SAN DIEGO (KGTV) - Ricardo Silva, a Chula Vista native, has it in his blood to both serve his country and join the medical field.He had multiple family members join the military and as a San Diego local, he grew up around the Navy, so he became a sailor about ten years ago. Growing up with a mother who was a nurse, it makes sense that he and his sister followed her lead. His sister now works for the Public Health Department and he’s working at Naval Hospital Bremerton in Washington with the preventative medicine team as a contact tracer for COVID-19 patients.He and his team have worked days as long as 18 hours since the start of the pandemic, figuring out where patients contracted the virus.“It’s very very detailed, trying to figure out where they got it and how to try to prevent that from happening for the next person,” he said.Naval Hospital Bremerton has screened more than 35,000 patients as of July 30.“As I do this work, as tough as it is, when this is all over I just want to be able to say I did my part to help get through this,” he said. 1067

SAN DIEGO (KGTV) — Researchers at the University of California, San Francisco are working on a spray designed to block the novel coronavirus from hijacking cells in the body, like a biological mask or internal personal protective equipment.They’re doing it by borrowing a defense mechanism from an unlikely source: llamas.The team, led by UCSF graduate student Michael Schoof, engineered a synthetic molecule based on one found in a llama’s immune system that acts like an antibody but is one-tenth the size.Human antibody treatments, known as convalescent plasma, require a transfusion in a hospital setting. But this smaller molecule, called a nanobody, can be easily self-administered via an inhaler or nasal spray and rapidly manufactured using yeast, Schoof said.The scientists named their product AeroNabs. They say it could be an inexpensive intervention for treating and preventing COVID-19 while the world waits for a vaccine.“We don't know how effective vaccines will be. We don't know how long it will take to rapidly deploy them, so we envision this product as hopefully a bridge until there is widespread, effective vaccination,” Schoof said.Once a vaccine is available, AeroNabs could offer protection for individuals who are unable to be inoculated for health reasons, he said, or an early treatment option.The team is in talks with commercial partners and hopes to begin clinical trials soon.In the 1980s, Belgian scientists discovered that about half of the antibodies in camels, llamas and alpacas are shaped differently than the antibodies found in other mammals, including humans. Researchers later learned they could use a fragment of these oddly shaped camelid antibodies to bind to antigens.Those fragments are called nanobodies.Currently, there is only one FDA-approved drug that uses nanobodies. Caplacizumab was approved last year to treat a rare blood disorder.The team at UCSF sifted through billions of nanobodies to find one that binded best to the spike proteins on the coronavirus, then engineered it to stick even better.The coronavirus uses its spikes to enter cells and replicate; the spikes are essentially the pathogen’s key into the body. By coating the spikes with nanobodies or antibodies, the viral key no longer fits into the body’s receptors and the virus can’t get in.“This works in the lab. It needs to be translated into the clinic,” said Schoof.The team at UCSF still needs to figure out the best delivery method, whether it is a nebulizer, an inhaler or a nasal spray. 2524

SAN DIEGO (KGTV) -- San Diegans will soon have four new restaurants for dining along the San Diego Bay, as Mayor Kevin Faulconer joined Port of San Diego officials and The Brigantine Inc. for the ribbon cutting ceremony Monday for Portside Pier. Portside Pier is an over-the-water dining complex that has been years in the making. It will have four restaurants -- Brigantine on the Bay, Miguel's Cocina, Ketch Grill & Taps and Portside Coffee & Gelato. The dining complex replaced Anthony's Fish Grotto, a staple for 52 years along the bay. The dining complex is now owned by The Brigantine Inc. The restaurants are opening amid the COVID-19 pandemic. The design of the restaurants have plenty of outdoor space to seat about 500 people, with all social distancing guidelines in place. The complex has capacity for about 1,000 people, once pandemic restrictions are lifted. Portside Pier is the first of several projects along the waterfront, to improve and update the embarcadero. The coffee and gelato bar are already open. The other restaurants officially open on July 28. 1090

SAN DIEGO (KGTV) -- San Diego County health officials are reminding those who received a hepatitis A shot in October that it’s time for a second dose.Communities have out more than 138,000 doses in the year since the hepatitis A outbreak began.New cases have dropped significantly but health officials say the outbreak is still ongoing. Receiving the second shot boosts immunity from 20 to 40 years.RELATED: Hepatitis A emergency officially ends in San Diego County Residents can get their second dose for free on Friday, April 27 at the Old Town Visitor Center on San Diego Avenue.

SAN DIEGO (KGTV) — San Diego Police Officers are patrolling the College Area, cracking down on noise and health order violations as San Diego teeters on the edge of the red tier for coronavirus restrictions.Friday eight cease and desist orders were issued to College Area houses. The reason being the residence "intends to hold large gatherings on Oct. 30, 2020, - Nov. 1, 2020, in blatant violation of the Order of the State Health Officer, the County Order of the Health Officer and Emergency Regulations, and CDPH's October 9, 2020 gathering guidance."Saturday on Dorothy Drive near Dorothy Way it was easy to hear music, excited yelling, and chatter from multiple homes. A steady stream of young people came and left various houses.Normally, Jean Hoeger says it gets pretty wild, but when she went out Friday, "it was pretty quiet you didn't see the hoards of kids walking on the street which is kinda common in the College Area."Hoeger is a representative of the College Area Public Safety Committee."There were parties but they all seemed to be inside small groups, loud noise was not really present so nothing you could call into the police department for a noise disturbance," Hoeger said. She said she was proud the students seem to be abiding by the rules, saying, "If they're partying inside their houses with their little group of friends that's fabulous!"Hoeger said huge parties are the most "disconcerting to us any time of the year because it's just disruptive to the whole neighborhood, when they leave most of them are drunk and unfortunately a lot of sexual assaults happen."Any San Diego State students found violating the university's Stay Home order, which lasts through Monday, Nov. 2 at 6 a.m., could face disciplinary action, up to expulsion.Since Aug. 24, SDSU has issued nearly 970 violations, according to a statement from the university."They should be afraid of the consequences of their actions, whether related to COVID or in regards to the San Diego Municipal Code with regard to noise," Hoeger said.Violating the cease and desist orders could result in a misdemeanor offense and a ,000 fine. 2135
