The Florida Highway Patrol said 30-to-40 vehicles have flat tires Monday morning on Interstate 95 northbound from Lantana Road to the Okeechobee Boulevard exit in West Palm Beach. The vehicles have flat tires due to metal debris in the road from a semi.All of the vehicles are off to the side of the interstate.Scripps station WPTV in West Palm Beach flew over the area and did not spot any lane closures, but traffic is traveling slow in the area.Drivers should avoid using I-95 northbound in this area until all of the debris is cleaned up.  596

The divisive presidential election found students at Westminster High School in Maryland split over a controversial poster that some saw as a symbol of hope. Others viewed it as a knock on Donald Trump. But other symbols like the Confederate flag also sparked unrest at the school."Actually, we had a bunch of people having flags connected to their trucks.  People wearing it all the time,” said Jakob Hill, a 2017 graduate, “It was actually surprising to see it, but it was in the schools. I have a bunch of friends that are still in Westminster and they still see it."But starting today, they won't see it anymore.Superintendent of Schools Stephen Guthrie says both the rebel flag and the Nazi swastika are now banned anywhere on school property."While we were getting complaints from students who were not only offended. It goes much deeper than offense,” Guthrie said. “They really were losing the ability to do their work. This represented hatred to them. They thought it advocated violence. So we went through a process with our attorneys and legally to determine if we could make decisions that would limit that dress."Guthrie points to the move to remove Confederate statues from public lands and the rally that turned deadly in Virginia as evidence the change was needed."We have the Charlottesville issue with the swastika and the Confederate battle flag were side by side with acts of violence and hatred and intolerance, and so we saw this change happening around us," Guthrie said.It is a bid to prevent symbols of hate that can lead to violence."You never know who you're going to offend and it's just safe if you try not to wear them," Melanie Morel of Westminster said.Violence has already erupted among students inside the schools when symbols divide them."We had a couple of fights last year about it actually,” said Hill, “People using racist terms and all that and people taking it under a different context."The superintendent says when students violate the dress code his hope is to make it a teachable moment, rather than a punitive one, in hopes of bringing students closer together. 2160

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 FDA issued an emergency use authorization for a saliva-based coronavirus test that has been used to identify COVID-19 cases by NBA players. Leading officials are calling the test a “game-changer.”The SalivaDirect test is said to be both rapid in its findings, and inexpensive. Yale said it doesn’t hope to commercialize the test, rather increase the country’s testing capabilities.“Widespread testing is critical for our control efforts. We simplified the test so that it only costs a couple of dollars for reagents, and we expect that labs will only charge about per sample. If cheap alternatives like SalivaDirect can be implemented across the country, we may finally get a handle on this pandemic, even before a vaccine,” said Nathan Grubaugh, a scientist with Yale Public Health.Yale scientists say that the nasal samples are less invasive than swabbing, but are equally as accurate.“This is a huge step forward to make testing more accessible,” said Chantal Vogels, a Yale postdoctoral fellow. “This started off as an idea in our lab soon after we found saliva to be a promising sample type of the detection of SARS-CoV-2, and now it has the potential to be used on a large scale to help protect public health. We are delighted to make this contribution to the fight against coronavirus.”The test earned praise from members of the White House coronavirus task force.“The SalivaDirect test for rapid detection of SARS-CoV-2 is yet another testing innovation game-changer that will reduce the demand for scarce testing resources,” said Assistant Secretary for Health and COVID-19 Testing Coordinator Admiral Brett P. Giroir, M.D. “Our current national expansion of COVID-19 testing is only possible because of FDA’s technical expertise and reduction of regulatory barriers, coupled with the private sector’s ability to innovate and their high motivation to answer complex challenges posed by this pandemic.” 1926
