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) — One of the joys of Christmas is waking up to a stocking filled with gifts. As a child, it's part of the wonder and magic of Santa.Even as we grow up, many people keep the tradition alive, simply because a Christmas stocking touches the child in all of us.And it's from that attachment, that an act of kindness was born.As a teenager, Jane Wesley Brooks began filling Christmas stockings for the homeless, and delivering them to those on the streets each Christmas Eve.Over 40 years, she has passed out thousands of stockings filled with caps, mittens, socks, shampoos, magazines, and even playing cards. Any small item that is new, clean and useful for those without a home.We surprised Jane with 10News Leadership Award.She accepts any appropriate new item at her law office all year long. Magazines are the only exception. They can be gently read prior to delivery.Here’s where you can donate:Jane Wesley Brooks, CFLSJWB Family Law1620 Fifth Avenue, Suite 600San Diego, CA 92101Phone: 619-234-6123 1026

SAN DIEGO (KGTV) - On Monday, San Diego County supervisors met privately to discuss options if the county is moved back into the most restrictive tier.Although the meeting is taking place behind closed doors, it's not stopping them from sharing their frustrations publicly.At a press conference on Monday morning, Supervisor Nathan Fletcher called the actions of two of his fellow board members reckless and irresponsible."Supervisors Jim Desmond and Kristin Gaspar are inciting a fight between government and small business," Fletcher stated. “They are exploiting the pain and suffering the small businesses are going through as a result of the global pandemic as a wedge for political gain."Responding to the statements made at the press conference, Supervisor Kristin Gaspar said that she's never supported an approach to reopening that was not supported by the Public Health Officer and clinical leadership team.In a statement, Gaspar wrote, "Supervisor Fletcher knows this but prefers to continue spreading this false narrative because he is actively running a campaign against me. I measured the distance between our office doors, and it is 7 feet, so he and I can actually have a socially distanced conversation anytime he isn't holding a press conference."The public display of animosity comes as supervisors continue to discuss different options, including taking legal action against the state, to prevent potentially sliding back into the most restrictive risk level.Fletcher is against any potential legal action; Gaspar is for it.A spokesperson from Supervisor Jim Desmond's office said Desmond is weighing the options and waiting to hear any potential ramifications.On Monday, Supervisor Dianne Jacob told 10News, "I will do what is legally possible and where we are on solid legal ground. We do have a good solid legal option here."Jacob said the colleges and universities have a choice whether to allow students back on campus and hold in-person classes. She explained businesses have no choice, and she will fight to keep them open.A spokesperson for Supervisor Greg Cox told ABC 10News they wouldn't comment before the closed-door meeting.Legal actions by citizens and government entities against the state aren't uncommon.ABC 10News has reported on businesses and churches suing Gov. Gavin Newsom.At the end of July, the Orange County Board of Education voted to file a lawsuit against Gov. Newsom and the California Public Health Officer to seek a court order that sets aside the state orders preventing public schools from holding in-person classes and resuming services on campus."There's precedent from before the pandemic and during the pandemic for the county and other local governments to file suit against the state government to try to get the courts to weigh in on who holds the reins," said Lindsay Wiley, Professor of Law at American University Washington College of Law.Wiley said if the county did file a lawsuit, it's likely the courts would defer to the governor based on recent rulings."These cases are unpredictable and there's a fair bit of discretion left to the courts to decide these issues," Wiley said. "It's hard to say much given that we haven't seen what the complaint is that the county might bring but for the most part the general trend has been to uphold reasonable orders of this type." 3346
