SAN DIEGO (CNS) - The San Diego Unified School District has started voluntary COVID-19 testing for students and staff at several elementary schools, under a partnership with UC San Diego Health, it was announced Tuesday.The testing initiative is designed to help to keep students and staff safe while expanding in-person learning amid the pandemic. The reopening strategy was developed in collaboration with UCSD infectious disease experts, according to SDUSD Superintendent Cindy Marten."The end of the COVID-19 crisis is now in sight with the development and delivery of a safe and effective vaccine, and that has given us all cause to hope," Marten said. "In the meantime, we are doing everything we can to continue operating safely despite the worsening infection rates in our community. That is why testing is essential."San Diego Unified's testing plan was announced in November, and the Board of Education voted then to authorize an initial million investment in the testing plan, which includes a joint laboratory services testing agreement with UCSD Medical Center. The board will consider ratifying that agreement Tuesday.Eventually, the testing program could be expanded to include all 100,000 students within the district and its more than 10,000 staff members."Scientific models from our colleagues at UC San Diego show we can prevent 90% of all transmissions on campus with effective testing every two weeks," Marten said. "That level of protection will not only help us reopen schools; it will help us keep them open, and avoid the back-and-forth, open-and- shut problems that have plagued other school systems."Free COVID-19 tests will be available to students and staff at 10 district campuses this week -- Rosa Parks, Penn, Foster, Gage, Mason, Vista Grande, Dingman, Jerabek, Hearst and Benchley Weinberger elementary schools -- with additional testing to be offered from Jan. 4-15.The goal is to test every student and staff member every two weeks, starting with those on campus for the first phase of school reopening."The implementation of COVID-19 testing is an important tool for district campuses in identifying and limiting the spread of the coronavirus," district physician Dr. Howard Taras said. "Although voluntary, I strongly urge student and staff participation in the testing program for their health and the health of others."The campuses were selected based on generally higher local case rates of community infections, combined with student and staff participation rates in appointment-based learning.The tests will be administered in campus auditoriums and multi-purpose rooms by medical professionals from UCSD Health in conjunction with staff members from the district's health office. The procedure, which takes about 15 seconds, involves swabbing both nostrils. The swab itself is inserted roughly the same distance as a common nasal spray applicator."The science is clear when it comes to the importance of COVID-19 testing, even if a person has no symptoms," said Patty Maysent, CEO of UC San Diego Health. "It is a critical component in slowing and containing the spread of COVID-19, along with measures like masking, social distancing and proper hand hygiene. Swabbing a mouth or a nose is quick and easy. And it can ultimately help save lives."Test results will be available about 24 hours following the test. Individuals who test positive will receive a phone call from a UCSD health professional and follow-up from district nursing staff. Results will be be accessed through UC San Diego My Chart, https://myucsdchart.ucsd.edu/ucsd/Authentication/Login?.Students and staff members who test negative may get retested every two weeks. Those who test positive for COVID-19 will not be re-tested for 90 days."Even after the vaccine rolls out this winter, I anticipate that testing will remain an important tool for schools," Taras said. "I do not anticipate that school-age children will be offered the vaccine for many months after the vaccine is available to adults."There is very little research on the effectiveness of this vaccine on children under 12. And while we are hopeful that it will be just as effective in younger age groups as it is in adults, vigilance about reducing the numbers of potentially positive and infectious children on our campuses via testing will remain an important precaution for many months after staff members are vaccinated," he said. 4423

