The coronavirus has had a significant impact on sports, and now football is beginning to see the virus affect the sport.NFL Network reports that the league and players’ union agreed to not hold a preseason this fall, which would have gotten underway next month. Given football’s schedule, the games provide teams with revenue as they’re generally included in season ticket packages. The decision comes with the likelihood of teams playing in front of no or a limited number of fans during the regular season. Several states have said that large gatherings will be limited into the fall.NFL Network added the league will expand training camp rosters, and there will be an opt-out for players at a “high risk” of having coronavirus complications. 752

The Centers for Disease Control and Prevention issued new guidance that recent studies have indicated that cloth masks offer more protection against the coronavirus than previously thought.Previous guidance suggested that masks were best used for preventing the spread of the virus. The CDC now believes that masks are effective for both stopping the spread and reception of the virus. The CDC said on Tuesday that multi-layer cloth masks can both block up to 50 to 70% of fine droplets and particles and limit the forward spread of those that are not captured. Overall, cloth masks offer up to 80% blockage in human experiments. The CDC’s analysis found that cloth masks offer comparable protection as surgical masks.“Studies demonstrate that cloth mask materials can also reduce wearers’ exposure to infectious droplets through filtration, including filtration of fine droplets and particles less than 10 microns,” the CDC’s guidance said. “The relative filtration effectiveness of various masks has varied widely across studies, in large part due to variation in experimental design and particle sizes analyzed. Multiple layers of cloth with higher thread counts have demonstrated superior performance compared to single layers of cloth with lower thread counts, in some cases filtering nearly 50% of fine particles less than 1 micron.”The guidance says that mandatory mask wearing can help prevent the need to implement economic shutdowns.“Adopting universal masking policies can help avert future lockdowns, especially if combined with other non-pharmaceutical interventions such as social distancing, hand hygiene, and adequate ventilation,” the CDC said.In an interview with Andrea Mitchell of MSNBC, Dr. Anthony Fauci said that wearing masks is “two-way street.”"Recent data has now shown that as a matter of fact, there's also the added benefit to protect you from droplets and virus that's coming your way," Fauci said Tuesday on MSNBC."“You protect others," he added. "Their masks protect you. And your mask also protects you."In a separate interview on Tuesday, Fauci said that shut downs can be avoided.“We are not talking about shutting down,” Fauci told CNN’s Jake Tapper. “There is always that misunderstanding when we talk about public health measures. We are not talking about shutting down. We are talking about the four or five things I talk about all the time, wearing mask universally, keeping a distance, avoiding congregate settings indoors over outdoors and washing your hands.”Editor's note: A previous version of this story said "masks were best used for spreading the virus" when it should have said "masks were best used for preventing the spread of the virus." That has since been corrected. 2729

The Federal Aviation Administration has issued a safety alert about flying with dry ice onboard, in anticipation of the huge nationwide distribution project anticipated to start in the next few days once the Pfizer COVID-19 vaccine is approved for use.The Pfizer and Moderna vaccines both need to be kept at extremely cold temperatures, requiring the use of dry ice during transit.Dry ice is frozen carbon dioxide that is pressed into blocks or pellets. It doesn’t melt into a liquid, it moves directly from a solid to a gas and that process can happen quickly at high altitudes.That can cause problems onboard a plane, such as causing the plane to weigh less at times during the flight and change its center of gravity.“CO2 sensors installed or carried in the aircraft or worn by the pilots and other crewmembers will assist the operator and crew in recognizing hazardous concentrations of CO2 and implementing effective risk controls,” the FAA’s safety alert recommends.In addition, they encourage maximum ventilation onboard while on the ground and in the air, asking crewmembers to check air conditioning units and auxiliary power units before flight.Exposure to elevated levels of CO2 can cause drowsiness or dizziness, and higher levels can impact breathing eventually leading to hypoxia and death.The FAA also recommends that “pilot training on specific conditions and procedures can improve pilot decision-making in the event of a CO2 detector alert or other system abnormalities.”Friday morning, Health and Human Services Director Alex Azar said Americans could begin getting the COVID-19 vaccine next week once the FDA and CDC give it emergency use approval. 1676

