The spread of COVID-19 is tough to trace and even tougher to predict, but researchers at Pittsburgh’s Carnegie Mellon University created an early warning system to help protect you from the virusMathematics professor Po-Shen Loh developed an app called NOVID, a contact-tracing app, to help communities see the virus coming before they get infected.On top of creating a brand new app, Loh teaches math to middle-school students online from his own office-turned-broadcast studio. He’s also the national coach for the United States Math Olympiad team that competes around the world.But when the pandemic hit, Loh wanted to take on one more project. “I like things that are supposed to be impossible, that can’t be done,” said Loh. Stopping the spread of the coronavirus seemed to fit the bill.“The problem with COVID is it spreads before you know you have it, that’s what makes COVID different," Loh said. "The only way you can control this disease is in helping people to know whether or not COVID is coming close to them in advance."That’s where the NOVID app can help, said Loh. “Shows the virus coming towards you based on your relationship network, so that you can protect yourselves from others before you actually get infected," Loh explained of the app. "This is in contrast to most other contact tracing apps that are designed to protect others from you."The app shows you positive cases in degrees of separation. A positive case in the first degree would be someone you live with. The second degree could be your coworker or a friend. The third degree would be that person’s spouse or child. Each degree of separation is a possible pathway for you to come in contact with COVID-19.“This thing shows you the virus coming towards you, kind of like a hurricane satellite shows you a hurricane coming towards you,” said Loh.In addition to showing you cases as they pop up around you, the app can track the distance between phones down to the inch.It uses both Bluetooth and ultrasound waves to give you that measurement to make sure you’re safely social distancing.“We don’t know of any other contact-tracing app in the entire world which will tell you, ‘here’s how far away we think the device was,’” said Loh.The safety of your personal information is one of the most important features of this app. It collects data, while you stay completely anonymous.“Many people are distrustful of an app that does contact tracing,” said Loh. “We never ask for your phone number or email."Those who are positive can self-report their case in the app. Loh is also working with cities and counties to integrate NOVID into health departments across the country. He said the health departments would issue a ticket with a number to each person who tests positive for the virus.That person would enter the number into their NOVID app, anonymously reporting the positive case in the community.“If this thing actually caught on, you’d see in all the cities and towns, whether it’s rural or urban, whenever COVID starts to rise up, you’d start to see everyone take caution. Not because anyone forced them to, but because they saw this is what would be useful,” said Loh.To create the powerful community resource Loh is hoping for, he said more people need to know about the app.“Right now, we only respond when the intensive care units are full, and then it’s too late, and people die on the sidewalk. But, what we wish would happen, is that people could see it coming, and then, everyone starts to be careful at the right time. With more traction, we can save more lives,” he said.Loh is hoping he can not only help save lives but help bring back life as we knew it.“The goal of what we’re trying to do is to give people headlights to drive in the dark. Our app is not designed to let other people control you; our app is designed to help you control your life,” said Loh.For more information on NOVID or to download it, click HERE. 3928

The United Kingdom says it will be the first to conduct COVID-19 vaccine human challenge trials.It's different than other vaccine studies. People will be deliberately infected with the virus, which speeds up the research process.Pending approval, the process will start in January at a London hospital. It will require about 90 healthy young adults between the ages of 18 and 30.The group 1 Day Sooner has recruited from all over the world, including 3,000 Britons.“If the vaccine works, then ideally, people don't get infected and if people do, then they will be closely monitored and treated, but because these are young and healthy people taking part in the trial, I think, researchers feel comfortable doing so because the risks of death are on par with something like kidney donation for people who are young and healthy,” said Abie Rohrig with 1 Day Sooner.Before researchers test the vaccine, they'll do a characterization study. That's where volunteers are infected by getting a vaccine to determine the right amount of virus to give during the trial.Because of the risk, 1 Day Sooner is advocating for the entire process to be made public.Results could come in May. Even though that's likely after other COVID-19 vaccines are licensed, it's still important because we need billions of doses and because of the unique data human challenge trials provide.“Researchers can understand how the virus works in the human body. They can understand the biological markers of immunity. In fact, much of our understanding of other types of coronaviruses come from challenge studies that were conducted in the 1960s in Britain,” said Rohrig.Human challenge volunteers are paid and monitored for at least a year after. 1722

The US Centers for Disease Control and Prevention continues to warn against eating any romaine lettuce harvested from the central Coastal growing regions of Northern and Central California amid a multistate outbreak of E. coli illnesses linked to romaine lettuce. The agency also reported Thursday that nine additional people have been reported ill since November 26.Now, 52 people have been infected with E. coli in this outbreak, which was announced in October, according to the CDC.Illnesses have been reported in 15 states: California, Connecticut, Florida, Illinois, Louisiana, Massachusetts, Maryland, Michigan, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island and Wisconsin.Nineteen people have been hospitalized, including two who developed hemolytic uremic syndrome, a type of kidney failure. No deaths have been reported.Last month, the CDC and the US Food and Drug Administration updated their warning against eating or selling romaine lettuce products harvested in the California counties of Monterey, San Benito, San Luis Obispo, Santa Barbara, Santa Cruz and Ventura. 1110

The U.S. Army has announced previously-scheduled leadership changes at Fort Hood as well as an investigation into the chain-of-command actions surrounding the case of Spc. Vanessa Guillen.Gen. Michael X. Garrett, commanding general of U.S. Army Forces Command, is directing that Maj. Gen. John B. Richardson IV formally assume duties as deputy commanding general for operations of III Corps and acting senior commander of Fort Hood.The change will take effect on Sept. 2.Army officials say the change in leadership was previously-scheduled and will enable "continuity of command" as III Corps returns from its role leading the Combined Joint Task Force-Operation Inherent Resolve.Maj. Gen. Richardson previously served as FORSCOM's director of operations from 2019-20 and was selected in March 2020 by the Department of the Army to serve as the next DCG for III Corps.Maj. Gen. Scott Efflandt will continue to serve as the deputy commanding general for support and will remain at Fort Hood to assist with the reintegration of III Corps as they return from their mission supporting Operation Inherent Resolve.With Maj. Gen. Efflandt remaining at Fort Hood, the Army will announce the name of a new commander for the 1st Armored Division, which Efflandt had previously been designated to lead. That announcement is expected in the coming days.The Army also announced that Sen. Garrett will appoint Gen. John Murray, commanding general of Army Futures Command, and one of the Army’s most senior commanders, to lead an in-depth investigation into the chain-of-command actions related to Spc. Vanessa Guillen.There are currently several investigations underway at Fort Hood. The Army says those investigations are tasked with reviewing a wide range of topics and concerns. According to the Army, Gen. Murray will roll those efforts into a more complete and comprehensive investigation that will delve into all activities and levels of leadership.Murray’s investigation, which will be conducted under the provisions of Army Regulation 15-6, is separate from the Independent Review of Fort Hood, which began in August.Full release: This story was first reported by Sydney Isenberg at KXXV in Waco, Texas. 2228
