SAN DIEGO (KGTV) — Just a few weeks ago, coronavirus testing was hard to come by. But now, many San Diegans are finding it easier to get tested. Some are purchasing at-home test kits online, at no up-front cost.Raechel Kadoya is not a clinician, nor is she at a doctor's office. She is the co-owner of Soichi Sushi, giving herself a COVID-19 test."I want to take advantage of being proactive," Kadoya said as she swabbed her nose.Since the modified re-opening of her restaurant in University Heights, she and her staff have been cautious about coronavirus exposure. That is why she ordered the Pixel by Labcorp at-home COVID-19 test kit for her entire staff."I think that it is my responsibility as a business owner, not only to my staff but to my customers and my family, to make sure that everybody is doing business here safely," Kadoya said.This is the staff's second round of testing. Kadoya said the first one required multiple doctors referrals just to get a drive-through appointment an hour away."We were able to find a place in Lake Elsinore, so we all had to drive up there," Kadoya said.Dr. Abi Olulade, a family medicine physician at Sharp Rees-Stealy Medical Group, said the accessibility of these at-home tests is a big draw."It definitely is something that is very convenient for consumers," Dr. Olulade said.But she suggested customers do their homework before they order."They should be looking at whether or not the tests that they are using have been FDA authorized, and it's not just some random test that they found on the internet," Dr. Olulade said.As of June 12, 2020, seven at-home COVID-19 test kits have the FDA's emergency use authorization. They are:Phosphorus DiagnosticsPrivapathP23 LabsEverlywellRutgers University LabQuest DiagnosticsLabcorpTo get this authorization, the FDA requires at-home tests to have 95% accuracy in detecting positive results and 100% accuracy in detecting negative results.Insurance covered the upfront costs for Kadyoa's staff. But for those without insurance, some tests are covered by federal funds.From an accessibility and affordability stand-point, Kadoya said this is what works best for her."I want to do this every couple of weeks as maintenance," Kadoya said.Dr. Olulade also said to make sure the labs doing the testing also have CLIA certification, which sets national standards for accuracy, quality, and reliability. 2397

SAN DIEGO (KGTV) — In the race for a coronavirus vaccine, scientists often say we need more than one winner.That’s in part because different vaccines use different strategies to provoke the immune system, and each strategy has different strengths.Take the inactivated virus vaccine, an approach currently used in the vaccine against the poliovirus. In this approach, scientists take a live virus, kill it with chemicals or heat, and then introduce that viral corpse into a person.There are three groups in the final phase of human trials using inactivated coronavirus, primarily in China, according to a tracker from the Milken Institute.“The immune system can tell the difference between something that's a real threat and something that's not a threat, and so if you get injected with a dead virus your immune system has the tendency to not pay a lot of attention to that,” said Dr. Shane Crotty of the La Jolla Institute for Immunology.The downside of the inactivated virus approach is that it only elicits two out of the three of the parts of the immune system, Dr. Crotty said. It’s capable of producing antibodies and helper T-cells, but not killer T-cells.The modern take on the inactivated virus approach is called a viral vector vaccine.In this strategy, scientists combine elements of the coronavirus with a common cold virus called an adenovirus that won’t make you sick. Since the virus is alive, it can elicit all three kinds of immune responses, Dr. Crotty said.“There are no licensed vaccines right now that use that strategy, but there are all kinds of vaccine trials that have been done around the world with those types [of vaccines] showing that they're straightforward to manufacture. They're very safe,” he said.The University of Oxford is testing a viral vector vaccine for COVID-19 in a Phase 3 clinical trial.Then there are subunit vaccines. These include just a section -- or subunit -- of the virus’ protein.UC San Diego is working on a coronavirus candidate vaccine using this approach.There are subunit vaccines currently on the market for tetanus and other viruses.“Working with proteins is more challenging, just from a laboratory and manufacturing perspective,” Dr. Crotty said.Enter the next phase of vaccine development. Instead of using the virus itself or fragments of it, Inovio Pharmaceuticals is working on a vaccine strategy using just the virus’ genetic information.DNA-based vaccines simply introduce a genetically engineered blueprint of the virus into a person, and the cells do the rest.“Some people get confused about this. They think it’s a genetic vaccine that changes their DNA and becomes part of them, and that’s definitely not the case.” Dr. Crotty said. “They don’t become part of you. Your body chews them up.”Researchers have been working on DNA-based vaccines for about 20 years, Crotty said, but none are currently licensed for use.San Diego-based Arcturus Therapeutics is using an RNA-based approach, along with other companies like Pfizer and Moderna that have entered Phase 3 trials.Messenger RNA reads the DNA instructions and helps translate them into proteins.Dr. Crotty said the DNA and RNA approaches have similar drawbacks and benefits: they’ve never been approved for us, but both can be developed rapidly because they don’t require access to the physical virus.Around the world, there are more than 200 coronavirus vaccines currently in development, according to the Milken Institute. 3459

SAN DIEGO (KGTV) — Light scattered showers fell throughout the day from Mission Valley to Carmel Valley.While Sunday's rainfall marked the first fall rain for the region, Alex Tardy with the National Weather Service said that rain will disappear by Monday. “We're looking at conditions that are bone dry, record dry. It’s never been this dry before and just a little bit of rain like this, while it's nice and we won’t have any fires [Sunday], once the dry air starts blowing through on Monday and continues into Tuesday, it's not going to make much of a difference,” Tardy said.RELATED: In-depth: Why La Ni?a could make wildfire season worseTardy said that San Diego may go long stretches without rainfall this season as we move into a dry La Ni?a winter. However, when the rain eventually comes, it could come in sporadic heavy storms. Tardy also added that the conditions will have fire crews on high alert for weeks. “It also means a delay in the start of our winter so we could be in for a very long fall period where we mostly see dry conditions,” Tardy says. “What that means for us is that fire danger [could be] continuing into the fall and well into the early winter.” 1186

SAN DIEGO (KGTV) - Many local restaurants are having a hard time finding outdoor patio heaters.The difficulty comes as restaurant owners in San Diego County prepare to close their indoor dining areas and take operations outside when new COVID-19 related restrictions take effect Saturday. The county is moving from the state's red to the purple tier following an increase in COVID-19 cases. The purple tier has the toughest COVID-19 related rules.The owners of Sisters Pizza in Hillcrest say they own four outdoor heaters and recently purchased two more from Amazon three weeks ago, one of the last left at the time. They are due to arrive any day."We paid about four times the price of our original space heater," owner Emily Green Lake said. "Right now, the heaters are really what it's all about in keeping people wanting to come back to your spot, or that second glass of wine or that dessert, and all of those extras are what's keeping businesses afloat right now."Premier Patio Heating in Oceanside, which rents out patio heaters, is out. Eddie Essey, vice president of operations, said they have a backlog of about 200 orders from restaurants and hotels. Anyone looking to get some from them now has a six-week wait."I'm saying six weeks," Essey said. "Honestly, that's a little optimistic. Realistically, I don't expect my supply chain to be where I want it to be until March or April."He's putting new orders on a waitlist but advising the customer to keep looking and trying other suppliers."Restaurants are struggling enough as it is that I don't want them to be missing out on income on their patios every night just waiting on me to get a shipment in," he said. "Everyone needs more patio heaters. People that already have some need more, people that don't have any, need some."Many restaurants told ABC 10News off-camera that they could not find any patio heaters and are still looking. Others said they had a difficult time getting their hands on some. 1975
