As mandatory face coverings become more and more common, keep in mind, some are better at protecting from viruses than others.When issuing their face covering guidelines, San Francisco specifically called out masks with one-way valves designed for “easier breathing”, warning that they allow for droplets to get out of the mask and potentially endanger others nearby. These valves are usually about the size of a coin on the side of the mask.The CDC, and many other health departments and officials, urge wearing a mask to prevent the spread of the coronavirus because it can be spread through respiratory droplets. Those droplets are produced into the air when an infected person coughs, sneezes, talks, sings, chants, shouts, etc. They can then land on other people nearby or be inhaled by others.The CDC recommends people wear a cloth face covering in public settings, to reduce the transmission of droplets into the air.“There are no high quality studies regarding the use of masks with additional types of various filters placed in them or with ‘breathing valves.’ While widely marketed with various claims, these have not been studied at all and it is unclear if they help or hurt the overall filtration efficacy against microorganisms,” read a statement from Marc Sala, M.D., Assistant Professor of medicine in the Division of Pulmonary and Critical Care at Northwestern University’s Feinberg School of Medicine.People are being asked to leave N95 masks (without a valve) and surgical masks available for medical staff and essential personnel who are coming into daily contact with many infected patients.An N95 mask with an exhalation valve is not recommended because unfiltered air is sent through the valve and into the air, potentially carrying coronavirus droplets. “The presence of an exhalation valve reduces exhalation resistance, which makes it easier to breathe (exhale). Some users feel that a respirator with an exhalation valve keeps the face cooler and reduces moisture build up inside the facepiece. However, respirators with exhalation valves should not be used in situations where a sterile field must be maintained…” according to the CDC’s website.Dr. Sala said testing has shown things like multiple layers of cotton fabric is better than a single layer, material of a higher thread count is more effective, and overall, “these studies emphasized the notion that if a mask doesn’t have a good fit (has gaps) its effectiveness is dramatically reduced.” Dr. Sala said even if the cloth mask is not ideal, it can still play a major role in preventing illness as more masks are worn by the population as a whole.Bottom line, choose a fabric face covering that fits and is comfortable around your ears or head, and keep it on while in public, especially when social distancing is not possible, to protect you and the people around you. 2864

An Australian labor union says it has fired two officials after investigating their links to a fake Black Lives Matter page on Facebook that attracted hundreds of thousands of followers, and took in money from donors.The National Union of Workers said in a statement Wednesday that it was "deeply distressed and appalled" by the revelations in a CNN report this week that linked one of the officials -- Ian Mackay -- to the fake Facebook page and other online black rights sites."The NUW has launched an investigation into claims made by a CNN report and has terminated the officials concerned," it added.A spokesperson for the union told CNN that it had "terminated" the job of Mackay -- a middle-aged white man -- and fired a second official, Ben Parker. Both held the title of "organizer" at the union, the spokesperson added.The union, which represents thousands of workers in various industries, "is not involved in and has not authorized any activities with reference to claims made in CNN's story," National Secretary Tim Kennedy said in the statement.CNN wasn't immediately able to reach Mackay or Parker for comment on Wednesday.The Facebook page, titled simply "Black Lives Matter," had almost 700,000 followers, more than twice as many as the official Black Lives Matter page.The scam page was tied to online fundraisers that brought in at least 0,000 that supposedly went to Black Lives Matter causes in the United States. At least some of the funds, however, were transferred to Australian bank accounts.Related: The biggest Black Lives Matter page on Facebook is fakeMackay denied running the Black Lives Matter page when CNN asked about his involvement last month. An anonymous Facebook profile under the name "BP Parker" was an administrator of that page until it was suspended, according to Facebook.Ben Parker -- the other now fired official -- declined to answer questions last week about CNN's investigation.Facebook suspended the fake Black Lives Matter page, but only after almost a week of exchanging emails and calls with CNN about the matter.CNN reported on Monday that the Black Lives Matter page consistently linked to websites tied to Mackay, who has registered dozens of domains, many on issues tied to black rights.In April 2015, he registered a site called blackpowerfist.com.Mackay's name, email address, phone number and other details appeared in the registration records for the site until July 2015, when the website enabled a feature that allows site owners to hide their identities and contact information.The Black Lives Matter Facebook page continually drove traffic to websites associated with blackpowerfist.com, which was eventually turned into a discussion forum.A few days after Mackay registered blackpowerfist.com, "BP Parker" shared a link to the website.The people behind the websites and the Facebook page encouraged people to donate through various online fundraising platforms.Related: Zuckerberg unscathed after five-hour Senate grilling sessionA source familiar with some of the payments processed said at least one of the accounts was tied to an Australian IP address and bank account. At least one fundraising account was tied to Ian Mackay by name, according to the source.Another source also familiar with some of the payments processed told CNN that the group had raised around 0,000 that they were aware of.The Black Lives Matter Global Network responded Tuesday to CNN's reporting. It said it was relieved that the fraudulent profiles had finally been taken down after repeated requests, and expressed hope that social media platforms would adopt protocols soon to prevent a repeat."We regret that so many people were deceived by the recent high profile scam into believing that their gifts and donations benefited us," it said in a statement.Mackay did not provide answers to multiple questions from CNN about his apparent links to the scheme, saying that "domain name buying and selling is a personal hobby.""I once bought the domain name only and sold it," he told CNN when asked about a Black Lives Matter website that was once registered to his name.Mackay declined multiple opportunities to clarify his role.