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)- After a rise in COVID- 19 cases, the governor closed many indoor activities, including places of worship. Churches around the county were forced to make changes to their services, but some embrace the new scenery.Sunday morning mass was held outdoors for parishioners at Saint Agnes Catholic Church. Members brought their beach chairs to worship in the church’s parking lot.“I love being able to see people here, gathered together, and worship together,” says Father Bill Marquis.The changes came after the governor’s announcement to stop indoor activities due to the rise in COVID-19 cases across the state. San Diego county is one a few dozen on the state’s watchlist.Saint Agnes Catholic Church says it is still offering virtual services, but it was the members who requested to have the “beach chair mass” on Sunday morning.“Parishioners asked me if we were going to have mass on Sunday, I said we were going to live stream it,” says Father Marquis. “She says we would still like to have an outdoor mass on Sunday, if possible. I said why, and she said because we want to receive communion. That was the deciding factor for me.”As many churches around the county make changes to their services, some places of worship are working with city leaders to hold outdoor services. Poway officials approved a plan to share park space with places of worship and fitness centers. The City of El Cajon is looking into a similar idea. 1452

SAN DIEGO (KGTV)- Across San Diego County, most law enforcement agencies have been focusing on education rather than enforcement regarding violations of the county’s public health order.The goal is to get people to comply voluntarily.“What we’re trying to do here is educate the public so that ultimately we can save lives,” said San Diego Sheriff, Bill Gore.In the City of Coronado, police have been offering people free facial coverings.“To approach folks in an enforcement posture, I’m not sure we’re going to get the type of compliance we need,” said Coronado Police Chief Chuck Kaye. “When we see folks that are not using face coverings we say ‘hey can we offer you a face covering?’”This Fourth of July weekend is expected to be busy, especially at local beaches.California Gov. Gavin Newsom ordered all parking lots of state beaches in Southern California and the Bay Area to be closed for the weekend.The City of Oceanside has also decided to close off its beach parking lots.So far, no community COVID-19 outbreaks have been linked to outdoor settings.“I spoke to a number of the coastal mayors and said ‘are you confident you can enforce the physical distancing at your beaches?’” said county’s supervisor, Nathan Fletcher. “They said they can so we have to trust them that they can do that as we move forward into the weekend,” said San Diego County supervisor Nathan Fletcher.“We have our normal patrols in our coastal towns that we police for,” said Gore. “We’re not planning to add enforcement details to be specifically walking on the beaches to look at who’s wearing a mask, who’s socially distanced or not.”Gore said he expects beachgoers to comply with social distancing and facial covering rules when required.Under the latest public health order, restaurants must close to the public from 10 PM TO 5 AM.Bars, wineries, and breweries that don’t serve food must completely close down. Wineries that operate outside are an exception and may stay open.“State regulatory teams will be in different regions, we’ll be working with that team here which part of it is Alcohol Beverage Control and our county regulatory agency,” said Gore. “So, we can do enforcement if we don’t get that voluntary compliance that we’re seeking,” said Gore.The San Diego Police Department said it's anticipating crowds this weekend and will have extra officers patroling the beaches and bays to keep people safe. If officers witness violations of the public health order, they will educate people to seek compliance. 2517

SAN DIEGO (KGTV) — While the Friday night lights of high school football are dimmed for the time being, the same cannot be said for the pickleball courts in Del Cerro."There is nothing better than to play pickleball on a Friday night," says avid player Deanna McDonald.Some players decided to pick up the game after the pandemic hit, and found it to be so much fun. And while some sports and other physical activities have been limited, or put on hold due to COVID-19, pickleball has become a great alternative."When my gym closed, I was looking for something to do besides just walking around my neighborhood a few times, and get some exercise," says pickleball newcomer Noli Zosa.As for player Joe Arnold, he can't get enough pickleball."I suffer from what is called pickleball addictive disorder, and it really helps that a lot," Arnold joked.Prior to the pandemic, pickleball was exploding in popularity. From the young to the old, it's a sport that can be played at any age."The people who play are so nice, and you'll hear a lot of laughter in all the games," says Zosa.Now, when it comes to playing pickleball, there are no actual COVID rules, but these players do their best to keep the game as safe as possible."We sanitize the ball, and try to keep our social distance after each game. We just try to be smart." 1329

SAN DIEGO (KGTV) — With San Diego County back in the purple tier, religious gatherings have to move back outdoors.The first Sunday back in California’s most restrictive tier and Rock Church held five outdoor services around the county, but this is not new for them. The megachurch moved to live streaming of services at the beginning of the pandemic, then added in outdoor services about six weeks ago.In the red tier, religious services could hold indoor services at 25% capacity or 100 people, whichever was fewer. Point Loma’s Pastor Travis Gibson said during this time, they had the option to move outdoors, but with 7,000 people attending Point Loma’s services alone, it wasn’t worth it.“One hundred people is not even the volunteers so this is the best option,” he said, standing outside after an outdoor service.RELATED: San Diego houses of worship told to move services outside by SaturdayHe said they have anywhere from 50,000 to 75,000 people watching their live streamed services every week, with only about 1,000 people coming to this new outside setup, but they’re happy to be able to give different worship options to their members.“There are so many ways to worship God. Four walls are great. You can control the temperature, you can control the airplanes, you can control the lights, but you don’t need it to worship God,” said Pastor Travis.He said they do not have plans to try to move back inside anytime soon because they don’t want to switch back and forth, so they’re moving slowly and making sure the online and outside services work.RELATED: San Diego County health officials warn local churches about holding indoor servicesNot every church has been as flexible. This is the second time churches were asked to move outside. The first time churches were banned from indoor services in July, at least three San Diego churches were either sent warning letters or cease and desist letters because they refused to move outdoors. ABC 10News is waiting to hear if any churches violated the county orders during this second rollback. 2058
