As students return to school and employees head back to the office all with new safety protocols likely including wearing a mask, a new study from Duke University explores which masks are more effective.Spoiler alert: A fitted N95 mask, usually reserved for those in the medical community, performed the best in their test. However, since many Americans do not have access to those and have been using a mix of store-bought or homemade cotton and fabric facial coverings, Duke tested 13 other kinds of masks.The study, which was published Friday, was prompted when a professor at Duke’s School of Medicine was asked to assist a local group buying masks in bulk for the community. According to CNN, the professor wanted to make sure the masks they bought were effective.Researchers gathered 14 kinds of masks, including the professionally-fitted N95 mask, a bandana, homemade cotton varieties, and a surgical mask. They then used a dark room, laser beam and cell phone camera to record how many droplets (which reflect the laser beam light) each mask allows through.For each mask test and the non-mask wearing control test, the speaker was recorded saying “Stay healthy, people” five times. Each mask was tested ten times. 1229

As school districts across the country prepare to send kids back to school in-person, many bus drivers are voicing concerns about the potential for COVID-19 to spread on school buses, where oftentimes social distancing is nearly impossible.For the better part of 32 years, Cheryl Merritt has driven a school bus in Hanover, Massachusetts. She has driven in every kind of weather condition imaginable, but this is the first year she’ll be driving a bus during a pandemic.“I just want all the kids on the bus to stay safe and the drivers to stay safe. If we have a driver who gets sick, they’re going to be out for at least 14 days,” she lamented, as she turned her bus onto a side street in a residential New England town.Merritt’s concerns are shared by school bus drivers and districts across the country. Many school bus drivers have retired from other professions, meaning their age makes them more susceptible to catching the virus.“I don’t want this, I don’t. I’m not ready to die,” the 61-year-old Merritt said.School buses are presenting a particularly difficult challenge as districts try to send kids back to the classroom. When fully loaded with kids, most school buses fit about 77 students. Cramming students into a bus though would be a perfect place for COVID-19 to spread, so many states are advising bus companies to have only one student per bench. But taking some bus capacity down to about 12 kids means school districts would need to run double or triple the number of trips each day just to pick every child up.Transportation experts say adding more buses would be nearly impossible given a nationwide bus driver shortage, which existed long before the outbreak.“It doesn’t matter what you’re gonna do with kids once you get them to school, you have to get them there first,” explained David Strong, who works with the School Transportation Association of Massachusetts.Strong’s other concern is that kids won’t adhere to social distancing guidelines or mask-wearing requirements once they get onto a bus.“There’s almost no way to realistically social distance on a bus,” he added.To address concerns about the spread of COVID, many school districts are mandating that school buses keep their windows open year-round to help with the flow of air. Some districts are also adding bus monitors to ensure kids, especially elementary school students, are following new guidelines.As for Merritt, she sees herself and other bus drivers as the first line of defense when it comes to keeping COVID-19 out of the classroom.“When you stop to pick up a child look at them, make sure they don’t look sickly or they’re coughing,” she said. 2655

