Health departments around the U.S. that are using contact tracers to contain coronavirus outbreaks are scrambling to bolster their ranks amid a surge of cases and resistance to cooperation from those infected or exposed. With too few trained contact tracers to handle soaring caseloads, one hard-hit Arizona county is relying on National Guard members to pitch in. In Louisiana, people who have tested positive typically wait more than two days to respond to health officials — giving the disease crucial time to spread. Contact tracing tracks people who test positive and anyone they’ve come in contact with. It was challenging even when stay-at-home orders were in place, but it’s exponentially more difficult now. 724

From birthdays to graduations to Sunday dinner, the COVID-19 pandemic has changed how families gather, especially when grandparents are involved."If you would have asked me as recently as six to nine months ago, if we would have ever considered buying or owning an RV, that would have probably been the furthest thing from my mind," said Chuck Boetsch.For Chuck and his wife, Robyn, travel has always been a priority both domestic and international. But back in 2017, Chuck had a left lung transplant after dealing with idiopathic pulmonary fibrosis for four years, leaving him immunocompromised."One of the things that, being at an advanced age is the desire when you have children and grandchildren is to have the ability to see them. So, being locked down since March, it’s been really difficult not being able to have the personal interaction with our children and grandchildren," said Chuck.Chuck and Robyn live in Tampa with one of their daughters, the other three live in Wisconsin, Illinois, and Colorado."FaceTime and technology are great but it’s no substitute for seeing people individually. So, after thinking about it for quite some time and how we could do it knowing that flying for both of us is out of the question, we decided to rent an RV," said Chuck.They liked it so much, they bought their own. They believe it's the only way to safely see family for at least the next few years. Not only do they not deal with other people at airports or on planes, but they’re staying in a much safer environment."So far, we’ve really kind of enjoyed it, it’s been fun," said Robyn.They say they’ve seen parts of the country they never knew were so breathtaking that they've always just flown over."I didn’t know it was so beautiful. Those states are just absolutely gorgeous," said Robyn.So far, they’ve taken a trip out west to visit family in Colorado. They just got back from a 12-day trip up north stopping to see two of their daughters and their families, even celebrating Robyn's birthday."It’s not without its problems, though. There’s a lot that goes into it in terms of planning, how much medication you take, how much food you take, how many miles can you effectively drive in one day, and where we’re going to stop," said Chuck.However, it’s all worth it when you get to spend time with your family."We miss our family. And that’s the only way we can see them," said Robyn. 2400

Hot weather can increase the risk of natural disasters like droughts and wildfires, now, there is evidence extreme heat can increase harmful chemicals in the air.A study published recently in Science Advances looked at asphalt under different temperature conditions.“A main finding is that asphalt-related products emit substantial and diverse mixtures of organic compounds into the air, with a strong dependence on temperature and other environmental conditions,” says Peeyush Khare, a Yale chemical and environmental engineer and the lead author of the study, in a statement.The researchers took real-world samples of fresh road asphalt and put them in a controlled furnace with purified air. They heated the samples to temperatures between 104 and 392 degrees Fahrenheit, and measured the chemical components in the air.Total emissions nearly doubled when temperatures went from 104 to 140 degrees. At 104 degrees, 94 percent of the emissions measured were hydrocarbons.The group also exposed the asphalt samples to replicated solar heat, including UVA and UVB wavelengths, and found the rate of emission of potentially harmful chemicals increased. Showing that not only heat, but also solar radiation contributed to asphalt producing air pollution.Paved surfaces and roofs make up approximately 45% and 20% of surfaces in U.S. cities, respectively.Asphalt can be quite a bit hotter than the air around it, getting about 40 to 60 degrees warmer than the recorded air temperature.The researchers concluded that while policies and regulations have been put in place about car emissions and other forms of air pollution, asphalt should not be overlooked as a contributor.“It's another important non-combustion source of emissions that contributes to SOA (secondary organic aerosol) production, among a class of sources that scientists in the field are actively working to constrain better,” Drew Gentner, associate professor of chemical & environmental engineering, said. 1983

HOOVER, Alabama — One week after Alabama police said they killed a mall shooting suspect -- then said he probably wasn't the shooter -- authorities say they've arrested the real assailant.Erron Brown, 20, was arrested Thursday at a relative's home in South Fulton, Georgia, US Marshals supervisor Frank Lempka said.Brown faces one count of attempted murder for the Thanksgiving night shooting at Riverchase Galleria Mall, an upscale shopping center in the Birmingham suburb of Hoover.Moments after the shooting, a Hoover police officer working security at the mall shot and killed a different man -- Emantic Bradford Jr. And over the past week, Hoover police kept changing their story about why he was shot.First, Hoover police said a 21-year-old suspect -- later identified as Bradford -- shot and wounded an 18-year-old man and a 12-year-old innocent bystander.Then police said Bradford probably didn't pull the trigger, but he did brandish a gun.Then they said Bradford had a gun in his hand, but didn't say that he was threatening anyone with it. (The Bradford family's attorney said the young man had a legal permit to carry a weapon.)All this has led to growing accusations of racial profiling and demands for answers. But the case has been turned over to the Alabama Law Enforcement Agency (ALEA), which said Wednesday that it will "not release information concerning pending criminal investigations."On Thursday, Hoover city officials held a news conference asking ALEA to release "limited information" on the case to the public. Council member Derrick Murphy noted that protesters had been demonstrating this week outside the mayor's home.City officials did not say what "limited information" they wanted the state to publicize. But Murphy said the city is asking the state to release that information by noon Monday."We have also discussed a follow-up plan in the event that we don't receive the information by Monday at noon," Murphy said. In that case, Murphy said, Hoover Police Chief Nicholas Derzis will decide "whether or not to release limited information on his own."When asked why city officials wouldn't take questions at Thursday's news conference, City Administrator Allan Rice says they wanted to wait until Bradford's funeral Saturday before releasing any information related to the investigation.Rice says he doesn't know what type of limited information might be released Monday.The Hoover officer who was working as security at the mall when he killed Bradford is on administrative leave, pending the outcome of the investigation.Meanwhile, the 18-year-old shooting victim, Brian Wilson, and the 12-year-old girl who was hit by a stray bullet are recovering from their injuries.Wilson's attorney, John C. Robbins, issued a statement offering condolences to the Bradford family -- and calling for more dialogue about police shooting deaths of black men."The Wilson family hopes that this tragic event will lead to real, open and honest dialogue not only between the African-American community and the police, but also the entire community must be involved in this discussion," Robbins wrote."Reckless police shootings of young black men must stop. But they will not end until there is rational and productive communication between the entire community and the police force, whose duty it is to protect that community."The-CNN-Wire 3364
