Staff provided students with water during the outage. Hand sanitizer and baby wipes were also given out. 438

SAN DIEGO (KGTV) — San Diego County health officials say the county’s contact tracing program has not been hampered by the same issues plaguing efforts in other areas like New York City, but there may be blind spots in the county’s data.One of the keys to successful contact tracing is eliciting a full list of close contacts from an individual who tests positive. A “close contact” is defined as someone who was within 6 feet of an infected person for at least 15 minutes, beginning 48 hours before illness appeared and lasting until the patient was isolated.It’s sensitive work, but the breadth of that list is critical to suppression efforts. “By identifying or ‘tracing’ the contacts of people infected with COVID-19, we can identify other individuals who might be infected, test those individuals for infection, treat those who are also infected and trace their contacts as well,” the county says on its website.However, in New York City, only 35% of the residents who tested positive actually provided information about their close contacts to tracers during the first two weeks of June, the New York Times reported.That means that even if tracers were able to reach virtually all of the individuals on their list, they would still likely have a vastly incomplete picture of those who may be at risk.That’s where San Diego’s first potential blind spot comes in. Unlike New York City, San Diego County is not actively monitoring the percentage of individuals who provide information on close contacts to tracers, County Medical Director Dr. Eric McDonald said Monday.“We don’t specifically follow that metric,” he said. “We think we’re probably doing better than the numbers you hear from New York. It’s difficult though for us to drill down on that specifically.”Instead, the county bases one of its triggers on attempts to reach the close contacts it has on file, regardless of how complete or incomplete that list may be, and regardless of whether tracers actually got in touch with those individuals -- a second potential blind spot.McDonald acknowledged that tracers are often given out-of-date or inaccurate contact information, and must rely on public records and other sources to try to reach out to close contacts.As of Monday, the county had attempted to contact 87% of known close contacts within 24 hours, well above the county’s goal of 70%.“I think we’re doing pretty well from the contact tracing perspective,” McDonald said of that metric.“I would say the general gestalt from talking to our contact tracers is that most individuals are actually quite cooperative and do give as best information as they can about close contacts. And we really do appreciate that,” he added.McDonald said that staff would reexamine the county’s database in light of the inquiry by ABC 10News, and on Tuesday a spokeswoman provided an update. “Approximately 60 percent of our cases identify one or more close contacts,” said communications officer Sarah Sweeney.Assuming that every person who tests positive has at least one close contact, it means San Diego County disease detectives are placing calls to -- at most -- 52% of close contacts within the first 24 hours.McDonald said while that tracers do not get close contact information from everyone, there are circumstances when a close contact is simply a household member and has no other unique close contacts to follow up on.“Some close contacts don’t need to be identifying any other close contacts,” he said. “Overall, I would say that our cooperation is good to excellent.”From May 4 to May 28, people who tested positive in the county identified an average of 2.2 close contacts, County Public Health Officer Dr. Wilma Wooten said at a Board of Supervisors meeting earlier this month.Whether tracers actually reach those individuals is another story.“I’m a person who thinks it would be great to have perfection: every single person telling us every single thing that they know. But I think that we are doing very well from the information we are getting from our close contact investigations,” McDonald said Tuesday. 4089

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 Diego is getting its first round of Pfizer vaccines to fight the coronavirus next week, but the vaccine is recommended for those 16 years and older.Many parents are concerned about what that means for their children and going back to school."Essentially the Pfizer vaccine wasn't studied in kids under 12 but we are going to see more study in them," Dr. Abi Olulade, with Sharp Family Medicine said.While Pfizer is working on a child-safe vaccine, their competitor Moderna started testing their vaccine on 12-17-year-olds Thursday.Dr. Olulade sees the newly approved Pfizer vaccine as a lifeline, "we have a weapon now in the war against this virus and we're all breathing a huge sigh of relief."The vaccine a relief for our healthcare system swamped with coronavirus patients.When a shot is approved and safe for kids, Dr. Olulade said it's important parents have their kids vaccinated."Vaccines have a very long and proven safety record in kids," Dr. Olulade said. When asked what is the risk of waiting to get your child vaccinated, she replied, "death and long term effects of COVID, overwhelming our healthcare system and preventing us from providing care for other conditions that don't just stop because of COVID and so I think everyone should really really think about making sure that they get vaccinated to protect all of us."She said it's important also to get children vaccinated because they are proven super-spreaders of the virus and susceptible to harm from it."We just saw in Los Angeles the first child that died from Multisystem Inflammatory Syndrome which is a really scary thing that is new with this virus," Dr. Olulade said.Dr. Olulade said we will have to wait and see if schools require the vaccine moving forward.If your child has allergies, she said make sure you talk with your doctor before vaccinating your child."To say that this is a breakthrough and a victory for science is probably an understatement," Dr. Olulade said about the vaccine.A weapon, she said, is only helpful if we all use it, "when you get vaccinated, you're not just protecting yourself, you're protecting other people and children who may be going through really terrible things like cancer, so it's our responsibility that we all have to protect those who are more vulnerable." 2311

SAN DIEGO (KGTV) - San Diego frontline workers are getting their first dose of the Pfizer vaccine and hope with the approval of Moderna's vaccine we will achieve herd immunity soon and get back to normal.Tri-City Medical Center Emergency Room Dr. Jeff Shellenberger said he was grateful he was notified he could get his shot Sunday."It was really quick, I think I waited like two minutes," he said.Timing is critical for the Pfizer vaccine, which needs to be stored between -112°F to -76°, according to the Center for Disease Control and Prevention. Once thawed, undiluted vials may be stored at room temperature for no more than 2 hours, according to the Food and Drug Administration.Dr. Shellenberger said he felt a huge sense of relief wash over him after getting the shot."There's going to be a force field around me in a few weeks to months it's going to be amazing!" he joked. "It's really great because when I go to work I don't have to worry about any of my coworkers getting sick. Just the other day I had a patient of mine and he was a coworker and so it's always kind of scary to see that, but it's great to get to see friends and family again and not have to worry."He said it takes about 5 weeks and two shots to reach full immunity.The CDC's advisory committee voted Sunday 13-1 frontline essential workers and adults ages 75 and older should be the priority in the next round of COVID-19 vaccine distribution.Frontline essential workers include first responders, educators, food, agriculture, manufacturing, postal service, grocery and corrections workers.About 30,000,000 Americans fall into that category.They suggested the next phase, 1C, prioritizes adults ages 65 - 75, people with pre-existing conditions, and other essential workers.Initial vaccine doses already are going to residents in long-term care facilities and health care workers."Nice to report our Western States Scientific Safety Review Committee reviewed the Moderna trial and unanimously supported it's safety and efficacy," Governor Gavin Newsom said in a video he tweeted Sunday, excited to have two vaccines in their arsenal to fight the pandemic.Dr. Shellenberger just hopes everyone comes together in 2021."I think in this past year we've had a whole lot of division. A lot of us have been using technology unfortunately to sow a greater divide amongst us and I hope that this new technology this amazing vaccine that's super effective, I hope going forward in 2021 we're able to use it to bring humanity together," he said. 2523
