The White House is again rejecting calls for a national mask-wearing mandate.White House chief of staff Mark Meadows says in an appearance on “Fox and Friends” Monday morning that the president sees the issue as a “state-to-state” matter.He says that, “certainly a national mandate is not in order” and that “we’re allowing our local governors and our local mayors to weigh in on that.”New Jersey’s Democratic Gov. Phil Murphy has said he’d like to see a national strategy on the coronavirus, including a mask requirement. He says his state is seeing “small spikes in reinfection” from residents coming back from Florida, South Carolina and other virus hotspots, and the U.S. is “as strong as our weakest link right now.”Vice President Mike Pence has also rejected the idea of a national mandate, saying that’s up to governors and local health officials. 862

The U.S. reported yet another daily high mark for newly reported cases of COVID-19 on Thursday with nearly 188,000, according to a database kept by Johns Hopkins University.The U.S. reported at least 187,833 positive COVID-19 tests on Thursday, breaking the all-time record of 177,224 that was set six days prior, on Nov. 13.Thursday marked the eighth time in November that the U.S. broke the daily record for newly reported cases as the COVID-19 continues to spread across the country. About 2.5 million people in the U.S. have contracted the virus since the start of November.The spike in cases has led to all-time highs in hospitalizations linked to the virus. The COVID Tracking Project reports that more than 80,000 people are currently hospitalized with the virus across the country — an all-time record that surpasses even the early portions of the pandemic. According to the COVID Tracking Project, 71% of those hospitalizations occur in the Midwest and South, leading to many rural hospitals running short on resources. Some states like South Dakota and Iowa say their hospitals are at their breaking points.Thursday also saw reports of 2,000 deaths linked to the virus — the first time the U.S. has seen that many reported deaths in a single day since May 6. Since Oct. 17, daily deaths linked to COVID-19 on a seven-day rolling average have nearly doubled from about 700 a day to more than 1,300 a day. The continued spike comes amid a rash of promising news in the hope for a COVID-19 vaccine. On Friday, Pfizer announced that it had filed for Emergency Use Authorization for its vaccine candidate, two days after initial studies showed it to be 95% effective in large-scale trials. Several other drugmakers have also reported that their vaccines are on the precipice of authorization.However, health experts warn that the U.S. is in for a rough few months. Vaccines will initially need to be rationed for people in high-risk populations and health care workers. Dr. Anthony Fauci has said he believes vaccines won't be widely available until April. 2075

The White House privately warned the mayors of 11 major U.S. cities on Wednesday that they need to take "aggressive" steps to control COVID-19 outbreaks, the Center for Public Integrity reports.The warning came from Dr. Deborah Birx, the response coordinator for the White House Coronavirus Task Force. In the call, which the Center for Public Integrity included "hundreds of emergency managers and other state and local leaders," she identified 11 cities that are seeing an increase in the percentage of positive COVID-19 tests they've taken in recent weeks. Those cities were Baltimore, Cleveland, Columbus, Indianapolis, Las Vegas, Miami, Minneapolis, Nashville, New Orleans, Pittsburgh and St. Louis.“When you first see that increase in test positivity, that is when to start the mitigation efforts,” she said in a recording obtained by Public Integrity. “I know it may look small and you may say, ‘That only went from 5 to 5-and-a-half [percent], and we’re gonna wait and see what happens.’ If you wait another three or four or even five days, you’ll start to see a dramatic increase in cases.”The Center for Public Integrity also published a seven-minute segment of the conference call.Public Integrity · Dr. Deborah Birx CallIt's unclear who provided the Center for Public Integrity with the recording, which was closed to the press. The outlet also reported that it's unclear which local governments were on the call, which was hosted by the White House Office of Intergovernmental Affairs. Officials in Cleveland told the outlet that they were not on the call.Birx's call came the day after President Donald Trump resumed his daily coronavirus briefings. During those briefings, Trump encouraged the nations to wear a mask when in public — a significant shift after he refused to do so in public appearances earlier this year. But Trump also seemed to downplay the severity of the virus by claiming that mortality is falling, despite figures from Johns Hopkins that show mortality increasing. 2009

The three wildfires currently burning in California are moving across land with a terrifying speed.At its fastest, the Camp Fire in Northern California spread at more than a football field a second, or around 80 football fields per minute. It burned through 20,000 acres in less than 14 hours on Thursday. By Friday, it had reached 90,000 acres.PHOTOS: 3 wildfires rage in CaliforniaThe Woolsey Fire in Ventura and Los Angeles counties doubled in size in a 90-minute period Friday morning, to 8,000 acres -- by Friday evening, it was up to 35,000 acres.The Hill Fire in Ventura County torched 10,000 acres in six hours Thursday.Why are the fires moving so quickly?The combination of strong offshore winds that have been gusting as high as 70 mph, humidity values in the single digits and extremely dry conditions are leading to the perfect conditions for wildfires 872

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
