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

As families along the Gulf Coast deal with the aftermath of Hurricane Laura, people in Iowa are still without power after a derecho with winds of up to 140 miles per hour hit parts of the state on August 10.The term derecho was derived in the state to characterize a line of fast-moving thunderstorms that can produce hurricane-force straight-line winds.“It’s just a mess,” said Steve Becker who farms 800 acres of corn and soybean crops just west of Cedar Rapids.The storm began in the western part of the state and roared to the east, damaging between 10 million and 14 million acres of farmland in the state.In Cedar Rapids, apartment buildings sit without rooves and cars lay totaled. The city was the hardest hit in the state as the National Weather Service measured wind speeds equivalent to that of a Category 4 hurricane.As you drive into Cedar Rapids, however, you see the most widespread damage as once tall-standing corn now bends at 45-degree angles or is completely flattened.“We had a good crop coming. We really did,” said Becker. “I mean, the biggest worry of everybody out there is how we get through this stuff. What are we going to do?”Shortly after the storm passed through, President Donald Trump surveyed the damage. Iowa’s Farm Bureau estimates around 6 million acres, or 40% of Iowa’s corn crops alone, were damaged. It has asked the governor to make a billion request for disaster assistance from the federal government.“This will have a dramatic emotional effect on a lot of producers, a lot of farmers,” said Craig Hill, president of Iowa’s Farm Bureau.Many farmers work on credit. They can spend millions of dollars on equipment such as grain bins, combines, and tractors, to name only a few. They then can spend hundreds of thousands of dollars on supplies for that year’s harvest, all relying on the money they earn to help pay off the debt and set themselves up for success the following year.Some corn is salvageable, but it will not weigh the same or produce the same quality, meaning farmers might make back a quarter of what they expected.Iowa accounts for around 20% of the nation’s corn supply. Considering its importance to livestock, meat and ethanol, the market effects could be far-reaching.“It’s going to be very difficult for us to get the work done on a timely basis and then the frustration of everything being slowed,” said Hill of the impending harvest set to begin at the end of September.“It’s just the way it is. Nothing you can do,” added Becker. 2508
