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) - Two researchers, including one from the Scripps Institution of Oceanography at UC San Diego, are in Antarctica in an effort to uncover the planet's oldest ice.The research trip is part of a cordial international race to find the ice, which will give geologists and climate scientists new insight into Earth's climate history. Scripps paleoclimatologist Jeff Severinghaus and University of Minnesota-Deluth geologist John Goodge arrived this month at an ice-drilling outpost at McMurdo Station, Antarctica.In October, Severinghaus and researchers at Princeton University published a study in the journal Nature analyzing a two-million-year-old ice core. However, that core was incomplete in its historical portrait of ancient air. According to Severinghaus' ice dating lab, the planet's oldest ice is roughly 2.7 million years old.RELATED: San Diego Zoo welcomes second rhino born via artificial inseminationSeaWorld frees whale tangled in 900 feet of rope off La JollaSan Diegans can fly over rush-hour traffic with FLOAT air service"That core ... was all broken up," Severinghaus said of the Princeton study. "It's like in archaeology when you find pieces of broken pottery you're trying to put back together."The two researchers are attempting to expedite the conventional ice drilling process, which currently takes roughly five years to dig two miles to the Antarctic ice shelf's deepest point. They believe their 50-ton drill could secure a 50-meter ice core with a full timeline of the continent's geologic development. Eventually, it could be used to dig to the continent's bedrock, which dates back 3 billion years.In addition to each other, geologists and climate scientists in the southern hemisphere are in a race against nature, as climate change continues to melt Antarctic ice and cause sea levels to rise, particularly on the continent's western edge, according to Goodge."The bigger question is what's happening in East Antarctica because there's a lot more sea level rise potential if it begins to melt as well," he said. "So we really need to understand what those conditions are."Once collected, the researchers will pack the ice samples in boxes until January, when the Antarctic sea ice thaws and the samples can be shipped to Port Hueneme in Ventura County. They will then be transported to the National Science Foundation's Ice Core Facility in Lakewood, Colorado, for study in late spring. 2439

SAN DIEGO (CNS) - The San Diego Zoo and Zoo Safari Park combined for a record attendance of more than 5.5 million visitors in 2018, it was announced today.More than 4 million people visited the zoo in 2018 and over 1.5 million visited the Safari Park. It was the first year in the zoo's 100-year history in which attendance surpassed 4 million, according to zoo officials, who believe the appeal of new exhibits such as Walkabout Australia and Conrad Prebys Africa Rocks contributed significantly to the record-setting year."We are delighted to have been able to host more than four million people at the zoo, and I know that a lot of this is due to the wonderful new guest areas and the commitment to guest service shown by our employees every day," said San Diego Zoo Director Dwight Scott. "It has been a pleasure to share our love of wildlife with so many people this year -- and we know that this high attendance will help to fund additional conservation work in the future."Zoo officials also touted the year's conservation efforts of San Diego Zoo Global, the nonprofit that runs the zoo and the Safari Park. The organization was able to continue increasing its work conserving and protecting at-risk species all over the world due, in part, to the record attendance numbers."This attendance record shows us that people care about wildlife, and care about saving species," said Douglas G. Myers, president and CEO of San Diego Zoo Global. "This last year, we increased communications about the need to save species and ran advertising asking people to support our efforts by coming to the zoo and the Safari Park. More than five and a half million people responded by visiting us in 2018 -- imagine what we can do to save species next year!" 1757

SAN DIEGO (KGTV) — City leaders say they're making strides in overhauling its water department after a disastrous 2018. In a presentation to the Audit Committee Wednesday, city public utilities managers said they had implemented about a dozen reforms after a series of missteps last year. In 2018, thousands of San Diegans received erroneous water bills, which an audit largely blamed on human error. A later audit found that some meter box and lid replacement workers were fudging time cards amid a 22,000 unit backlog. RELATED: New round of complaints on high water bills"We needed to change the culture and make sure that all these issues were addressed," said Johnnie Perkins, San Diego's deputy chief operating officer. Perkins said the Public Utilities Department has implemented new, efficient work strategies. These include getting workers out to the field faster, overhauling how customer service representatives interact with residents, and using software to pick routes that make sense. Previously, for example, workers could be sent to do water meter work in Rancho Bernardo only to be sent to San Ysidro. The city auditor is currently monitoring the progress.RELATED: Audit shows City sent thousands of faulty water billsBut Rodney Fowler Sr., who heads the union that represents meter replacement workers, said the changes aren't addressing obvious issues: The department is understaffed, and the vehicle fleet is unreliable. "They're 10 years old," said Fowler Sr., president of AFSCME, AFL-CIO Local 127. "A private contractor would never use a service vehicle 10 years because it starts to cost them money."Perkins said the city could contract out for workers to address the backlog, and is currently assessing investments in new equipment.RELATED: City to begin building alternative to SDG&ECity Councilman Scott Sherman, who chairs the audit committee, said the issue is not as simple as staffing and equipment. "It needs to be a give and take," he said. "We need to do some of those things that the unions want to do, and they need to do some of the things that we want to do." 2107
