to sway voters to match his own political views“I have never stood at this pulpit and given anyone a persuasion,” he said. “I will not do so even in this crucial election.”It's an election Rev. Davis says will impact America for eternity. 1875

  

The sudden and abrupt breakdown of the US Postal Service has unfolded in recent days as Democrats call for a funding boost ahead of this year’s presidential election.On Friday, the USPS announced a temporary price increase in some services from Oct. 18 until Dec. 27. The rate hike affects commercial services, as retail services are not affected.Meanwhile, the USPS has been removing mailboxes and processing machines. The machines and mailboxes are being removed across the country, according to local reports from a number of Scripps stations.On Friday, CNN and the Washington Post reported that a number of states have received letters from the Postal Service warning that they might not have the ability to ensure ballots are sent and returned in a timely manner. The warning comes as more Americans are expected to utilize mail-in voting due to the coronavirus pandemic.“The Postal Service is asking election officials and voters to realistically consider how the mail works,” Martha Johnson, a spokeswoman for the USPS, said in a statement to the Washington Post.Despite requesting a mail-in ballot himself for next week’s Florida primary, President Donald Trump has tried to sow doubt in recent weeks over the reliability of mail-in voting, claiming that the process is ripe with fraud. But there has been limited evidence to suggest his fears are founded.With the postal service facing financial troubles due to rising pension costs and decreasing usage, Trump said he would agree to funding the Postal Service, but would need some concessions from Democrats."Sure, if they gave us what we want. And it’s not what I want, it’s what the American people want," Trump said Friday. 1694

  

The Transportation Security Administration says they found three times the rate of loaded guns at checkpoints in July than they did at the exact time last year, despite fewer passengers traveling due to the coronavirus pandemic.In a press release, the agency said that 80% of the firearms that come through a checkpoint are loaded. "It’s just an accident waiting to happen," TSA Administrator David Pekoske said in the release.TSA said they found 15.3 guns per million people screened last month, which is up from the rate of 5.1 guns per million people in July 2019.The agency says that's alarming because they screened 75% fewer travelers last month.“TSA is diligently working to ensure our employees and passengers are safe and secure while traveling during a pandemic, and yet we are noticing a significant increase in loaded firearms coming into checkpoints,” said Pekoske in the press release. “Travelers must understand that firearms are prohibited items at airports and in the passenger cabins of aircraft. As hard as we are working to mitigate other risks at this time, no one should be introducing new ones.”Guns are permitted in checked bags, but they must be unloaded, and in a locked case, TSA said.Last year, 4,432 guns were found in carry-on bags at checkpoints nationwide, which is about 12.1 firearms per day, and 87% of them were loaded, the agency said. 1380
