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 email sent by a student to the principal and all of the freshmen at Oconomowoc High School prompted a police investigation into possible safety concerns.The email accused a different student of being a threat and mentioned the fictional character Slender Man.Police immediately investigated some of the claims in that email and the district says it determined there is no threat to student safety.The email sent on Wednesday includes many personal details about the student and says the person "...believes she has multiple personalities...is the daughter of slenderman."Slender Man became well-known in 2014, when two girls from Waukesha, Wisconsin — located about a half hour from Oconomowoc — said they stabbed their classmate 19 times to please the character.They both were recently committed to mental health facilities.In addition to mentioning Slender Man, the Oconomowoc student also claimed that this other student "wanted me to join her and two other girls in a cult-like group called the 'Trinity Sisters.'""I didn't find them to be true," said Alexis Zimmerman, a junior at the school.She says she and many other students weren't concerned about what the email said but were more upset that it even went out."I don't think anyone found it as a threat," she said. "It was just, it wasn't something right to say about someone else."Alexis' mother Nicole Gronitz says the school notified parents about the email, but she too wasn't concerned."It really didn't make me think twice about it," she said. "A lot of the stuff has just been kind of fake lately."District officials would not comment on any disciplinary issues. The full statement from the district is below: 1707

An Iowa couple and their two children died from inhaling toxic gas while vacationing in Mexico, local authorities said.The bodies of Kevin Wayne Sharp; his wife, Amy Marie Sharp; their son, Sterling, 12; and daughter Adrianna, 7, were discovered Friday at a rental condominium in the beach town of Tulum.The family had been dead for about 36 to 48 hours, the Quintana Roo prosecutor's office said Saturday. Autopsies showed they suffocated after inhaling toxic gases, but it's unclear what type of gas led to their deaths, the prosecutor's office added.There were no signs of foul play or suicide, officials said.Investigators ruled out a possible robbery because they did not see evidence of a disturbance inside the condo.Photos released by Mexican officials show crews and firefighters wearing masks while checking a gas stove in the condo.They performed "physical inspection of the room's gas installation" and are expected to release a technical report at a later date.Jana Weland, a relative, told CNN the family arrived in Tulum on March 15. They were staying in a rental house they found through a vacation rental company. The last contact the family had with the Sharps was a picture the son posted on Snapchat of his feet by the water that day, Weland said.The Sharps were supposed to return from their vacation Wednesday, Weland said. Kevin Sharp, who owns a beer distribution company, failed to check in with his employees that morning as planned, which was unlike him, Weland said.Then the family failed to attend a basketball game Wednesday night in Danville, Illinois -- a game Weland said the family was looking forward to. But the extended family waited until Thursday night to call authorities in case the Sharps had problems with their flight. 1770
