SAN DIEGO (KGTV) People across California will soon be able to use an app to notify or find out if they have been exposed to COVID-19.The CA Notify system was launched on the campus of UC San Diego in September. Monday, Governor Gavin Newsom announced the tool would be available on Google and Apple devices statewide beginning on December 10th.Dr. Christopher Longhurst, Chief Information Officer for UC San Diego Health, says the tool helps stop the spread of the virus on campus."While San Diego case rates have surged from 3 to 6 percent, our campus has fortunately remained a safer place with our students and employees testing positive at less than 1 percent," said Dr. Longhurst.Philip Tajanko is a freshman at UCSD. He signed up for the app shortly after arriving on campus in September."I figured that I might as well download the app just in case," said Tajanko.Tajanko tested positive for the virus in October."Outside of the people I directly informed by giving them a phone call or text, it did give me some peace of mind knowing that I could just send out this blanket alert that would notify anyone that I had been in contact with but don't have their phone number," said Tajanko.The system uses smartphone technology when a users' phone is within close proximity to another user for an extended period."You're not going to get an exposure unless your phone is within 6 feet of someone else's device for greater than 15 minutes cumulatively," said Dr. Longhurst.The governor stressed the app is opt-in, 100% private, secure, and does not track location.It has been effective. Even if we don't have tens of millions of people participating in this program, the more people who opt-in, the more effective it can be," said Governor Newsom. 1759

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)- Parents at several San Diego County high schools have been notified that students could have been exposed to Pertussis, also known as whooping cough. Carlsbad High School confirmed two cases last week. Monday, parents at Mt. Carmel High School were notified that students at that school may have been exposed to the infection, though it wasn't clear how many confirmed cases there have been at the school. “This is probably the most contagious bacterial disease,” says Eric McDonald, with the county’s Health and Human Services Department. “For every one person who has it, when they expose people who have not had or been immunized, they can infect up to 16 or 17 other people.”McDonald says symptoms of a typical cold are a runny nose, low-grade fever, and a cough. For someone who may have pertussis “its the persistence of the cough that should be the number one clue.”So far this year, in San Diego County, there have been over 70 confirmed cases of pertussis. “The number of cases in San Diego are higher than most of California, particularly for infants under the age of four months.”If your child has a cough that lasts almost two weeks, they should be treated by a doctor. McDonald recommends everyone get the DTaP shot to lower the risk of getting pertussis, especially pregnant women in their third trimester. 1347

SAN FRANCISCO — Verizon is joining an escalating movement to siphon advertising away from Facebook in an effort to pressure the company into doing more to prevent racist and violent information from being shared on its social networking service.The decision announced Thursday by one of the world's biggest telecommunications companies is part of a boycott organized by civil rights and other advocacy groups under the rallying cry of "#StopHateforProfit."The NAACP and the ADL are among the organizations behind the movement.The protest was spurred by last month's killing of George Floyd by Minneapolis police.Facebook says it is in talks with the boycott organizers in an effort to become a "force for good."Verizon is by far the largest company to join the movement. Other companies who have agreed to at least temporarily suspend ad buys on Facebook and Instagram are The North Face, Patagonia, REI and Ben & Jerry's. 934
