SAN DIEGO (KGTV)-- Beginning Thursday, wearing masks has become a state mandate. A new study out of the University of California, San Diego, suggests the best way to curb the spread of coronavirus is by wearing a mask.In a UCSD campus-released article titled "To wear a mask or not, is not the question; Research indicates it's the answer," Chemistry Nobel Laureate and UCSD Professor Mario Molina shows the data does not lie."Let's work with the scientists," Molina said. "Let's work together with society!"RELATED: San Diego County exceeds community outbreak trigger, forcing pause on future reopeningsHe and a team of scientists at CALTECH and Texas A&M looked at the world's three COVID-19 epicenters: Wuhan, Italy, and New York City. They studied each area's attempts to mitigate the spread of COVID-19, including shelter in place, social distancing, and wearing facial coverings.Their study showed, in Wuhan, where mask-wearing is part of the culture, the spread was relatively slow. But in Italy, even after the lockdown, positive cases continued to climb. Additionally, despite the stay-at-home order in New York City, numbers continued to rise.A pivotal point of the study was when they looked at the numbers in Italy and New York after their respective mask mandates went into effect on April 6, 2020, and April 17, 2020. It was only then that the spread of viral air particles slowed drastically.RELATED: California requiring face coverings for most indoor areas"It changes. It's no longer straight. It goes downwards," Professor Molina said, referring to the curve on the bar graph.The professor reminds people that this does not mean to ignore all the other health measures."We are not saying using masks is the only thing that matters, no," Professor Molina said. "What we have in the paper is, everything is added to social distancing and to quarantine."RELATED: Mayor releases outdoor dining proposal in Little ItalyProfessor Molina says California's new facemask mandate is similar to government regulations on air pollution but on a much personal scale. In this case, you are the car, and COVID-19 is pollution. He says he is hopeful that with the mandate, the numbers in California will decline."We tell people, 'Hey, it's a good idea to wear face masks. You protect your family, and you protect yourself!'" Molina said.Molina says a secondary research paper analyzing mask mandates in different states will be published in the coming weeks. 2472

SAN FRANCISCO (AP) — Facebook threatened to block Australian publishers and individuals from sharing news stories on its platform in reaction to an Australian measure that would require it to compensate media organizations for its use of their stories.The social network said the move would force it to pay arbitrary and theoretically unlimited sums for information that makes up only a small fraction of its service.Google has cast the proposed Australian law as a potential threat to individual privacy and a burden that would degrade the quality of its search and YouTube video services, but did not threaten a cutoff.Australia's government hopes the legislation will be passed this year. 699

SAN DIEGO (KGTV) - With home prices skyrocketing San Diegans are turning to remodeling.However, if the home has lead paint or asbestos, it can become a health hazard if not handled correctly. The Environmental Protection Agency is cracking down on companies breaking the rules.The agency has taken action against six companies in Arizona and California for allegedly violating regulations requiring them to protect the public from exposure to lead. The companies paid a combined 7,000 in penalties.According to the EPA, "an inspection found that, between 2014 and 2015, Renovation Realty performed renovation work at six homes in San Diego and Santee without being EPA-certified to perform work in pre-1978 housing where lead-based paint is assumed to be present." The agency says the company also failed to keep records indicating compliance with lead-safe work practices and did not ensure a certified renovator was involved as required."Looking back at it, it was a painful expensive experience to get fined by the EPA" said Keith Christian CEO of Renovation Realty.Christian said, at the time, they didn't understand the EPA's requirements of how much square footage you can disturb per room."We got fined, we paid the fine, we all went to a class we got certified as a company our supervisors got certified and it's been a great experience,” Christian said. “So now that we understand the process we incorporated that into our renovation.”Across the county from October 2016 through September 2017, the EPA finalized 121 civil settlements for alleged violations of at least one of the lead-based paint rules. The settlements they obtained in the cases soared past one million dollars. The EPA requires companies who perform abatement projects in pre-1978 homes to be certified and follow specific work practices.“For a homeowner, the biggest thing is their liability,” said Tim Tilley with Superior Abatement Services Inc. “If they hire a contractor who doesn’t follow the rules, the regulatory agencies will generally cite everyone in the food chain.”Tilley removes hazardous material like lead and asbestos for a living. His team is currently working on a San Diego home that tested negative for lead but positive for asbestos.Tilley tells 10News rules put in place at the federal level down to the local level are there to protect employees and consumers."For a homeowner, it's really important to ask the right questions,” said Gregg Cantor with Murray Lampert Design - Build – Remodel.Cantor says consumers should know if the contractor is licensed and certified and trained to perform hazardous materials work.Consumers also want to ask about types of safety methods they use, digging into specific safety precautions before, during and after the work is done. You should know what dangers you're dealing with before demolition begins.Renovation Realty is now certified with the EPA, and that extra step is helping business."We’ve finished about 490 homes since we were certified in September 2015, and we’ve actually received contracts because we’re EPA certified,” Christian said.Click here to learn more about reducing childhood lead exposure, or to learn more about the harmful effects of asbestos, click here.  3257

SAN DIEGO (KGTV) -The extended patio seating in the Gaslamp Quarter is here to stay for now, according to the Gaslamp Quarter Association.Thanks to a special events permit, as long as social distancing is required, restaurants will overflow into the streets with patio dining Thursday through Saturday each weekend through the end of the year.Manager at The Field Phil Nestor was thrilled to see how busy it was Saturday, saying the patios made a "100%, a million times over," difference to recuperating after being shut down during the pandemic.He said people feel more comfortable sitting outside, and diners said they enjoyed the atmosphere."I think it's actually a pretty good idea, it reminds me of my time in Europe so I think it's pretty cool," Luis Morales said.Fifth Avenue shut down between G and L Streets Thursday through Saturday to make way for the patios, and was slow to start."I think the first day everyone was finding their feet I guess, they were seeing how many tables they could put in their area," Nestor said.By Saturday nearly a dozen restaurants expanded into the streets.Morales said they enjoyed themselves, "we came out to get together with the boys and just finally get a sense of normalcy."Right now normalcy comes with hand sanitizing stations at each table and masks while you're waiting to be seated."I always take my precautions," one diner said. The man said he came down from Los Angeles to celebrate his birthday and felt safer in San Diego compared to up north where Orange County reduced their mask policy to "strongly recommended."Last weekend images of crowds not social distancing, or wearing masks in the Gaslamp Quarter garnered harsh words from County Supervisor Nathan Fletcher. He said earlier this week targeted enforcement would ensure this doesn't happen again.Nestor said the weight falls on restaurants to enforce the county's policies, "we're responsible for our patio and the surrounding areas and making sure people are in the line wearing masks and they're social distancing.""You can't just run into the street and tell someone to do something but you're doing your best and I think most people whether they're drunk or not, I think taking responsibility for themselves too which is a good thing to see," he said.He and other businesses are hopeful as long as the patio dining is successful and they keep everyone healthy this could become a more permanent fixture."I hope it becomes a permanent thing, a lot of the restaurants do," Nestor said, hopeful business will continue to climb, helping them recover from the pandemic. 2592
