SAN DIEGO (KGTV) — With record-breaking temperatures Labor Day weekend, the usual holiday crowd grew larger for San Diego beaches. However, not everyone wanted to join the masses.“But right now it’s so crowded, so crowded and I prefer to avoid that,” said El Cajon resident Celso Patricio.He filled up gallons of water at a water station in East County in preparation. He said the hydration and his air conditioning are how he stays cool in his East County neighborhood.RELATED: Sweltering heat sets several records across San Diego CountyDown the street, Darrin Schallock washed his car at a self-service car wash. He jokingly said the chore is welcomed in the triple-digit heat.“Yeah it’s warm it’s hot, agreed, but that’s why I’m washing my car here, I can wash my car, take a bath, take a shower, save electricity it’s great,” said Schallock.Hot temperatures could break records throughout the holiday weekend. Coastal areas will see highs in the 90s for Saturday and Sunday, and just a few miles inland highs will jump into the 100s, even the mountains. Deserts will be close to 120 for about the third time this summer. A Red Flag Warning will be in effect from 10 a.m. Saturday until 6 p.m. Sunday. It includes inland valleys to the mountains.The heat prompted a state-wide flex alert for the weekend. According to the California Independent System Operator, the flex alert goes into effect Saturday, Sept. 5, and lasts through Monday, Sept. 7. The operator asked customers statewide to conserve energy from 3 p.m. to 9 p.m. 1539

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) — With the increase of online shopping, experts predict that retailers will make a record-breaking number of return transactions this year.December 26 is the official start of the "returns and exchanges" season.Grab a cart. It's back to the store. David Warren's sofa just didn't look right. So he was back at the Target store in Kearny Mesa Saturday afternoon."I'm just returning these pillows and shirts," Warren said. "I'm going to swap them out for something smaller."Fernando Delacruz and his wife bought themselves bicycles to kick start a healthy New Year's resolution."I figured I'm going to need a bike so I can exercise," Delacruz said. "And then my wife said, 'Oh that's a cool Christmas gift for me too!'"The couple bought their bikes at target.com. Delacruz's fit perfectly, but his wife's did not."When she tried it on, it was kind of a little big for her," Delacruz said. "So we have to return it."The pandemic has caused a surge in online shoppers, a saving grace for retailers. But not being able to touch and feel the products means there have been a record-setting number of returns. Experts say returns will cost companies more than billion this holiday season. But retailers have managed to make the return process much easier, many places not even requiring receipts."We do have a Target card, and they can trace it from there, so we didn't have to worry about that," Delacruz said.Delacruz says now they are at the store to return what didn't fit and replace it with one that does."We're probably going to look for another bike today," Delacruz said.According to the 2020 Deloitte Holiday Retail Survey, 45% of shoppers prefer the "buy online, return in-store or curbside" service. 1732