-- Carly Walsh contributed reporting.The-CNN-Wire 4237

And they're married! Britain's Prince Harry and US actress Meghan Markle sealed their wedding vows with a kiss on the steps outside Windsor's St. George's Chapel on Saturday, cheered on by delighted crowds.The couple -- now the Duke and Duchess of Sussex -- then set off on a procession through the streets of Windsor in an open carriage drawn by four Windsor Grey horses.The bridal party, including three-year-old Princess Charlotte, Harry's niece, waved enthusiastically as the couple departed from the chapel after a ceremony that was unprecedented in British royal history.In a departure from tradition, Markle walked much of the way up the aisle unchaperoned, followed by her 10 bridesmaids and page boys -- a move that was seen as a powerful statement of her feminist principles.Rewatch the entire ceremony in the player below. It begins at about the two-hour mark:Her elegant white dress with an open bateau neckline was by British designer Clare Waight Keller, Givenchy's first female artistic director. Her 16-foot-long veil was held in place by a diamond bandeau tiara lent to her by the Queen.Only when she reached the 15th-century chapel's Quire was Markle accompanied for her final steps to the foot of the altar by Prince Charles, Harry's father.Harry, flanked by his brother and best man Prince William, looked emotional as he waited at the altar, dressed in the frockcoat uniform of the Blues and Royals.The couple sat with clasped hands as they listened to an impassioned sermon from Chicago-based bishop Michael Curry, the first African-American head of the Episcopal Church in the United States.His fiery preaching style was a marked departure from the usually conservative tone of a British royal wedding. Harry could be seen saying "Wow" to Meghan as the sermon ended.It was followed by a performance of the Ben E. King classic "Stand by me" by the Kingdom Choir, a group of 20 gospel singers.Meghan was all smiles as she said her vows and gave Harry his wedding ring. The crowd could be faintly heard cheering outside as the couple were proclaimed husband and wife by the Archbishop of Canterbury, Justin Welby, the most senior cleric in the Church of England.Big moments so far? Harry's aunt Lady Jane Fellowes, the sister of his late mother, Princess Diana, gave the reading from the Book of Solomon.? Palace revealed that Meghan's wedding ring has been made from Welsh gold and is a gift from the Queen, while Harry's is platinum.? The Queen conferred the titles of Duke of Sussex, Earl of Dumbarton and Baron Kilkeel on Prince Harry, making Meghan the first-ever Duchess of Sussex.The last to arrive before the bride was the Queen, wearing a lime silk dress, accompanied by Prince Philip.Among the host of famous guests already waiting in the chapel were Oprah Winfrey, George and Amal Clooney -- dressed in an eye-catching yellow dress and hat -- tennis star Serena Williams, actor Idris Elba and singer James Blunt.Former footballer and celebrity David Beckham stopped to hug a fan as he walked alongside wife Victoria Beckham, former Spice Girls singer turned fashion designer, toward the chapel door.Guests connected to the royal family included Pippa Middleton and her parents and Tom Parker Bowles, who is the son of Prince Charles' wife, Camilla. Earl Charles Spencer -- brother of Harry's mother, the late Princess Diana -- was another of the guests, as was Harry's aunt Sarah Ferguson, the ex-wife of Prince Andrew.Former Prime Minister John Major, who was made a guardian to William and Harry after Diana died in 1997, was another high profile guest. Current Prime Minister Theresa May was not invited.Senior members of the royal family, Prince Charles, the Princess Royal, Prince Andrew and his daughters, Princesses Eugenie and Beatrice were among the last to arrive.Crowds gathered in the streets of Windsor from early Saturday, hoping to catch a glimpse of the bride and groom as they process through the town in an open horse-drawn carriage following the ceremony. Other devoted royal fans have camped out for several days to get the best possible spot. Forecasters promise blue skies for the big day.Many more people planned to rise early (or stay up all night) in the United States to watch as Harry, long a favorite with the British public for his irreverent good humor, tied the knot with his California-born bride.The wedding represents a historic moment for the royal family, as it welcomes an outspoken biracial, American divorcée into its ranks.In a reflection of its contemporary nature, the couple chose a modern set of wedding vows, with the text of the formal parts of the service taken from Common Worship, the Church of England's standard liturgy, first published in 2000. It is thought to be the first time that this text has been used in a royal wedding.There was no promise by Markle to "obey" her husband. Rather, Meghan pledged to "love him, comfort him, honor and protect him." Harry has chosen to wear a wedding ring, unlike his brother.The award-winning young cellist Sheku Kanneh-Mason was chosen to play during the signing of the register. The ceremony will end with the Etta James version of "Amen/This Little Light of Mine," a gospel song