SAN DIEGO (KGTV) — With California setting single-day records this week for COVID-19 cases, experts say it’s important to keep in mind that some activities carry a higher risk of transmission than others.To gauge risk, it’s helpful to think of it like an equation, said Dr. Tyler Smith, a professor and epidemiologist at National University.First, consider the environmental factors like whether the activity will be indoors or outdoors and the number of people likely to be present.Then consider the likelihood of successful safety measures: whether people will wear masks, clean surfaces, and maintain six feet of distancing.Compare those two datapoints, and you can assess the overall risk of an activity, Smith said.A good example of the importance of this equation is the dentist’s office, our experts said.On one hand, the environmental risk factors are high. Working in someone’s mouth with drills can aerosolize particles that carry the virus.But dentists are likely to strictly observe public health countermeasures like personal protective equipment and sanitization, to balance out the risk equation.“Our doctors offices and dental offices are really some of the safest places right now,” said Dr. Georgine Nanos, a family physician who specializes in epidemiology.Dr. Smith agreed: dental offices are low risk.The likelihood that participants will wear masks is a critical part of the safety equation, according to Dr. Nanos.“What [the medical community] didn’t know four months ago is that wearing a mask can reduce the risk of transmission and catching COVID-19 by sometimes up to 60 percent if both people are wearing masks,” she said.Gyms are an environment where some may try to avoid wearing a face covering during a challenging workout.“If you can be 6 feet apart from your neighbor, that would be ideal. I wouldn’t recommend a hot yoga class where people are crowded together and not a lot of ventilation,” Dr. Nanos said.If you can maintain distance and bring your own sanitizer, ideally in a room with high ceilings and good ventilation, Dr. Nanos grades gyms medium risk.In the high-risk category, experts agree bars pose a particular challenge. Not only is there a chance you could encounter a large crowd indoors, alcohol could discourage social distancing efforts.Also high risk: casinos. In addition to alcohol, casinos have an environment with a lot of touchpoints like slot machines and chips. Many also allow indoor smoking, which could complicate health matters, Dr. Nanos pointed out.But the highest risk activity, according to both experts, is protests and rallies.“That many people together, not distancing, rarely wearing masks and yelling,” Dr. Smith said, That to me is terrifying as a public health professional.”They put large protests and rallies at the top because unlike other environments, there is no one in charge with a financial stake in maintaining public health countermeasures.Dr. Smith said any of these activities have the potential to be operated safely.“It just has to do with people realizing they have to adhere to these mandates. If so, all these things can be open. We’ll still have cases but it won’t overwhelm our healthcare system,” Dr. Smith. 3212

SAN DIEGO (KGTV) -- With a shortened and fanless baseball season underway, there is still confusion and legal challenges over refunds for tickets.Sydnie Gallegos lives in San Diego, but she is a loyal Dodgers fan. Every year, she and moe than a dozen of her family members see a game live at Dodgers Stadium. “We do it once a year, every year, for the last six years,” Gallegos said.Gallegos, like so many others, were left in the dark wondering what to do about tickets they bought.Her family bought tickets to a July 4th game back in March. “It was for 15 of me and my family members. That’s over ,400 just in tickets,” Gallegos said.Although Major League Baseball announced refund policies in April, Gallegos said they didn’t hear anything until July. They received an email from the Dodgers, offering ticketholders “with an account credit for all 2020 tickets and parking (plus applicable fees).”The team also added a 10 percent bonus credit, which could be applied for the 2021 season. A spokesperson for the Padres also said they’re also offering fans a refund or use their credit towards the 2021 season.Despite refunds now being issued to fans, a class action lawsuit over the issue continues. Several ticket buyers sued Major League Baseball, the teams, as well as StubHub, Ticketmaster, and Live Nation. The attorneys for the plaintiffs said they are still moving forward with the lawsuit because they “continue to pursue their claims so that each ticket purchaser for the MLB 2020 season will receive a full refund as soon as possible.”“As the season will have no fan attendance, Defendants have no reason to keep any of the ticket purchasers’ money,” attorney Blake Yagman wrote to Team 10. 1712

