SAN DIEGO, Calif. (KGTV) - An open letter to the World Health Organization titled “It is Time to Address Airborne Transmission of COVID-19” is signed by 239 scientists from 32 different countries and highlights the importance of acknowledging and protecting the public against the possibility that coronavirus can be spread through the air. One San Diego scientist who signed is from the UCSD Scripps Institution of Oceanography, Doctor Kim Prather.The idea shared is that COVID-19 can be spread from aerosols, which are particles that float in the air rather than dropping to the ground like a droplet. An infected person breathes out aerosols that are suspended in the air, then another person walks through that air and breathes it in.It’s no secret that heath officials have discussed the importance of good airflow to stop the spread, but this paper says leaders like the WHO are not recognizing the possibility that it is airborne and the “lack of clear recommendations on the control measures against the airborne virus will have significant consequences: people may think that they are fully protected by adhering to the current recommendations, but in fact, additional airborne interventions are needed for further reduction of infection risk.”Researchers say wearing masks and social distancing are important steps to stopping the spread, but want to also emphasize that other steps need to be taken to stop the spread through the air. Some steps for public places include getting better ventilation and decreases crowds. At home, people can open doors and windows and also use air purifiers to help. 1618

SAN DIEGO (KGTV)- This Christmas local chefs and volunteers gave the gift of gourmet meals for those in need. It was a two day process. “Just Call Us” Volunteers prepared the food, from scratch, before serving it to the homeless. The volunteers made enough to feed over 400 people. Early this afternoon, the chefs and volunteers delivered the food to three different shelters. The largest being the Alpha Project tent, in Downtown. “We all appreciate it. They all deserve a good meal,” says a staff member with the Alpha Project. Over a dozen volunteers donated their time at the Alpha Project. More volunteers visited Rachel’s Women’s Shelter and San Diego Center for Children. All of the items are donated from Specialty Produce, Cupcakes Squared and Sprouts Farmers Market. Just Call Us Volunteers gives back to those in need year around. They encourage everyone to come spread a little cheer throughout the year. 925

SAN DIEGO, Calif. (KGTV) -- A San Diego couple woke up to find guns pointed in their face inside their own home. The home invasion happened on the 3200 block of Bramson Place just before 7 a.m. on Monday. Officers say the couple was sleeping when they found the suspects inside their home. The suspects were masked and one of them also had a knife. Police say the burglars put the knife to the man's throat, cutting him several times. Neighbors were too afraid to talk on camera but told 10News said they heard all of the commotion. One witness said they saw the two men running towards a nearby parking lot and getting into a red car. Police don't have a suspect description since the suspects were wearing masks. Anyone with information is asked to call the San Diego Police Department at 619-531-2000. 842

SAN DIEGO (KGTV): The San Diego Sheriff's Department has a new tool to help keep deputies safe as they fight the war on drugs.The department just bought 15 TruNarc devices. The hand-held scanners can detect and identify drugs without the deputies having to come into physical contact.Previously, to determine what kind of drug was present at a crime scene, law enforcement would have to scoop a small amount into a kit for testing. The TruNarc uses laser technology to scan through plastic bags.This technology has become increasingly important with the rise of drugs like Fentanyl. Just a microscopic amount can cause an overdose, which has made first responders wary of handling it.The TruNarc can identify more than 200 different drugs and takes less than 2 minutes to complete the scan and give a presumptive result.San Diego Sheriff's Deputies used it earlier this month when they encountered an unconscious man in San Marcos. He was covered in white powder. Deputies called for the scanner and found the powder was Fentanyl. They called for a hazmat team to clean the scene. Officials with the department say the device likely saved the man's life, as he was able to get the medical help he needed. They say it also may have saved the officers, who didn't have to touch the man or the powder until after the scene had been made safe.The devices cost ,400 each. A grant from the Honorary Deputy Sheriff's Association helped pay for them. One has been given to each sub-station around the county. There is also one at every jail and another at the High-Intensity Drug Trafficking Area office. 1617