that became synonymous with the US civil rights movement.The presence of Harry's mother was also felt at the ceremony. "Guide me o thou great redeemer" was sung at Diana's funeral, at her memorial service in 2007 and at Kate and William's wedding in 2011.Guests from Markle's side included cast members from "Suits" -- the legal drama in which she made her name. Actresses Abigail Spencer, Sarah Rafferty, Gina Torres and actor Gabriel Macht were all seen arriving.It appeared that TV legend and philanthropist Winfrey, dressed in Stella McCartney with a large hat, would be seated in the Quire with the family and other close friends, rather than in the main body of guests in the nave.In an effort to be inclusive, the couple invited 2,640 members of the public, including 1,200 ordinary people from communities around the United Kingdom, to watch from inside the castle grounds as the guests arrived.Among them were Helen McKenzie and Louis Davidson, who were invited through their local community in Somerset. "We got the invitation a while ago but had to keep it secret. It wasn't easy!" Davidson told CNN as the pair headed into the castle.Timeline: From blind date to 'I will'The-CNN-Wire 6409

An educational platform that was created to help the nation's teacher shortage is now helping schools backfill during the pandemic."Elevate K-12" offers live instruction, and some districts say it's filling in the gaps for students.Eighth-grade science looks a lot different these days, at least in Louisiana's Caddo Parish Public Schools."We really are almost the districts in one," Caddo Parish Public Schools Chief Academic Officer Keith Burton said.Of the district's 61 schools, 65% are Title 1 schools, meaning they receive federal funds for having large concentrations of low-income students.While the district also has magnet and gate programs, there were some instructional gaps."We really struggled in the area, as most districts do around the nation with needing enough mathematics teachers — especially around the middle and high school area — as well as science and foreign language teachers," Burton said.The district discovered Elevate K-12 two years ago and now use their live teachers for 67 periods."Anywhere from seventh-grade math to Spanish II, Algebra II, in about every corner of our district," Burton said."If you look at the entire U.S. K-12 population, there are 58 million students, of which 50.8 million are in the public school system," said Elevate K-12 CEO and founder Shaily Baranwal. "In that, about 22 million are low-income. The teacher shortage problem specifically plagues the low-income neighborhoods. We work with some states in some zip codes where they can't even find a grade four math teacher."Baranwal grew up in Mumbai, and Elevate K-12 was born out of a business school project."I'm that one Indian that rebelled and said I do not want to do engineering," Baranwal said. "I've always followed my heart, followed my passion. I'm an extreme non-conformist, so I did not follow that path and got an early childhood teaching certification. I then worked as a preschool teacher in India, came to the U.S. to Michigan to get my MBA."She says she created the platform to solve one problem: the nation's teacher shortage."One of the school districts we work with in Georgia — when I was talking to the head of talent there, they did not have an Algebra I teacher for the last four years," Baranwal said. "So, what they had to do was they took the local priest and made the local priest get an Algebra I secondary certification so the local priest could then teach the class."Elevate K-12 now helps large and small school districts around the country, and it just so happens to be in a unique position to help those who have gaps because of the COVID-19 pandemic."This solution was not created to solve a COVID problem," Baranwal said. "The teacher shortage problem has been plaguing the U.S. K112 schools and districts and specifically the low-income neighborhoods for years. What COVID has done for us is accelerated the entire acceptance of live streaming instruction as a solution."They have a network of more than 2,000 teachers, and more than 300 are actively teaching now. All are certified and based in the U.S."We are shaking up the K-12 antiquated system in making people realize that you should not offer a class like German or cybersecurity or science or math, just because you don't have a teacher," Baranwal said. "Take those barriers away and use live-streaming instruction so the teacher can be anywhere in the country. Your kids can be where they are and still learning in a highly engaging format."Burton says Caddo Public Schools hasn't had to use it for reasons related to the COVID-19 pandemic as of yet, but they're in a position to, should they need it.He added that the students adjusted quickly, and some even prefer personal and private teacher-student interaction."Now I'm able to leave those classrooms and see students engaged see students learning," Burton said. "Many times, students are saying I'm having conversations with a teacher in Colorado or North Carolina, and those students are loving it. They really are." 3992

An 11-year-old boy is now safe after getting sucked into a drain during Tuesday's flooding in Harrison, Wisc.. According to officials, the boy and some of his friends were playing in a retention pond that was completely full and draining at a high rate. Apparently, the boy got some goggles so he could see where the water was draining. He then got sucked in and disappeared under water. The boy's friends called 911 and emergency crews responded. Crews searched for 45 minutes until one of the rescuers saw the little boy sticking his finger through a manhole covering. The manhole lid was removed and the boy was pulled to safety. The boy was transported to a local hospital by Gold Cross Ambulance and was conscious and alert at the time.Sheriff’s officials are warning parents to not allow children to play in or near drainage ditches or retaining ponds especially during storms. The rapid water movement during these times can be life-threatening. 985