SAN DIEGO (KGTV) - With so many families feeling the financial impact of COVID-19 this year, a Linda Vista family is hoping to quietly bring some holiday cheer to neighbors by taking on the role of Secret Santa.Jaelyn,13, Jayda, 11, and Jessica, 4, will be doing plenty of wrapping this holiday season. Their mom Rhian and her partner, Jeff Leardini, are determined to deliver some holiday cheer."There are so many families that are worried about how they're going to make it to tomorrow. Christmas is the last thing on their mind. We want to take that worry away," said Leardini.Leardini posted on the Nextdoor app an offer to buy and wrap a Christmas toy for any neighbors in need, no strings attached. Leardini, a sales manager for a pet supply company, and his girlfriend, a nurse, kept their jobs during the pandemic."We feel very fortunate and want to help people," said Leardini.During this holiday season, his family are now playing the part of Secret Santa."We just thought there are people that might be embarrassed to go to organizations, so we thought can we help them without them having to go through a lot of red tape," said Leardini.So far, a handful of neighbors have responded to his offer"It's been really emotional reading the messages," said Leardini.Some are dealing with lost jobs, others with COVID-related health issues. Those families will soon receive something extra under the tree."Want to deliver smiles to them, even if it's just for one day. Their children will be happy, and that in turn will deliver joy to their family. That's our hope," said Leardini.It's a big hope, but not the only one."My hope is that people will see my post and be inspired to help others within their own community," said Leardini.Leardini hopes to buy and wrap several dozen gifts.If you know of a family that could use Leardini's help, email us at Tips@10news.com 1882

SAN DIEGO (KGTV) — UC San Diego says it plans to begin repopulating its campus this summer, with about 30% of courses being held in person this fall.The campus says in-person classes will be limited to less than 50 students per class or 50% classroom capacity, whichever is lower. Any classes with more than 50 students enrolled will be offered remotely.Some classes will also be held in a hybrid format. The fall quarter is set to begin on Sept. 28, with student arrivals to campus being staggered to protect the capacity for testing."We aim to mitigate risk in a way that will allow UC San Diego to provide an environment for learning and offer a university experience that our students expect," said Chancellor Pradeep Khosla. "As one of the nation’s leading research universities, we have risen to meet difficult circumstances and responded with innovation every step of the way."For students attending in-person classes, facial coverings will be required, according to the school. Students will also be tested for COVID-19 monthly and when moving in on campus.UCSD plans to offer regular coronavirus testing to students, faculty, and staff, with higher frequency in testing for those who are at higher risk for infection. The campus says there will be no cost for asymptomatic or symptomatic testing for students, faculty, and staff when done at a UC San Diego Health location or through Student Health Services.“Our adaptive model considers the most current science on transmission and infection risk and will drive our determinations on the testing frequency of our various campus populations,” said project lead Natasha Martin, associate professor of medicine at UC San Diego School of Medicine. “We wanted a simple, easy testing process which can be delivered at scale in the fall to ensure widespread testing for early outbreak detection.“Our simulations indicate that if more than 75 percent of the population were tested per month, we would be able to detect an outbreak before there are 10 detectable infections on campus,” she said.Students aren't thrilled at the impact the coronavirus is having on their college experience."You can't really make new friends and meet new people and do many projects strictly online," Dylan Nelson said. He will be an incoming Junior at UC San Diego. This summer his internship in New York was also put on hold due to the pandemic, but he's finding the silver lining."Fortunately all [my classes are] computer based classes, so a lot of that was going to be online anyway so it's not too hard to adapt," adding, "as a Junior I think it's tough but not the worst, I feel bad for all the Seniors going in right now because you're missing out on potentially really big classes."ABC 10News asked if he would feel comfortable returning to class wearing a face covering, "for me personally no, I think for other people in certain classes they might want the more in person aspect."Nelson is hopeful for the future, saying this to his fellow Tritons, "hang in there and stay safe or this may be even longer than we want it to be." 3079
