A new study out of a pediatric medical center in Chicago suggests that young children do not only spread COVID-19 more efficiently than adults, but they could be major drivers in the pandemic as schools start to reopen.The report was published at the end of July and examined concentrations of COVID-19 in the nasopharynx, or the upper region of the throat that connects nasal passages. According to the results, children ages 5 and younger who develop mild to moderate symptoms have 10 to 100 times as much COVID-19 in their nasopharynx as adults.“This is a very complex issue involving not just the virus, but everything else,” said Dr. Kwang Sik Kim, director of pediatric infectious disease at Johns Hopkins University Hospital. "We don’t have any real data to indicate to schools what they should do, what is the best recipe they need to follow.”The study raised concerns about the erratic behavior of children and how it could play a factor in the virus’ spread, reading, "Behavioral habits of young children and close quarters in school and daycare settings raise concern for SARS-CoV-2 amplification in this population as public health restrictions are eased. In addition to public health implications, this population will be important for targeting immunization efforts as SARS-CoV-2 vaccines become available.”“Don’t, under any circumstance, even think about opening that school for in-class instruction until you’ve got the virus under control,” said Lily Eskelsen Garcia, president of the National Education Association.Eskelsen Garcia teaches 39 6th-graders in Salt Lake City and says unless the infection rate of a community is below 5 percent, as outlined by the CDC and WHO, school districts should not even consider opening for in-person instruction.Currently, the infection rate in the United States is 7.8 percent."If you open a school before you get the infection rate under control, you will turn that school into the community’s super-spreader,” said Eskelsen Garcia.“Make a decision for today based on the information available today, and then act differently when you have data tomorrow. I think that’s the right approach,” said Dr. Kim. 2170

A new warning Tuesday cautions toxic chemicals were discovered in several popular back-to-school items. Everything from crayons and markers, to binders and water bottles.The U.S. Public Interest Research (USPIRG) groups tested 27 school supplies and found that some of them contained toxic chemicals like asbestos, lead, benzine and phthalates, which have been linked to cancer and other health hazards.“You can't assume that things are automatically safe when they're on our store shelves,” says Danny Katz, with USPIRG.Katz's team found Playskool crayon from Dollar Tree had trace amounts of asbestos. But that wasn't it.A blue jot band binder from Dollar Tree tested positive for phthalates.  Additionally, dry erase markers from Amazon tested positive for benzine, even though the packaging says nontoxic.“Just because a product says nontoxic like that, doesn't mean it's been tested for all the different chemicals,” Katz explains.Katz says what you should look for is a symbol, which confirms the product has been tested and approved by the Consumer Product Safety Commission.His team has put together a list for parents and teachers of products that tested positive for toxic chemicals and those that didn't.“There's just no reason that these chemicals need to be in the school supplies,” Katz says. “There's plenty of school supplies that don't have them. So we're shining a spotlight on which ones have these toxic chemicals which ones we didn't find in helping teachers and parents to stay safe.”  1535

A Northern California family was forced to evacuate their home over the weekend, as the Carr wildfire continues to spread. Not only was the family tasked with getting themselves out, they also had to evacuate the animals on their rescue farm.Lisa Ellsworth runs Tiny Tim’s Pals, a pet rescue farm in El Dorado Hills, California.“It’s our family, yeah,” says Ellsworth. "We take ‘em in from—sometimes they’ve been abandoned; a lot have been abused, neglected.”This weekend, those animals needed to be rescued from their sanctuary, as the fire in Northern California moved frighteningly close to their farm.“All the sudden, our neighbors come drivin’ up and they’re like, ‘Get out! We’re being evacuated,’” recalls Ellsworth. “The police are coming around, so that’s the notice.”Because of the time constraints to get out, they had to abandon two pigs and two feral dogs that couldn’t be corralled into trailers in time. The animals the family could take, they brought to the Rolling Hills Equestrian Center.Terry Skevington, with the center, says it’s one of the few places that allows owners to bring animals of all shapes and sizes. The animals can even sleep on site with them.“I had an old couple park here and stay with their cats, because the hotels wouldn’t let them stay with their cats,” says Skevington. “To some of ‘em, that’s all they got left.”He says the outpouring of donations of items--like fans for the animal stalls, halters and even feed--has been overwhelming.As for Ellsworth, she doesn’t know the status of her home or the animals she left behind, but she says she’s been able to keep it off her mind by staying busy. Fortunately, Ellsworth has insurance. She says in the worst-case scenario, she’d use the money as an opportunity to build a new barn for her animals.Representatives for the Humane Society that serves the region say, overall, they’ve seen about 1,000 animals displaced since the Carr fire broke out. About 150 of those animals have been housed at Rolling Hills. The center’s operators here say those animals and their owners can stay as long as they need.  2118

A pair of durable boots is a must-have in anyone's winter wardrobe -- and a team of archaeologists has found a timeless pair in a very unlikely place.The skeleton of a man, dating back around 500 years, has been discovered face down in the mud under London's River Thames, with his thigh-high leather footwear remaining virtually intact.The find was made in Bermondsey, south London, by archaeologist working on London's new "super sewer," a ￡4.2 billion (.4 billion) tunnel that will capture, store and transfer raw sewage and rainwater that currently overflows into the river. The mystery of the man's sturdy (and sought after) footwear has prompted the team to investigate further.Leather was an expensive commodity in Tudor times, and it is unlikely someone would be buried wearing such a highly prized item, according to MOLA Headland, the firm leading the project -- meaning the man's demise was likely premature.But the company notes that the banks of the Thames were a hazardous place in the late 15th and early 16th century, to which the skeleton has been dated.He may have been "a fisherman, a mudlark or perhaps a sailor," the archaeologists speculated."By studying the boots we've been able to gain a fascinating glimpse into the daily life of a man who lived as many as 500 years ago," said Beth Richardson, Finds Specialist at MOLA Headland."They have helped us to better understand how he may have made his living in hazardous and difficult conditions, but also how he may have died. It has been a privilege to be able to study something so rare and so personal," Richardson added.The boots were built with extra soles and stuffed with moss or a similar material to help them last in tough terrain, according to the firm's conservation experts.Investigation of the man's bones has also provided further clues to the mystery.He was likely to have died under the age of 35 and had deep groves in his teeth most likely caused "by a repetitive action, like passing rope between his teeth as a fisherman might," according to the company. 2057
