Researchers from Florida Atlantic University released a video on Tuesday that shows how droplets disperse into the air from a person’s mouth.The researchers used different kinds of masks to analyze the disbursement of the droplets. The researchers also showed that without a mask, six feet of distance might not be enough to avoid infection.The FAU team tested a single-layer bandana-style covering, a homemade mask that was stitched using two-layers of cotton quilting fabric consisting of 70 threads per inch, and a non-sterile cone-style mask that is available in most pharmacies. The team used a mannequin, Laser lights and synthetic fog to help visualize the spread of the droplet from a cough..The researchers said that stitched quilted cotton masks worked the best in the simulation, with droplets from emulated coughs traveling just 2.5 inches from the mask. By comparison, without a mask, the droplets moved more than 8 feet, with some droplets traveling up to 12 feet during a heavy cough. The researchers also noted that the droplets remained suspended in midair for up to three minutes in the simulated environment.“We found that although the unobstructed turbulent jets were observed to travel up to 12 feet, a large majority of the ejected droplets fell to the ground by this point,” said Dhanak. “Importantly, both the number and concentration of the droplets will decrease with increasing distance, which is the fundamental rationale behind social-distancing.”FAU said that droplets from a cough traveled 3 feet, 7 inches from a bandana; 1 foot, 3 inches from a folded handkerchief; and 8 inches from a cone-style mask.“Preliminary results from our experiment reveal that significant concentrations of small particles from a turbulent jet such as from a heavy cough/sneeze can linger in still air for more than one minute. It only took the particles a couple of seconds to travel 3 feet; in about 12 seconds it reached 6 feet and in about 41 seconds it reached around 9 feet,” said Siddhartha Verma, an assistant professor in FAU’s Department of Ocean and Mechanical Engineering.Last week, the University of Washington’s Institute for Health Metrics and Evaluation projected that 33,000 American lives would be saved between now and October 1 by near universal wearing of masks.Last month, a study in the Lancet found that the use of masks and respirators by those infected with the virus reduced the risk of spreading the infection by 85%. The authors analyzed data that showed that N95 respirators in healthcare settings were up to 96% effective. Other masks were found to be 77% effective.The CDC issued guidance in April to recommend mask wearing while in public, which has become a requirement to enter retail establishments in more than a dozen states.The CDC's guidance stressed several points: That wearing a face covering is not a substitute for social distancing, and that the public should not use medical or surgical masks. The recommendations suggest the public should use fabric or cloth that covers the mouth and nose.To view FAU's video, click here. Justin Boggs is a writer for the E.W. Scripps National Desk.

President Donald Trump's son Donald Trump Jr. has tested positive for the coronavirus, the Associated Press reported on Friday. The AP said that Trump Jr. tested positive this week and does not have any symptoms. He has been isolating after testing positive. Last month, President Trump, first lady Melania Trump, and Barron Trump tested positive for the virus. Their cases came amid a massive outbreak of coronavirus cases within the White House. 455

Prisons across the country have suddenly become ground zero for the coronavirus.In California’s oldest jail, San Quentin State Prison near San Francisco, the number of cases has ballooned from less than 100 to more than 1,000 in two weeks.Attorneys in the area say the outbreak came from a transfer of inmates from the California Institute for Men to San Quentin.In the closed system that is a prison, it can make social distancing a challenge as there is only so much space to house inmates, particularly at a distance.Prison reform advocates say to solve the problem correctional facilities nationwide have turned to solitary confinement."The reports that I’m getting back now is not ‘Hey they put me in solitary for COVID-19.’ It’s, ‘They’re keeping me in solitary because of COVID-19,’” said Johnny Perez.Perez was formerly incarcerated at Riker’s Island in New York City for an armed robbery he committed when he was 21. He served 13 years for the crime, 3 of which were spent in solitary confinement, he says.“[It gave me] thoughts of suicide, volatility in my emotions,” said Perez. “I still need to sleep with the door open at night.”Perez says the experience in solitary can be similar for most people he knows, and thinks it is a dangerous way to combat COVID-19.“[The corrections system] treating you like an animal for the rest of your life says more about our system than it does about our individuals,” he said. “It is creating and lowering this standard of what it means to be put in solitary that is so low that it reverses all the work that we’ve done so far.”Perez is the director of the U.S. Prisons Program for the National Religious Campaign Against Torture, a group that works closely with the ACLU to form Unlock the Box, a national advocacy group fighting to end solitary confinement. Unlock the Box estimates the number of people currently in solitary confinement in U.S. prisons is 300,000; a large jump from the 60,000 it says was in solitary confinement in February.“There is a perpetuation and it is a really terrible cycle,” said Jessica Sandoval, campaign strategist for Unlock the Box. “[Inmates] are not going to report that they feel bad if that’s what the prison is going to do anyway so it’s pretty dangerous.”In an emailed response the Federal Bureau of Prisons did not respond to questions about solitary confinement in response to COVID-19, but it did say other measures it was taking to reduce the spread of the virus in the prison system through universal distribution of PPE, limited visits to those incarcerated, and no inmate transfers between facilities.Sandoval says medical isolation is a better practice, which does not strip inmates of many of their privileges. She also advocates early release for inmates nearing the end of their sentences or in the process of seeking parole."I think there needs to be a reckoning among corrections leaders and governors to say we’re going to do what’s right,” said Sandoval. "We’re going to save lives."According to the National Institute of Corrections it costs ,000 to house someone in solitary confinement for a year, as opposed to ,000 to house someone in the general prison population for a year. 3201

"I have been in my room, it's going to be fine, but it was really bad for a couple of days."Kardashian described her symptoms, including vomiting, coughing, shaking, and hot and cold flashes."I suffer from migraines, but this was the craziest headache; I wouldn't say it was a migraine," Kardashian stated in a hoarse voice. "The coughing in my chest would burn, and my throat is still not fully recovered, clearly. Let me tell you, that s--- is real. But we're all going to get through this.
