Two weeks after being grounded by the FAA, a Boeing 737 Max airplane en route from Orlando, Florida, to Victorville, California, had to return to Orlando International Airport to make an emergency landing Tuesday afternoon, the Associated Press reported. The jet, which was being shuttled to California for storage, only had two pilots on board. The jet belongs to Southwest Airlines, according to the AP.The Boeing 737 Max was grounded by US officials two weeks ago following the second deadly crash involving the series of planes. The AP reported that the emergency was not related to a glitch in the anti-stall software, which investigators believe caused the two previous planes to crash. On March 13, the FAA released a statement that said, "The grounding (of Boeing 737 Max planes) will remain in effect pending further investigation, including examination of information from the aircraft’s flight data recorders and cockpit voice recorders. An FAA team is in Ethiopia assisting the NTSB as parties to the investigation of the Flight 302 accident. The agency will continue to investigate." 1108

When it comes to vaccinating yourself — or your kids — against the flu, there are two options in the United States: a traditional shot or a nasal spray.Yet among children, the nasal spray appeared to have reduced effectiveness against the flu, compared with the shot, in past flu seasons, according to a study 323

Two rural town school districts in the United States were shut down early for the Thanksgiving holiday weekend due to a fast-spreading stomach virus causing an abnormally high number of absences.Mesa County Valley School District officials in Grand Junction, Colorado, closed the school district to decontaminate November 20, the Wednesday before the week of Thanksgiving. A high number of students were increasingly calling out sick due to an illness going around. “Before the school district shut down, we were aware of at least 13 schools within (Mesa County Valley) School District 51 that had increased absenteeism levels due to illness and that number was growing,” district officials said on a Facebook live video, addressing the problem. “What we’re suspecting at this time is it’s very much acting like a norovirus.”On November 25, Greater Albany Public Schools in Albany, Oregon, announced a district-wide closure for similar reasons — norovirus was going around causing high levels of absences.“It spreads really like wildfire through a community,” said Dr. Chris Nyquist, the medical director of infection prevention and control at Children’s Hospital Colorado. “I think norovirus is one of those viruses that comes up in wintertime often when you have small communities, thinking about schools, where a lot of kids are together. It’s very contagious, spreads quickly.”Norovirus symptoms include vomiting, diarrhea and nausea that can last days.“The best method that these schools have done, in conjunction with talking to their health department, is to really shut down and do extensive cleaning,” Nyquist said.Norovirus can transfer easily through close contact, and symptoms start as soon as two hours later. In small communities like Grand Junction or Albany, an outbreak like this can have a large impact.“The thing that’s really special and unique about rural Colorado is that schools are often time the hub of the community,” said Elaine Belansky, the executive director for the Center for Rural Health and Education at the University of Denver. “They don’t have that many boots on the ground to address big challenges like this.”But those communities are doing what they can to stop illness from spreading just as the holidays begin. Mesa County Valley School District posted a video of the decontamination process in one of their classrooms to Facebook to show the efforts being done.As for prevention, Nyquist said the best thing to do is to wash your hands with soap and water. 2512
