LA JOLLA, Calif. (KGTV)-- A new article shows that wearing masks is even more critical than previously thought. UC San Diego researchers compiled several global studies that looked into how the coronavirus spreads and found that masks can help stop the spread of many aerosol particles.The idea of wearing masks has become a polarized issue in America. But Dr. Kim Prather, a distinguished professor at the UCSD Scripps Institution of Oceanography, says the science is clear."Masks do filter things, and filtering does reduce the spread of disease. That we know," Dr. Prather said. She and her colleagues released a new article compiling the latest COVID-19 studies around the world. Sneezing and coughing release large spit particles up to 26 feet, so that is clearly a point of concern. But Dr. Prather says we also need to focus on the invisible aerosols that can float around for hours, from asymptomatic virus carriers. "They don't have a fever, they're not coughing, they're not sneezing," Dr. Prather said. "But when they're talking, they can produce thousands of aerosols out in their breath, and infect people for days."That is why she reiterates that wearing masks is imperative."You wear a mask not to protect yourself. You wear a mask because you're being thoughtful and protecting other people," Dr. Prather said. One of the studies compares COVID-19 numbers between Taiwan and New York, which share a similar population. While New York had more than 353,000 positive cases and 24,000 deaths by the time Dr. Prather's paper was published, Taiwan only saw around 440 cases and seven deaths. Dr. Prather attributes Taiwan's drastically low numbers, partly to the quickly enacted masking orders. "Taiwan never shut down. They just wore masks," Dr. Prather said. So what kind of facial masks are most efficient? Dr. Prather says one that fits your face properly would protect you the best. Tightly knit, multi-layered cloth masks are good to rewash and reuse. Bandanas can leave many gaps between the contours of your face, which is why it may not be as effective in blocking out particles. Whatever the style, Dr. Prather says that you see the mask moving up and down while breathing, it is a sign that it is working. The more we protect ourselves now, the quicker we can return to normal. "We can get back to a functioning society if we wear masks," Dr. Prather said. "Until tests come in to play or a vaccine comes into place, it'll buy us time, and we can reduce the spread if we take this seriously."Dr. Prather says that while masks do not block 100% of aerosol particles, it is much better to block some than none. 2638

LAS VEGAS (KGTV) -- Friends of a San Diego pilot killed in a Las Vegas plane crash in late October said he had years of experience.Friends identified the pilot as Robert Golo.The passenger, 35-year-old Tyrone Calabar, was also killed.“It was kind of a shock to everybody. We still can’t believe it,” said fellow pilot and Golo’s friend, Flynn Ortiz. “He was so well known and so well respected.”On the morning of October 29th, the plane crashed near Raven Avenue, several miles southwest of the Las Vegas strip. Witnesses told the Clark County Fire Department they saw the plane flying low before hearing the crash.The plane was supposed to be heading back to Gillespie Field.Ortiz said he and Golo’s planes were parked next to each other at Gillespie Field. “I’ve known him for a couple years. I’ve flown with him quite a bit,” Ortiz said.Ortiz said because of his charter license, Golo was under more scrutiny and underwent more inspections. “He owned the airplane that was involved in the accident, another twin-engine airplane, and a small jet. He was very well experienced.”According to Golo’s LinkedIn page, he had operated Air Charter Express since the late 1980s.Both the NTSB and the FAA are investigating. A preliminary report is set to be released in the upcoming days. The official cause of the accident likely will not come for at least a year, according to the NTSB. 1388

LA JOLLA, Calif., (KGTV)— San Diego beaches were bare this Memorial Day Weekend, and as overcast skies and sprinkles kept people from visiting the usual destination spots. May temperatures should be in the 70s, but highs in La Jolla only reached the low 60s.Mother nature dictated beachwear today at La Jolla Shores. Scarves, hoodies, even fluffy parka jackets were on full display."It is really cold," one woman said. "Whoever said it never rains in Southern California, that song, that was a lie," joked another man. The unofficial first weekend of summer in San Diego was much gloomier than expected. For the Gardner family, that meant a change in plans. "We brought the wetsuits out actually, in case it turned into a beach day, but it looks like it's not," Kelsey Gardner laughed. She and her husband Andrew had their boys, Miles and A.J. fly kites instead. 10News did meet a group of men who were excited to jump into the chilly waters. "I am pursuing diving, and here I am taking my certification. I am excited!" Navy sailor Griffin Leboffe said. He and fellow active duty sailor Brian Mims were heading into the waves with their scuba diving instructor, Harvey Forbes. Forbes said days like today are perfect diving weather. "Ambient temperature is colder when you get in, and that's just the way your body works. It actually feels warmer," Forbes said. Plus, low beach attendance meant more available parking, and better concentration during their certification test. "Here, there are a lot less people, and it's more spread out, so I feel like it would be easier to get out there," Leboffe said. But as the divers were heading in, most everyone else was heading out. During our interview with his parents, four-year-old A.J. began packing his sandals and kite. "I want to go home!" he said. "I don't like it when it rains!!" 1842
