SAN DIEGO (KGTV) — As wildfires continue to burn in California, researchers say they may be adding fuel to another emergency: the pandemic.Parts of the Golden State have been buried in a blanket of smoke for weeks. Wildfire smoke is a mixture of many pollutants, but the majority consists of tiny particulate matter called PM2.5, which can also be produced by cars and power plants.“It’s a threat amplifier,” said Dr. Abisola Olulade of Sharp Rees-Stealy Medical Group.In April, researchers at Harvard found that just a small increase in this kind of air pollution led to an 8% jump in the death rate from COVID-19.Studies have shown that air pollution from these tiny particles can increase the risk of death in older adults from other causes, but the Harvard researchers found the increase from COVID-19 was 20 times larger.Why? The most widely accepted theory is that smoke particles, which can burrow deep inside the lungs and enter the bloodstream, can add a layer of health complications for people already fighting the virus.“People that are already fighting off a COVID-19 infection already have compromised heart and lung function if they have severe illness,” Dr. Olulade said. “So that can increase their susceptibility to the effects of wildfires.”The particles can contribute to more inflammation and potentially lead to blood clotting, she said.“Any chink in the armor, so to speak, is going to really make people have trouble maintaining” the body’s stressful fight against the virus, said Dr. Christian Ramers of Family Health Centers of San Diego.Another theory from early COVID-19 research that hasn’t been peer-reviewed: smoke particles could allow the virus to travel farther and survive longer, potentially allowing it to spread to more people. Both Dr. Ramers and Dr. Olulade said there was less research to support this theory.“What makes the sky look hazy when there’s smoke? It’s particles. So it's conceivable, again this is kind of conjecture, but it's conceivable with more particles in the air then yes the virus can latch onto those particles a bit more,” said Dr. Ramers.Doctors say there’s stronger evidence to suggest that wildfire smoke could help the virus enter a healthy person’s body. Not only does smoke wear down the protective lining of our airways, it stimulates certain receptors in the lungs -- the exact receptors that the spike proteins of the coronavirus use to get inside cells.“The virus binds to those ACE2 receptors, so if you have more of them, it can increase the viral load,” said Dr. Olulade.All kinds of air pollution put us at greater risk from respiratory diseases like coronavirus, not just wildfires. But one thing is for sure: Californians have been exposed to a lot of smoke lately.Since the beginning of the year, wildfires in California have burned more than 3 million acres, according to CAL Fire. That’s an area larger than the entire County of San Diego. 2929

SAN DIEGO (KGTV) -- Caltrans Friday unveiled a new study aimed at reducing delays on freeways throughout San Diego County.The study is being held on State Route 78 between Vista Village Drive and Interstate 15.In order to reduce stop-and-go traffic, the study will use seven electronic speed limit signs that will tell drivers the speed that will optimize their commute.“The aim of synchronizing traffic is to gradually slow traffic in advance of a bottleneck in order to keep traffic moving and avoiding stop and go traffic,” said State Route 78 Corridor Director Allan Kosup. “Essentially we are asking motorists to slow down to go faster.”Kosup equated the idea to pouring water into a funnel. Pouring it fast causes it to overflow, while pouring it more slowly gets all the water through efficiently. The signs will display advisory speeds at increments and decrements of 5 miles per hour based on traffic conditions.Drivers expressed skepticism at the program working."Even if I was to go that speed, the other people would be honking their horns behind me," said Michael Ciuzak, who said he tries to avoid the 78 on his commute to San Marcos. Caltrans noted that the speeds are not enforceable, but should help reduce delays. The six-week long study begins on Monday, March 19.Those interested can view real-time results of the study here. The study is being conducted in partnership with the Institute of Transportation Studies at the University of California Berkley. 1513

SAN DIEGO (KGTV) - Could you feed yourself on about per day? The San Diego Hunger Coalition is encouraging San Diegans to take part in the annual CalFresh Challenge to raise awareness about food insecurity. CalFresh public assistance allots .07 daily in food benefits, according to SDHC. The system, known nationally as SNAP, helps those in need but it is insufficient for helping people meet basic needs, SDHC says. During the CalFresh Challenge, participants must spend no more than .35 for five days on all meals, drinks, and snacks. During the week, participants must not accept free food. San Diego Hunger Coalition wants participants to post about the experience on social media with the hashtag #CalFreshChallenge. Participants are also asked to donate to SDHC. 784

SAN DIEGO (KGTV) — As a woman lay paralyzed from a horrific accident, police say someone was inside her car, stealing from her.  The search for that thief is now turning to San Diego County."She was the nicest, most wonderful person I've ever known," said Don Nelson.Nelson says his wife of 27 years, Terri, was on her way to pick up her father for a hospital trip in August when a truck rear-ended her car at a stoplight in Riverside.  As she lay with her neck broken, amid the commotion of bystanders and first responders coming to her aid, police say someone got into her car and stole her purse.Detectives say within days of the accident, surveillance images show her using Terri's credit cards and writing checks in her name. Nelson says as some ,000 worth of purchases were made at various businesses, from fast food restaurants and Albertsons to Costco."I think that's the lowest form of life that could possibly be. You have to be a sorry person to do something like that," said Nelson.For three months, Terri was paralyzed and on a ventilator, until she passed last week from complications from the accident.  Her husband's grief is not the only emotion that consumes him. There is also anger. He's still dealing with collection agencies seeking money from the thief's shopping spree.  During that crime spree, police believe the woman rented a Nissan Rogue in Terri's name, before the CHP pulled that car over on a highway in San Diego County. The two men inside the car have yet to lead detectives to the woman, but police hope tips from the public will."I just can't believe a lightning bolt didn't strike the person. I hope they never run into me, and I know who they are," said Nelson.Nelson believes the rented car was pulled over near downtown San Diego, but the CHP has not confirmed that. If you have any information on the case, call the Riverside Police Department at 951-353-7115. 1936

SAN DIEGO (KGTV) — County law enforcement officials say overdose deaths from fentanyl have sharply increased since last year.The San Diego County District Attorney Office said in the first six months of 2020, there have been 203 fentanyl-related deaths: 119 have been confirmed and 84 are pending confirmation. The victims range in age from 17 to 66 years old.In all of 2019, there were 152 fentanyl-related overdose deaths in the county."This alarming uptick demonstrates that dealers continue cutting various illegal drugs with fentanyl and now more than ever it’s a recipe for death," said District Attorney Summer Stephan. "The public needs to be aware of the danger of using any controlled substance even if packaged like a harmless medicinal pill. Higher overdose numbers tell us there’s likely more product on the street in San Diego that may be laced with deadly fentanyl. I’m urging you to share this potentially life-saving message with your loved ones today."The DA's office says it is prosecuting several cases, including: In January, a 28-year-old smoked a powdery substance given to him by a friend. His mother found him unresponsive in the living room of her home. He was pronounced dead from a fentanyl overdose.In February, a 20-year-old suffering from anxiety, consumed a counterfeit oxycodone pill before going to bed. His roommates found him dead in the morning from a fentanyl overdose.In May, a 19-year-old purchased two Percocets from a friend. He consumed both pills and subsequently died from an overdose. He had fentanyl in his system at the time of his deathFentanyl is a synthetic opioid that is 50 to 100 times more potent than morphine and up to 50 times more potent than heroin, according to officials. Even in doses as little as two milligrams, the drug is lethal for most people. Treating fentanyl overdoses often requires additional naloxone, the drug used to reverse opioid overdoses, to reverse the effects of the drug.Anyone who is need of help with drug addiction can call the San Diego County Access and Crisis Line 888-724-7240 or 2-1-1 San Diego at any time daily. 2113