ATLANTA, Ga. – The Centers for Disease Control and Prevention (CDC) announced Thursday that it has expanded its list of people who are at an increased risk of getting severely ill from COVID-19.While everyone is at risk of contracting the novel coronavirus, some people are more likely than others to become severely ill, meaning they may require hospitalization, intensive care or a ventilator to help them breathe, or they may even die.Older adults and people with underlying medical conditions remain at increased risk for severe illness, but now the CDC has further defined age- and condition-related risks.Before, the CDC said those 65 and older were at an increased risk of severe illness. Now, the CDC says it has removed the specific age threshold from the older adult classification. The agency now warns that among adults, risk increases steadily as you age, and it’s not just those over the age of 65 who are at increased risk for severe illness.The CDC says age is an independent risk factor for severe illness, but risk in older adults is also in part related to the increased likelihood that older adults also have underlying medical conditions.The CDC has also updated its list of underlying medical conditions that increase risk of severe illness. After reviewing reports, studies and various other data sources, the CDC found there is consistent evidence these specific conditions increase a person’s risk of severe COVID-19 illness:· Chronic kidney disease· COPD (chronic obstructive pulmonary disease)· Obesity (BMI of 30 or higher)· Immunocompromised state (weakened immune system) from solid organ transplant· Serious heart conditions, such as heart failure, coronary artery disease, or cardiomyopathies· Sickle cell disease· Type 2 diabetesThe CDC says these changes increase the number of people who fall into higher risk groups. An estimated 60% of American adults have at least one chronic medical condition and obesity is one of the most common underlying conditions that increases one’s risk for severe illness – with about 40% of U.S. adults considered obese.The more underlying medical conditions people have, the higher their risk.The CDC also clarified the list of other conditions that “might” increase a person’s risk of severe illness, including additions such as asthma, high blood pressure, neurologic conditions such as dementia, cerebrovascular disease such as stroke, and pregnancy.A report published Thursday further adds to the growing body of research on the risk for pregnant women. Researchers found pregnant women were significantly more likely to be hospitalized, admitted to the intensive care unit, and receive mechanical ventilation than non-pregnant women. However, pregnant women were not at greater risk for death from COVID-19.“Understanding who is most at risk for severe illness helps people make the best decisions for themselves, their families, and their communities,” said CDC Director Robert Redfield MD. “While we are all at risk for COVID-19, we need to be aware of who is susceptible to severe complications so that we take appropriate measures to protect their health and well-being.”Protecting yourself, your family, and your communityThe CDC says every activity that involves contact with others has some degree of risk right now. Knowing if you are at increased risk for severe illness and understanding the risks associated with different activities of daily living can help you make informed decisions about which activities to resume and what level of risk you will accept. This information is especially critical as communities begin to reopen.Officials recommend that everyone do their part to implement prevention strategies, such as focusing on activities where social distancing can be maintained, washing your hands frequently, limiting contact with and disinfecting commonly touched surfaces or shared items, and wearing a cloth face covering when you are around people you do not live with, especially when it is difficult to stay 6 feet apart or when people are indoors."By taking these steps, you can help protect yourself, your loved ones, and others around you, including those most vulnerable to severe illness," the CDC writes. 4219

ATLANTA, Ga. – The U.S. Marshals Service says it found 39 missing children in Georgia this month during an investigation called “Operation Not Forgotten.”The two-week operation in Atlanta and Macon resulted in the rescue of 26 children, the safe location of 13 kids and the arrest of nine “criminal associates,” the USMS announced Thursday.Additionally, investigators say they cleared 26 arrest warrants and filed additional charges for alleged crimes related to sex trafficking, parental kidnapping, registered sex offender violations, drugs and weapons possession, and custodial interference.The USMS says the missing children were considered to be some of the most at-risk and challenging recovery cases in the area, based on indications of high-risk factors such as victimization of child sex trafficking, child exploitation, sexual abuse, physical abuse, and medical or mental health conditions.Since its partnership with the National Center for Missing and Exploited Children, the USMS says it has recovered more than 1,800 missing children.“When we track down fugitives, it’s a good feeling to know that we're putting the bad guy behind bars. But that sense of accomplishment is nothing compared to finding a missing child," said Darby Kirby, Chief of the Missing Child Unit. “It's hard to put into words what we feel when we rescue a missing child, but I can tell you that this operation has impacted every single one of us out here. We are working to protect them and get them the help they need.”This month’s operation was the culmination of several months of planning and coordination between the USMS, NCMEC, Georgia Bureau of Investigation, Georgia Office of the Attorney General, Georgia Department of Family and Children Services, Georgia Department of Juvenile Justice, the Federal Bureau of Investigation and Children’s Healthcare of Atlanta.“The U.S. Marshals Service is fully committed to assisting federal, state, and local agencies with locating and recovering endangered missing children, in addition to their primary fugitive apprehension mission,” said Director of the Marshals Service Donald Washington. “The message to missing children and their families is that we will never stop looking for you.” 2233

Australian researchers have developed new technology that allows them for the first time to film a deep-sea swimming sea cucumber.For the time being, they're calling the creature a "Headless Chicken Monster." The name sounds like something a child would name their imaginary friend, but it's pretty accurate once you take a look at the headless blob. The strange sea cucumber was discovered using an underwater camera system in the Southern Ocean off the coast of East Antarctica. The high-tech camera is normally used for commercial long-line fishing, but in this situation, it worked quite nicely."We needed something that could be thrown from the side of a boat, and would continue operating reliably under extreme pressure in the pitch black for long periods of time," said Australian Antarctic Division program leader Dr. Dirk Welsford. "The cameras are providing important information about areas of sea floor that can withstand this type of fishing, and sensitive areas that should be avoided."The large area off the coast of East Antarctica, which is covered with cold-water corals and penguin foraging grounds, has been the focus of a bid to create a protection area — known as the Antarctic Conservation Zone.Now, researchers are hoping that the new technology that captured the rare footage can help the creation of that area.The proposal for protection has previously been endorsed by the commission's scientific committee three times, but China and Russia have blocked the proposal each year, according to a report in Naturer. 1592
