SAN DIEGO (KGTV) – With Thanksgiving just days away, local health officials are seeing long lines at San Diego County COVID-19 test sites with many San Diegans hoping to get tested before the holiday.With the sudden surge of testing, some experts, such as UC San Diego Chief of Infectious Diseases Dr. Davey Smith, warn that getting a test is not enough to minimize the risk of spreading the coronavirus.“There’s a worrisome reason that people are planning to go visit their older relatives and they think they’re going to be 100 percent safe,” Smith said.Smith also said getting a test now could still give out a false negative result.“If I get tested now, it doesn't mean that I'm not infected, it just means that I'm not actively shedding the virus,” Smith told ABC 10News.On Monday, at San Diego International Airport, ABC 10News spoke to travelers who had the same thought.“I got tested about a week ago, just to make sure that everything is OK. And I know you can have it without having symptoms, so I did as much as I could to prepare before I came,” said Dana McLin.And along with getting a test, these travelers made sure they brought everything else they need to stay health while traveling this Thanksgiving holiday.Jan McLin said, “We are wearing our masks and we use hand sanitizers, sanitizing wipes, washing out hands constantly. This is necessary travel; when it’s necessary, you have to do everything not only for yourself but everyone around you as well.” 1481

SAN DIEGO (KGTV) -- We’ve known for a while that COVID-19 hits people over 65 especially hard, but a study published Wednesday from researchers in San Diego offers new insight into why that happens.The numbers are staggering: if you’re 65 or older, your risk of winding up in the hospital from COVID-19 is five to 11 times higher than someone under 30. Your risk of death is at least 90 times higher, according to data from the Centers for Disease Control and Prevention.Researchers at the La Jolla Institute for Immunology say the reason why older people fare so much worse appears to be from a lack of T-cells, a type of white blood cell that can decline with age.“Some viruses get controlled by one part of the immune system. Some viruses get controlled by another. In this case it seems that T-cells really do a lot of the work,” said Dr. Shane Crotty, one of the authors of the study published Wednesday in the journal Cell.Dr. Crotty and his colleagues looked at 50 people infected with the virus, and they measured the three elements of the adaptive immune system in detail: antibodies, helper T-cells and killer T-cells.Then they compared the measurements to how people fared against the virus. Some patients in the study group had severe cases, others had mild infections.The researchers found that people with all three branches of the adaptive immune system tended to fully recover. People with severe cases of the virus often lacked one or more of the immune branches, and it was particularly evident in older people.“Our data indicated that of the older individuals, it was particularly the ones that had fewer T-cells to start that look like they really struggled to control this virus,” Dr. Crotty said.As we age, we have fewer T-cells to send after invading pathogens. “That collection of T-cells gets smaller. So it’s harder to recognize a new virus,” Crotty said.Among the 748 deaths in San Diego County reported as of Wednesday, 87% were people aged 60 and older.The findings from LJI may have implications in the search for a vaccine against COVID-19. The data suggests that vaccine-makers may want to target a drug that elicits all three branches of the immune response, Dr. Crotty said. Some vaccine approaches, such as inactivated virus vaccines, only elicit two of three branches, not killer T-cells. However, Crotty said it was too soon to rule any candidates. Two strong branches produced by a vaccine could potentially cover for the lack of a third, he said.Crotty said the findings could help vaccine-makers interpret results from the clinical trials and find the right dosing.“Is a given vaccine a good vaccine, and you just need a booster immunization?” he said. “Does it work well in one population but it doesn’t help in the elderly because it doesn’t generate a T-cell response, for example? Those are the scenarios when this type of knowledge will come into play.” 2906

SAN DIEGO (KGTV) -- Two people are dead after a car and semi-truck collided during a Border Patrol pursuit in Otay Mesa Tuesday night, agents say. According to Border Patrol, two people were seen crossing over the border into the United States early Tuesday night. Agents described them as a man and a woman.The agency told 10News a getaway car was waiting for the pair. The driver of the car led agents on a high-speed chase reaching speeds of more than 100 miles per hour. RELATED: Three hospitalized after Border Patrol chase leads to crash in CampoThe pursuit lasted for about a quarter of a mile before the driver reportedly lost control and crashed into the back of a semi-truck, forcing the car beneath the truck and into a ditch. Two of the men inside the vehicle died while the woman was taken to the hospital and, as of Tuesday night, was listed in critical condition. The identity of the victims hasn’t been released. 937