SAN DIEGO (CNS) - UCSD and Scripps Institution of Oceanography alumna Megan McArthur will head to space as the pilot for the SpaceX Crew-2 mission in early 2021, NASA announced this week.The Crew-2 flight will be the second SpaceX Crew Dragon flight to the International Space Station as part of NASA's commercial crew program.McArthur, who received her doctorate in oceanography from Scripps in 2002, traveled to space aboard the space shuttle Atlantis in 2009. She and her crew were part of a 12-day mission to repair the Hubble Space Telescope. McArthur operated the shuttle's robotic arm that grabbed and released the telescope, making her the last person to "touch" the telescope. She was born in Honolulu but considers California her home state. She holds a bachelor's degree in engineering from UCLA.The SpaceX Crew-2 flight will be her first trip to the International Space Station.Joining McArthur is NASA astronaut Shane Kimbrough as mission commander with Japan Aerospace Exploration Agency astronaut Akihiko Hoshide and European Space Agency astronaut Thomas Pesquet as mission specialists.McArthur is one of two Scripps Oceanography alumni who are astronauts. Alumna Jessica Meir returned from a visit to the International Space Station in April. Astronaut Kate Rubins also graduated from UC San Diego with a degree in biological sciences.Crew-2 is targeted to launch in spring 2021, following the successful completion of both NASA's SpaceX Demo-2 test flight mission -- which is expected to return to Earth on Sunday -- and the launch of NASA's SpaceX Crew-1 mission -- which is targeted for late September. The Crew-2 astronauts will remain aboard the space station for approximately six months as expedition crew members, along with three crewmates who will launch via a Russian Soyuz spacecraft. The increase of the full space station crew complement to seven members will allow NASA to effectively double the amount of science that can be conducted in space.NASA's commercial crew program is working with the American aerospace industry as companies develop and operate a new generation of spacecraft and launch systems capable of carrying crews to low-Earth orbit and the space station. A NASA statement said commercial transportation to and from the station will provide expanded utility, additional research time and broader opportunities for discovery on the orbital outpost. 2406

SAN DIEGO (KGTV) -- A colorful moment for four San Diegans today. They've been color blind their whole lives, but thanks to a new pair of special glasses...that's about to change."Eventually when I got to high school, and realizing I was color blind was one of those things, like, oh, that's why I couldn't see that or I couldn't see that," said Ricardo Solano. Solano is one of about 300 million people around the world who are color blind.But as a research associate for a biotech company, there are days when he needs a little help from his colleagues."One of the main dyes they use is like red and green to differentiate things," he said, laughing. "It's a big contrast apparently, but I can't see the contrast."Solano has a good sense of humor about it, but that doesn't mean that he doesn't wish he could see the full elegance of a San Diego sunset."Just enjoying the beauty of life," he said. "I like to go backpacking and outdoors and stuff."For people who are color blind, pink looks gray, red looks brown and the colors red and green can look almost white-ish."Color vision deficiency is passed down through the father's genes," said Corey Ulz, an optician at Scripps Poway Eyecare. He said things can look dull and colors, washed out."It basically makes the colors that you and I would normally see normally not as vibrant," he said. "A little more muddled."On Monday, Solano and three other San Diegans got to see vibrant color, thanks to a special pair of enchroma glasses.Their reactions and expressions were heartwarming. "Red. I feel like a little kid right now haha," Solano said, smiling. The pair of glasses do more than make the world a little brighter. Solano hopes they'll make work easier, too. 1760

SAN DIEGO (KGTV) — A group of good Samaritans is receiving praise after knocking down a brush fire in Carmel Valley on Tuesday afternoon.After spending all day on top of a roof, Ubaldo Lopez and his team at Palomar Solar & Roofing were on their way back to the office."We were going down the hill, and it started to smell," Lopez said. "At first, I thought somebody crashed, but then I saw the fire."Many people slowed down on Carmel Valley Road as the flames crept closer. Others called 911 for help. But before the firefighters arrived, Lopez and his team pulled over and jumped into action."I got the extinguisher and a couple of my buddies here, they got the shovels and started putting dirt on it," Lopez pointed at his team. Right beside him attacking the growing flames were his son Damien and co-workers, Cirinio Rios and Miguel Esteban.Although the men are not trained firefighters, they are familiar with fire. They work on what is called "torch down roofing," a process where a flame is used to melt a rubbery membrane on a flat roof to make it waterproof. So they know the dangers of what could happen if the winds picked up."The weather was crazy and the red flag [warning]," Lopez said. "The fire department, they've been so busy, so you know, that could have gone out of hand."With the help of a few other good Samaritans, the team stopped the fire from spreading. Minutes later, they drove off, without knowing they would be praised for their swift actions all over social media."Omg that would have been really tragic had it spread," one person wrote on Facebook."Wow. Great effort. And saved the day," said another.When asked about being called heroes, Lopez humbly laughed."Oh no, no, no," he said. "We were just lucky that we were passing by. We got to help each other." 1802
