In updated guidance, the CDC said that those who have recovered from the coronavirus do not need to be re-tested for the virus for three months after their infection barring they’re asymptotic.The refreshed guidance suggests that the CDC expects those with previous coronavirus infections are unable to spread the virus for three months.“People who have tested positive for COVID-19 do not need to quarantine or get tested again for up to 3 months as long as they do not develop symptoms again,” the guidance says. “People who develop symptoms again within 3 months of their first bout of COVID-19 may need to be tested again if there is no other cause identified for their symptoms.”In a statement to CNN, the CDC clarified that does not automatically mean someone is immune for three months. The updated guidance comes after much discussion and speculation on the possibility of becoming infected for a second time with the virus.The guidance is “based on the latest science about COVID-19 showing that people can continue to test positive for up to 3 months after diagnosis and not be infectious to others,” the statement read. 1138

It’s been four months since most of the nation’s schools abruptly shut down because of the COVID-19 pandemic. Now, schools are considering reopening, while COVID-19 cases continue to rise. So what’s changed that supposedly makes a return to campus safe?“Occasionally you have schools close because there's an outbreak of measles or flu or something like that, but not to this scale,” Dr. Elizabeth Hinde, Dean of the School of Education at Metropolitan State University of Denver, said.Districts are scrambling to figure out how to return to school this fall as COVID-19 continues to spread across the U.S.Back in March, almost every school was forced to close, a mindset much different than today's.So what has changed? We sat down with a global health affairs professor, an education expert, and an infectious disease doctor to look at the changes between now and four months ago.Within the span of a week, states told their schools to shut down.“When everything closed down in March, we were comforting a new disease, we were terrified at what it could do,” Dr. Sandy Johnson, director of the global health affairs program at the University of Denver, said.Little was known about COVID-19.“School closures are always a part of the mitigation strategy along with quarantine, stay at home orders, etcetera,” Dr. John Hammer, an infectious disease specialist at Rose Medical Center, said. “The difference between March and now is that we have a better sense of how the virus works. How it’s transmitted.”There’s more to this decision than a better understanding of the virus.“When we’re talking about whether or not schools should open, another factor is the loss in achievement and also there are equity issues that have really come to the fore” Dr. Hinde said.Kids finished the school year from home -- some didn't have the proper tools or the support of a school, opening the door for inequity.“We know that there are mental health issues,” Dr. Johnson said. “Our front line social workers that are looking for domestic violence and we know domestic violence has been going up. So there are many important roles in addition to education that come in those schools.” This also includes food and housing insecurity.Another factor in consideration -- teacher health.“These folks are balancing fear. Fear for their health, fear for the health of their families, with this real desire. They understand how important education is,” Dr. Johnson said.“There's just no definitive answers that principals and superintendents and teachers can lean on,” Dr. Hinde said.What was a state decision in the spring has now been put on the shoulders of school districts, as they weigh the pros and cons of returning to in-person learning.“Every school board, every school district, has to make a very tough decision. It is a very delicate balancing act,” Dr. Hammer said.“Local control is a strength in American schools, but it does make decision making very complex, because the superintendents of schools and principals are listening to all these different voices,” Dr. Hinde said.From teacher health and safety, to inequities in learning and the mental health of children, school leaders have a lot of elements to look at when it comes to opening classroom doors.“I think in the next couple weeks we’ll see decisions made,” Dr. Hinde said. “All of this, it’s a new world.” 3367

It's official: The NBA is coming back on Dec. 22.The NBA and the National Basketball Players Association have struck a deal on rules for this coming season, setting the stage for what will be a frenzied few weeks before games resume. Teams will play a 72-game schedule, with the league announcing the full regular-season and broadcast schedules at a later date.The league said a new system would be used to ensure that the split of basketball-related income continues, one of the many details that had to be collectively bargained with the union because the current agreement between the sides had a great deal of language needed reworking because of the coronavirus pandemic.Teams will be able to negotiate with free agents beginning at 6 p.m. ET on Nov. 20, and at 12:01 p.m. ET on Nov. 22, teams will be able to sign them, the league announced in a press release.The league said the salary cap and tax level would remain the same heading into the new season. During the 2019-20 season, the cap was 9.14 million, with the tax level at 2,627,000."A new system will be used to ensure the parties' agreed-upon split of basketball-related income (BRI)," the league said in the news release. "In the event, player compensation were to exceed the players' designated share in any season, necessary salary reductions beyond the standard 10 percent escrow would be spread across that season and potentially the following two seasons, subject to a maximum salary reduction in any season of 20 percent."This season, teams will not be playing in a bubble, so health and safety protocols amid the coronavirus pandemic will need to be worked out as teams will be traveling from city to city once again.Last season ended on Oct. 10, so the Los Angeles Lakers and the Miami Heat will only have rested seven weeks before they start training camp on Dec. 1. 1856

  

It's been said that America is more divided now than ever before.The country currently finds itself in two camps with little hope of bridging the ideological gap. Both sides seemingly have the same set of facts but have come to two completely different conclusions — the consequences of the post-truth world.2018: The year of "alternative facts," where "truth isn't truth."And all of this chaos seemingly stems from one person with a Twitter account: @rebeccareilly__, or "becky."On Aug. 24, becky sent a tweet that would eventually garner more than 20,000 retweets and 34,000 likes as of Aug. 31. The tweet asked a simple question and had a single photo attached."Is this a door or a beach??? Hahahaha????" she wrote.  757