The country is heading into a COVID-19 winter without fully deploying widespread testing of sewage for traces of coronavirus, a Newsy investigation has found.Wastewater surveillance is one of the few proven tools able to track community spread of the disease, with the potential to help monitor immunity rates from new vaccines."It is frustrating," said David Larsen, an associate professor of public health at Syracuse University's Falk College. "We're going to see a huge amount of sadness over the next few months. And it's not too late to scale up wastewater surveillance at this time to help us with that."Early on, scientists realized infected people shed the virus in stool.The federal government began a big effort for analyzing the concentration of the virus in community wastewater."It's something I think from a national level we need to pursue," Assistant Secretary for Health ADM Dr. Brett Giroir said during a July webinar.Months later, the government has left it to state and local authorities to launch their own programs.For some, that's been a challenge.Newsy learned New York State, for example, suspended its sewage surveillance pilot after a month in part because of an equipment shortage.As a result, testing stopped in four places including Albany and Erie County, home of Buffalo.The University of Buffalo helped lead the project."UB is in the process of acquiring enough materials to continue the monitoring effort moving forward," university spokesman Cory Nealon said in an emailed statement.As with PPE, there is a global shortage of supplies needed to test sewage for COVID.Other places are struggling with how to pay for sewage analysis, with coronavirus aid from Washington running dry."The biggest factor, the limiting factor, is finances," Larsen said.The result is a patchwork of places examining wastewater across the country, mainly big cities and college campuses."It's not really a unified strategy, unfortunately," said Colleen Naughton, an assistant professor of civil and environmental engineering at the University of California Merced.She and her team plot testing sites on a map."When you zoom out of course the bubbles are big, so it looks like all U.S. is covered," Naughton said. "But when you zoom in you see it's a bit more spread out."Three states, Iowa, Rhode Island and South Dakota, don't have any surveillance sites at all, she said.Biobot Analytics looks for COVID in wastewater for about 200 cities and counties but has the capacity to do much more, said company president and cofounder Newsha Ghaeli."We're at the beginning, let's say that," Ghaeli said. "There hasn't really been a strong coming together yet around a specific approach or even standards."The CDC is still putting together a national wastewater surveillance system, building out a database not available to the public yet."It is, I think, valuable for the public to see that data and take action as a deciding factor for what activities and what risks am I going to take?" Naughton said. 3019

The four former police officers who were involved in an arrest that led to the death of George Floyd will asked a judge Friday that their cases be tried separately.In a hearing scheduled on Friday local time in Minneapolis, attorneys for Derek Chauvin, J. Alexander Kueng, Thomas Lane and Tou Thao asked Judge Peter Cahill that it will be "impossible" to evaluate each individuals' actions "in a vacuum," according to the Associated Press.According to the Minneapolis Star-Tribune, prosecutors opposed the requests, noting that witnesses and Floyd's family members are likely to be "traumatized" by multiple trials. They also argued that the "interests of justice" necessitate a single trial."Here, all four Defendants worked together to murder Floyd: Chauvin, Kueng, and Lane pinned Floyd face-down, while Thao stopped the crowd from intervening, enabling the other Defendants to maintain their positions. Defendants also discussed and coordinated their actions throughout the incident," prosecutors wrote in a court filing, according to The Associated Press.The Associated Press also reports that the request by the defendants indicates that the officers will seek to blame each other for Floyd's death. Attorneys for Lane and Kueng have already claimed that because their clients were rookies at the time, they were following the lead of Chauvin.The Star-Tribune also reports that the officers' attorneys sought a change of venue for the trial. Among their concerns about holding the trial in Minneapolis is a "tainted" jury pool.Judge Cahill took all of the defense's requests under advisement, according to ABC News. He did grant their request that four attorneys for the prosecution be dismissed from the case.Cahill said Hennepin County Attorney Mike Freeman and the three other attorneys should be dismissed from the case because they discussed autopsy results with the medical examiner, according to ABC.Defense attorneys have also filed a motion to dismiss the case, but the Star-Tribune reports that the judge is unlikely to discuss that motion Friday.Chauvin has been charged with second-degree unintentional murder, third-degree murder and second-degree manslaughter. The other three officers are charged with aiding and abetting murder and manslaughter.A trial date has been set for March 2021.Floyd died as officers attempted to arrest him for allegedly using counterfeit bills to buy tobacco on Memorial Day weekend. Bystander video showed Chavin kneeling on Floyd's neck for more than eight minutes as Floyd cried for help. All four officers were fired in the days following Floyd's death.Floyd's death sparked a massive wave of protests against police brutality and systemic racism across the country. 2727
