SAN DIEGO (KGTV) -- While the visible reminders of local wildfires may be gone, San Diego fire officials say what’s left over can still cause a lot of problems especially as the region expects to get rain this weekend.After an intense wildfire happens, the burned vegetation and charred soil forms a water repellant layer that blocks water absorption -- which means the next time it rains, there’s potential for flooding.Cal Fire wants to remind residents to prepare before the rain arrives.Thomas Shoots, a spokesperson for Cal Fire, said, “Anyone near the Valley Fire needs to be prepared for any type of debris or mud flows. They need to have sandbags and the area around their home prepped so that everything looks OK.”In September, the county gave residents free supplies to make sandbags so people could begin their preps for the rainy season.County information on free sandbag availability can be found here.The City of San Diego is also offering sandbags for residents. They’ll be giving them out at select locations on Friday from 1 p.m.-7 p.m., and this weekend from 12 p.m.-2 p.m. Click here for information on city sandbag availability.Anyone who picks up sandbags is asked to wear a mask and have an ID ready. 1230

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) — Tuesday, San Diego County District Attorney Summer Stephan announced two initiatives designed to improve the way law enforcement interacts with people with mental health issues. Up to .5 million will fund the Crisis Intervention and De-escalation Training for police officers and a 911 Mental Health Checklist card. According to Stephan, law enforcement across San Diego County responded to more than 53,000 calls for service that involved a mental health issue last year. A 25-year study of officer-involved shootings in San Diego County shows 79 percent of the incidents included people who had drug and/or mental health issues. And, according to the San Diego Sheriff’s Department, about 30 percent of inmates in San Diego’s jails receive medication for a mental health disorder.Over the past year, 200 stakeholders and experts came up with 30 specific recommendations for how law enforcement and the justice system can better respond to people facing mental health challenges. Crisis and De-escalation Training and development of the 911 Checklist Card are two of the recommendations included in the report.The DA-funded Crisis Intervention and De-escalation Training will consist of a newly-created curriculum that builds upon, and enhances the current training peace officers receive. The training will include classroom discussions led by PERT (Psychiatric Emergency Response Team) experts, role playing "real life" situations, and use of a video simulator known as the MILO Range Theater. Officers will also be trained to recognize the signs of methamphetamine toxicity, a condition often encountered by police. The MILO system is being purchased by the DA’s office using federal asset forfeiture funding. The interactive simulator improves on similar training systems currently available in San Diego County. The training is also portable, so it can travel countywide in order to promote maximum participation by law enforcement while allowing departments to perform their ongoing duties. The DA says the goal of the two initiatives include reducing the need to use deadly force, improve officer safety and reduce the likelihood that the person in the crisis will get injured. 2215

San Diego (KGTV)- After receiving a failing grade by the American Lung Association, the County of San Diego is rolling out some new tools to fight air pollution. In port-side communities like Sherman Heights, Logan Heights and Barrio Logan, the rates for Asthma are the highest in the state. This morning county leaders unveiled its new innovative monitors and cars. “This has never been done before,” says Aclima’s Chief Scientist, Melissa Lunden. For the past three months, two air quality cars have been driven around the county for 24 hours at a time collecting samples of air pollutants. “You get a map, a street by street map, of what the air pollution is and what the air pollutants are on those particular streets,” says Lunden. “That allows you to really locate in that region an area of concern.”Stationary monitors will also be set up in areas like Barrio Logan, Sherman Heights, and Logan Heights. Officials will be able to monitor what’s being inhaled by the people who live in these communities. “What we expect to happen is we’re going to find elevated levels of pollution at the street level that we didn’t see with our regional monitors,” says Assistant Director of the Air Pollution Control District, John Adams. With each monitor, the air is pulled into an inlet over 24 hours. The filter is then taken out and tested in a lab. The Air Pollution Control District has already placed monitors along Interstate 15 in Carmel Mountain and Interstate 5 in San Isidro. The state awarded the county’s Air Pollution Control District .5 million to implement the program. 1589
