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 FRANCISCO (AP) — A calm overnight allowed firefighters to make progress against a trio of massive fires burning in Northern California. But they are girding for the arrival of a weather system Sunday that will bring high winds and thunderstorms that could spark new fires and fan existing blazes that already destroyed nearly 1,000 homes and other structures and forced tens of thousands to evacuate. On Sunday, President Donald Trump said he approved a major disaster declaration for California on Saturday after speaking to California Governor Gavin Newsom."We're working very closely with the governor and very closely with a lot of great state representatives and local representatives. And we'll take care of the situation," Trump said on Sunday. Trump added that the federal government had already deployed over 26,001 first responders, and personnel to battle the wildfires.The fires surrounding the San Francisco Bay Area were started by lightning strikes that were among 12,000 registered in the state in the past week. The National Weather Service issued a “red flag” warning for the area through Monday afternoon, meaning extreme fire conditions exist. 1175

SAN DIEGO (KGTV) -Saturday was the second night five parks were under a new curfew across San Diego. Neighbors were mixed on whether it will affect crime.Police and neighbors celebrated the new curfew Friday at City Heights Square Mini Park. Police said since January 2019 there's been 217 crimes reported within 1,500 feet of the park, ranging from assault to theft.READ RELATED: Neighbors celebrate nightly curfew at San Diego parksRonald Tieken said he spearheaded the initiative, putting together a survey that he said 50 seniors in the building bordering the park responded to. He said the curfew is the first step in turning the tide in the neighborhood.Other neighbors disagree."It's probably going to up the rate of crime in this neighborhood," Ephraim Denmon III said they just need more people who will stand up to crime to fill the park. He said that or hire a security guard."If grown folks are in a grown folks park then they should let grown folks be grown folks," he said arguing the curfew takes away from the neighbors surrounding the park."You have your low income and your seniors, the seniors spend most of their time out here after midnight... Smoking a cigarette, drinking a coffee enjoying life," he said.Tieken said police are on his side, "they have high hopes that they don't have to come every 15 minutes to this park."City Heights Square Mini Park's nightly curfew is from 9 p.m. to 5 a.m. Cedar Ridge Mini Park, Montclair Neighborhood Park, North Park Community Park and North Park Mini Park have a curfew from midnight to 6 a.m. 1566

SAN DIEGO, Calif (KGTV) - In an effort to calm people's fears about new streetlights equipped with cameras and sensors, the City of San Diego will hold a public forum Wednesday night to answer questions and explain what the new technology does, and does not do.The meeting is from 5:30 to 7 pm, at the Malcom X Library on 5148 Market Street.Over the last two years, the city has installed more than 3,000 new streetlights that have "Smart City" technology built into them. The lights have cameras, microphones and sensors to track activity around them throughout the day.RELATED: "Smart" Streetlights coming to San Diego"Pedestrians walking by, cars parking and then leaving, cars traveling by, which direction, how fast," explains Cody Hooven, the City of San Diego's Chief Sustainability Officer.It will also track weather information in real time.That information is turned into meta-data and uploaded to the cloud. According to the city, it can be used for research or to build apps to make life easier. The goal is to turn San Diego into a "Smart City."Examples the city uses describe apps that can tell people when a parking spot opens up, or one that will gauge how many people pass by a certain spot every day.But critics worry about the privacy concerns of having thousands of government-controlled cameras around town.RELATED: Thousands of Streetlights to get "Smart" tech by the end of AugustHooven says the cameras are only used to gather the information. The footage from the cameras isn't accessible to the public, and the cameras are not for surveillance. Also, the footage will only be stored on the camera for 5 days and then deleted.Police may only ask for footage after a crime is committed, and only as part of an investigation. According to the city, the footage has already been used to help SDPD solve a handful of crimes.Hooven also says the cameras will use GPS technology to ensure they only get footage of public spaces, and not areas that are expected to be private. The system uses a process called "curtilage" to blur any areas that shouldn't be shown.Hooven says the city is ready to answer any other questions people have about the new lights at Wednesday's meeting."Technology is coming and we're trying to embrace it to provide a lot of benefits to the city and save us money," she says. "But we need to have these conversations about data privacy to make sure that our citizens and our community is comfortable with how we're using the information."For more details on the "Smart City" program, including an interactive map of where all of the new "Smart" streetlights have already been installed, click here. 2653

SAN FRANCISCO (AP) — A suspect was arrested in a 1970s-era killing in California after investigators used the same advanced DNA testing that helped crack the Golden State Killer case, authorities said Thursday.John Arthur Getreu, 75, was arrested on suspicion of sexually assaulting and strangling 21-year-old Janet Ann Taylor in March 1974, the San Mateo County Sheriff's Office announced.Taylor was last seen alive attempting to hitchhike from Palo Alto to her home in nearby La Honda. Her body was found along a busy street.Getreu was already in custody in Santa Clara County after being charged last year with sexually assaulting and strangling Leslie Perlov, another 21-year-old woman, in 1973.Investigators previously believed the killings of Perlov and Taylor were connected. But their cases had gone unsolved until DNA testing evolved enough to deliver credible results from the degraded DNA collected at both killing scenes.Authorities in both counties submitted DNA samples to the same publicly available DNA database used to identify Joseph DeAngelo, who authorities believe is the Golden State Killer.Getreu was linked to both killings after the testing connected him to both crime scenes, investigators said.In the Golden State Killer case, investigators used DNA from the attacks to locate a relative of DeAngelo then turned to traditional techniques to find the suspect.Authorities have linked the Golden State Killer to 13 attacks of women throughout California between 1974 and 1986."Law enforcement is not giving up on victims," Assistant San Mateo County Sheriff Gregory Rothaus said at a news conference on Getreu in Redwood City. "We have new DNA technology that is a great tool for us."Santa Clara County court records show Getreau is represented by the county's public defender's office, which didn't return a call.Getreau has not yet been appointed a lawyer in San Mateo County. 1910
