The Centers for Disease Control and Prevention is now publicly acknowledging people can be infected with the coronavirus through airborne transmission, especially in enclosed spaces with inadequate ventilation.The update embraces growing evidence and international research showing the coronavirus can linger in the air longer - for minutes and hours - and travel farther than six feet.The update comes two weeks after the official CDC website was updated to reflect this, only to be removed a few days later with the agency saying it was “posted in error” before it was fully reviewed.The draft language seemed to imply aerosol or airborne transmission was the main way the coronavirus spreads, and the CDC says that is not the case.“Infections occur mainly through exposure to respiratory droplets when a person is in close contact with someone who has COVID-19,” the CDC states.Their added section is titled “COVID-19 can sometimes be spread by airborne transmission,” and includes information about smaller particles lingering in the air after an infected person had left the space. "Some infections can be spread by exposure to virus in small droplets and particles that can linger in the air for minutes to hours," it reads.“There is evidence that under certain conditions, people with COVID-19 seem to have infected others who were more than 6 feet away. These transmissions occurred within enclosed spaces that had inadequate ventilation. Sometimes the infected person was breathing heavily, for example while singing or exercising,” the new section on the CDC’s website reads. “These transmissions occurred within enclosed spaces that had inadequate ventilation.”The World Health Organization changed their guidance in July and noted the prevalence of airborne transmission of coronavirus and particles lingering in the air. Hundreds of scientists encouraged the WHO to make the acknowledgement following research and studies. 1943

The CIA has determined that Saudi Crown Prince Mohammed bin Salman personally ordered the killing of journalist Jamal Khashoggi, despite the Saudi government's denials that the de facto ruler was involved, according to a Washington Post report.Citing people familiar with the matter, the Post reported Friday that the CIA reached its conclusion by examining several sources of intelligence. According to the Post, US officials have high confidence in the CIA's assessment.A spokesman for the CIA declined to comment to the Post. The Saudi government has denied bin Salman's involvement in Khashoggi's death.Fatimah Baeshen, a spokeswoman for the Saudi Embassy in Washington, told the newspaper that the claims in the CIA's "purported assessment are false.""We have and continue to hear various theories without seeing the primary basis for these speculations," she told the Post.Khashoggi, a former Saudi royal insider who became a critic of the country's government, went missing in October after he visited the Saudi consulate in Istanbul to obtain papers for his upcoming marriage. The Saudi government offered changing explanations for Khashoggi's disappearance.Included in the US intelligence analyzed by the CIA was a phone call the prince's brother Khalid bin Salman made to Khashoggi, encouraging the journalist to make the trip to the consulate to get the documents, according to the Post. Sources told the Post that Khalid made the call at his brother's command.Khalid denied the Post's reporting, saying on Twitter that he had never spoken to Khashoggi by phone."I never talked to him by phone and certainly never suggested he go to Turkey for any reason. I ask the US government to release any information regarding this claim," Khalid said.He said the last contact he'd had with Khashoggi was via text in October 2017.Baeshen told the Post that Khalid, who is the Saudi ambassador to the US, and Khashoggi never discussed "anything related to going to Turkey."The CIA also examined an audio recording from inside the Saudi consulate provided by Turkey and a phone call placed from inside the consulate after Khashoggi was killed, according to the Post.Maher Mutreb, an alleged member of the Saudi hit team and a security official for the crown prince, placed the phone call to a top aide for bin Salman informing the aide that the job had been done, people familiar with the call told the newspaper.According to the Post, the CIA also based its conclusion on its evaluation of bin Salman as a leader who is involved in minor matters.The CIA does not know the location of Khashoggi's remains, according to the Post.The Trump administration on Thursday?imposed penalties on 17 individuals over their alleged roles in the killing of Khashoggi. Khashoggi's assassination has created a crisis for the Trump administration and drawn attention to President Donald Trump's business ties to Saudi Arabia and the relationship between bin Salman and Trump's son-in-law and senior adviser, Jared Kushner.Earlier Thursday, the Saudi Public Prosecutor's Office said 11 people had been charged for their involvement in the death of Khashoggi, adding that five are facing capital punishment for being directly involved in "ordering and executing the crime."Khashoggi was killed following "a fight and a quarrel" at the Saudi consulate, the prosecutor's office claimed. Prosecutors said Khashoggi was tied up and injected with an overdose of a sedative that killed him. Then, according to prosecutors, his body was dismembered and removed from the consulate by five people. 3617

The CDC recommends that anyone who has been within six feet for 15 minutes of someone infected with the virus to quarantine for up to two weeks.Texas A&M athletics direct Ross Bjork said contact tracing was a significant factor in postponing its game against Tennessee this weekend.“The nature of away game travel (flights, meals, lodging, locker room, etc.) naturally leads to an increase in the number of student-athletes, coaches and staff who meet the criteria for mandatory quarantine based on contact tracing guidelines,” Bjork said in a statement. “We are asking everyone around our university community to stay vigilant and follow all of the safety protocols and best practices as we approach the end of the fall sports seasons.”Here are the games postponed or canceled this weekend:No. 1 Alabama vs LSUNo. 3 Ohio State vs MarylandNo. 5 Texas A&M vs TennesseeNo. 12 Georgia vs MissouriNo. 15 Coastal Carolina vs TroyNo. 24 Auburn vs Mississippi StateMemphis vs NavyAir Force vs WyomingUL-Monroe vs Arkansas StateGardner Webb vs CharlotteNorth Texas vs UABRice vs Louisiana TechPittsburgh vs Georgia TechCalifornia vs Arizona StateUtah vs UCLA 1988
