SAN DIEGO (KGTV) - Students in the San Diego Unified School District have a handful of programs designed to keep them active and help ward off childhood obesity.In 2016, the district began it's Healthy Initiative. So far, they've created wellness committees in every school. They also put their IMPACT Program into 20% of the campuses, with plans to expand in the next few years."IMPACT stands for Increased Movement in Physical Activity during Class Time," explains SDUSD's Kate McDevitt. It gets the students 30 extra minutes each week outside, learning easy-to-replicate activities that they can take home."They still have time with their PE teacher, but now classroom teachers can engage their students in station based physical activity," says McDevitt. She says it helps with their focus throughout the day."You can see them light up and really engage in the classroom activities and the earning they’re doing when they have time to move," she says.In addition to the IMPACT program, many schools have local gardens where kids learn about fresh fruits and vegetables. Cafeterias have replaced traditional, high calorie options with foods that are healthier. And some schools have changed the way they do celebrations."We have healthy celebrations," says Ocean Beach Elementary Principal Marco Drapeau. "We still celebrate birthdays and holidays. We still make a big deal out of them. But we don’t hand out the sugary treats."The need for a more health-based approach to school comes at a time when kids' risk of obesity is increasing. According to the CDC, one in five kids in the US is obese. And one in three kids born since 2000 will develop Type 2 Diabetes over the course of their lives.Drapeau says schools are on the front lines in the fight."We’re at a stage right now where we’re competing with this," Drapeau says, holding his hands as if he's holding a phone and watching tv. "We want the kids to understand there’s some real viable options for them outside staring at a screen." 2005

SAN DIEGO (KGTV) — The environmental community is concerned that individuals using masks are disposing of the face-covering properly.Dimitri Deheyn is a Scripps Institution of Oceanography research scientist and studies biodegradable objects, something disposable masks are not. He said around the world, researchers are seeing an increase in trashed masks on beaches, which will ultimately end up in the ocean and harm wildlife and our ecosystem.In addition, when the disposable masks are thrown away, the string can become a danger to animals if not cut, so he said if you have to use disposable masks, cut the string that goes around the ear.Deheyn has been working with a company based in Austria called Lenzing that typically makes eco-friendly comfortable clothing from fibers that can degrade, making them better for the environment. He said the company shifted to making biodegradable masks when the pandemic hit, and he’s helped test them.“Basically test them, we put them in the seawater and see if they degrade and yes they degrade,” he said.He said there are U.S. companies that make a similar product, and this is what people should be wearing instead of disposable masks. He said reusable masks are another solution to helping save the environment.“If you are acting as an individualistic human being, and you oppress nature, at the end this could be very bad for us as a human society,” he said, encouraging everyone to do their part. 1457

SAN DIEGO (KGTV) — The Centers for Disease Control and Prevention announced Thursday it is extending a ban on cruise ships operating in U.S. territory through September.The ban was set to end next week, but the agency extended the ban as coronavirus cases rise in 40 states.Florida and California, where many cruises originate or end, both set records for new daily COVID-19 cases recently.RELATED: As cruise ships idle, San Diego region lost up to millionThe CDC says the ban on cruise ship operations will be in effect until, "the expiration of the Secretary of Health and Human Services’ declaration that COVID-19 constitutes a public health emergency," "the CDC Director rescinds or modifies the order based on specific public health or other considerations," or Sept. 30.Some cruise lines had already canceled scheduled sailings until Sept. 15 over ongoing discussions with federal officials on how to restart business safely, the Associated Press reported.The Port of San Diego estimates that each cruise ship that visits San Diego generates about 0,000 in regional economic impact, including local shopping, restaurant businesses, and other expenses.Nearly 30 cruises were canceled due to the pandemic, costing about million in lost revenue for the Port of San Diego alone, according to Brianne Page, a public information officer for the Port of San Diego. The cost to regional economic impact could be as high as million.The Associated Press contributed to this report. 1499

SAN DIEGO (KGTV) — The back-to-back announcements of promising clinical trial results from Pfizer and Moderna may usher in a new era for vaccine technology.Both companies have candidates that rely on a new kind of vaccine strategy: RNA. Preliminary data show both candidates are more than 90 percent effective.On the surface, the vaccine candidates look like any other you’ve taken. They work by training your body to build up defensive weapons against a virus, like antibodies and T-cells.But instead of training your body by introducing a killed virus or a fragment of a virus, the vaccines from Moderna and Pfizer introduce a set of instructions called messenger RNA enclosed in a little blob of fat.“The key concept of RNA is that they’re messages, and they’re meant as short-term messages,” said Dr. Shane Crotty of the La Jolla Institute for Immunology.Crotty said there are 5,000 to 10,000 messages within a cell at any given time.Once administered, the mRNA in the vaccine instructs some of your cells to make the coronavirus’ signature spike protein. The spike protein on the surface of the coronavirus allows it to infiltrate and hijack cells.Even though the spike protein is just one of about 25 genes the virus has, preliminary results from the clinical trials suggest it is enough material to train the immune system without making the recipient sick.Crotty likened the process of training the immune system to spotting a sedan. If the coronavirus is a car, the spike protein might be the door.“There's no way that car door could turn into a whole car, but it's enough of a piece of a car for your immune system to recognize that car if it saw it again,” he said.Scientists started by sequencing the virus’ DNA from a sick patient, then encoding that genetic sequence into an mRNA instruction molecule that can be read by the manufacturing part of cells.From there, Dr. Crotty said it’s a bit like the messenger app Snapchat.The mRNA gets injected into the body, sending temporary instructions to your cells that last for a while, then disappear. mRNA does not genetically modify cells, he stressed.“They’re around as messages for some period of time and then they go away, and the cells get back to their normal job of reading their own messages instead of reading the messages you’re injecting in the vaccine,” he said.The concept has been around since the 1990s, but there are currently no RNA vaccines on the market for any pathogen, so Dr. Crotty said it’s hard to estimate how long their protective effects will last.Some vaccines offer a lifetime of protection, like the measles vaccine. Others offer decades of protection. The flu vaccine only lasts about six months.Dr. Crotty said the length of protection depends on how fast the virus mutates and how long the immune cells survive in the body.But even if the COVID-19 vaccine turns out to need an annual update, he’s optimistic. The best feature of RNA vaccines is that they can be quickly reprogrammed.Both Moderna and Pfizer are still in their Phase 3 trials, but they expect to finish them by December. Together, they estimate they’ll have enough doses for about 35 million people by the end of this year, primarily for healthcare workers and high-risk individuals. 3250

SAN DIEGO (KGTV) -- The former Imperial Beach man convicted of molesting and strangling two young boys in 1993 has died of coronavirus, the California Department of Corrections and Rehabilitation said. Scott Thomas Erskine, 57, was sentenced to death in San Diego County in 2004 for the first-degree murders of 9-year-old Jonathan Sellers and 13-year-old Charles Keever.The California Department of Corrections said Erskine died from complications due to the virus at an outside hospital. He was on death row at San Quentin. Both Sellers and Keever disappeared while on a bicycle ride near their South Bay homes. Erskine lured the victims to an igloo-shaped “fort” of brush before molesting and strangling them.In March of 2001, Erskine was serving a 70-year sentence for raping a San Diego woman when newly-tested DNA linked him to the murder of the boys.Erskine also pleaded guilty to a second-degree murder for the Florida slaying of 26-year-old Renee Baker. He was sentenced to life without parole for that murder.City News Service contributed to this report. 1072
