SAN DIEGO (KGTV) - New technology is offering schools another weapon in the battle against vaping and e-cigarettes.At this week's National Conference on Education, Soter Technologies is promoting its FlySense machine. It's similar to a smoke detector but tuned to sense vaping byproducts in the air."We can determine if a flavor is in the air, if THC is in the air, or if nicotine is in the air," says CEO Derek Peterson. "The device can determine what's in the air, whether someone's using a jewel pen, vaping, or an old fashioned e-cigarette, or a regular cigarette."The device then sends an alert to cell phones of nearby teachers and administrators so they can respond. Peterson says they've already sold 7,000 FlySense devices around the country, including 1,000 in California.It's helping schools fight a growing epidemic. A recent study in the Journal of American Medicine says 5.3 million teenagers admit to using e-cigarettes. The CDC says they're harmful to kids and adults and can be addictive."Kids get hooked on the vaping pens because of the nicotine content," says Peterson. "They think it's cool. And then before you know it, they're trapped. They're hooked on the nicotine. They can't get off."In addition to the FlySense machine, Peterson's company gives schools an educational curriculum to teach the dangers of nicotine and vaping. Because the machines have no cameras or recording equipment, Peterson says many schools install the devices in bathrooms and locker rooms, areas where cameras aren't allowed, and teachers can't monitor.For more information, go to www.sotertechnologies.com. 1616

SAN DIEGO (KGTV) — Nearly three-quarters of the students in San Diego County are currently learning from home, and those numbers don’t make a lot of sense to MIT professor Martin Bazant.Bazant is one of the creators of the COVID-19 Indoor Safety Guideline. The free online tool simulates the fluid dynamics of respiratory droplets in various kinds of rooms to show users the risk of different indoor environments.“If you run the numbers for a typical classroom, especially if the students and the teachers are wearing masks, then the amount of time in the room can be very significant,” Bazant said. “Essentially those people could spend a week in the classroom and not have a problem.”Bazant says the six-foot rule that has largely determined which businesses can stay open is overly simplistic. In some cases, he says the rule creates a false sense of security. In other situations, he says it causes the closure of businesses or schools that could safely operate.“If you place nursing home beds six feet apart in a shared room, they are absolutely not safe,” he said. But he said well-ventilated classrooms, with teachers and students in masks, are another story.“It's only the United States where we follow the six-foot rule. That's given by the CDC. The World Health Organization all along has been saying one meter, which is about three feet. If you simply followed the one-meter rule, all our schools would be open, as they are in most of the world right now,” he said.Bazant and his colleague John Bush said they set out to design a tool that would reveal the risk of transmission based on science, not guesswork.Users start by selecting a room type, like a classroom or an airplane. From there, they can control a wide array of variables to dial in the risk, like the room size, the ceiling height, and the ventilation and filtration systems.From there, users can further tune the model by human behavior. How many people are in the room? Are they whispering, shouting or singing? How many are wearing masks?Mask usage is a critical component, Bazant says. The model quickly reveals the challenges of maskless activities in rooms with poor ventilation. Put five people without masks in a 400 square foot room with closed windows, and it becomes unsafe after 33 minutes.Bazant says studies on super spreader events show in indoor environments, the distance from an infected person doesn’t matter. Infected droplets spread and mix throughout the room like second-hand smoke from a cigarette.But with masks trapping droplets and diverting them upwards like a chimney, an environment like an airplane could be safe for several hours, according to the model. With more than 95% of the passengers and crew wearing surgical masks, a Boeing 737 could support 200 people -- around full capacity depending on the configuration -- for 18 hours. 2850

SAN DIEGO (KGTV) - Most school districts in San Diego County are still figuring out how to reopen classrooms in the fall. On Wednesday, the Office of Education released new guidance on how districts and charter schools can do that safely. They put out comprehensive guidance that includes recommendations to alter many aspects of everyday life for parents, students, and teachers. It includes symptom screening, altering classroom layouts to support physical distancing. They also recommend frequently cleaning common areas, wearing face coverings, and restricting visitor access. RELATED: San Diego Unified School District approves fall reopening planMusic Watson says they've had to rethink every possible scenario. "Recommendations about not using water fountains because of the multiple touches there, or about spacing desks as far apart as practicable so that you can have distancing," said Watson, Chief of Staff with the Office of Education. On Tuesday, the San Diego Unified District approved their reopening plan. It would allow parents to decide whether or not to send their kids back to campus or continue online learning at home. RELATED: San Diego schools allowed to hold on-campus classes under new rulesBut, most districts we reached out to are still working on their plans. The Grossmont Union High School District says they're currently conducting input sessions with focus groups. They tell ABC 10News they hope to have a plan in place for board approval by early to mid-July. The Poway Unified School District says they'll have a plan by June 25. Their superintendent released survey results with parents, showing 59% of families want students to return to campus full-time. Meanwhile, 41% say they would prefer a blended or virtual learning option to continue. RELATED: State provides school guidance to reopen, up to local districts to implementThe Escondido Union High School District says they hope to release a plan by June 30. The Sweetwater Union High School District is hosting a virtual town hall on June 18 where parents can give input on what changes they hope to see. For 42 districts and more than 100 charter schools in San Diego County, the next school year will look very different. "Have a way of keeping records so that if someone ends up testing positive you can do the contact tracing to be able to go back and figure out with whom they've had contact," said Watson. "We really wanted to plan for every eventually, every possibility so that schools can be prepared."The Office of Education also recommends all schools keep the option of distance learning for families who prefer it. 2630

SAN DIEGO (KGTV) — President Trump wants to restart the U.S. economy by April 12, but multiple economists, governors and health officials are expressing skepticism about that date amid efforts to flatten the curve of coronavirus infections.Still, the longer the shutdown lasts, the harder it will be for businesses to get up and running, economists say. Alan Gin, an economist at the University of San Diego, said if this lasts through April, it should be survivable for many businesses. However, anything beyond that could render reopening less likely."Some businesses are not going to be able to hang on, even with the help that is coming from the federal government, so they will end up closing for good," Gin said. San Diego's economy is hurting as thousands of restaurant, retail and hotel workers are laid off amid the coronavirus restrictions. Meanwhile, the people who are working from home have very few places to spend their money. Jessie Medina, who opened the Femx Quarter co-working and event center in Mission Hills in November, said her business is out ,000 and she had to put two new hires on hold. "We were getting traction, growing, and all of a sudden it's like, stop," she said. "I really want our doors to open, I don't know how much longer businesses that have these liabilities every month can stay open if they're not making money."Medina said she is trying to do her part by taking out from locally owned restaurants and buying from local sellers, but with her very limited income, she can only do so much. The Workforce Partnership reported Friday that more than 13,000 San Diego workers have been laid off, furloughed or seen their hours cut. Those layoff notices are temporarily no longer required law, so the actual number could be much higher. 1784
