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

Despite this closure, it is their hope that they can continue to provide emergency services for their respective communities," officials said.

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
