SAN YSIDRO, Calif. (KGTV) -- San Diego Fire-Rescue is on scene of a brush fire burning in San Ysidro Monday afternoon. According to department spokeswoman Mónica Mu?oz, the fire sparked near State Route 905 west and Caliente Avenue in an area near San Ysidro High School. The fire burned about one and a half acres before the forward rate of spread was stopped. No structures were threatened and no one was injured, according to Mu?oz.Three San Diego Fire-Rescue engines and two federal fire brush engines and a helicopter team responded to the blaze.

Scientists at the University of Nevada, Reno School of Medicine (UNR Med), led by its Nevada State Public Health Laboratory (NSPHL) are studying a likely case of COVID-19 reinfection.Forty-eight days after testing positive for SARS-CoV-2 in April 2020 and after testing negative consecutively twice, a Washoe County, Nevada patient tested positive again, in June.The patient had tested negative on two separate occasions in the interim. The genomes of the patient’s virus samples were sequenced in April and June, displaying significant genetic discordance between the two cases, implying the patient was infected twice.“We examined the genomic material of the viruses and samples to investigate this, says NSPHL Director Mark Pandori. “It is just one finding, but it shows that a person can possibly become infected with SARS-CoV-2 a second time.”To solidify confidence in the case, Pandori and the research team partnered with the Washoe County Sheriff’s Office Biology Unit to conduct identity testing on the specimens and lab samples evaluated in the study to verify the specimens were from the same person.Embedded in the genomic material of SARS-CoV-2 is a detailed code that Pandori says may provide insight to a better understanding of this virus.“A virus has a biological genome like all living things. Since March, the NSPHL has analyzed the genomic RNA of approximately 200 positive COVID-19 samples from Nevadans who have tested positive for COVID-19,” said Pandori. “The power of genomic information could turn the tables in the fight against the coronavirus.” The information is shared to a world-wide database known as “GISAID”,” alongside the work of thousands of researchers.According to Pandori and the NSPHL-led research team, reinfection cases are a potential warning sign that it is possible to catch COVID-19 more than once, and with unpredictable severity.“If reinfection is possible on such a short timeline, there may be implications for the efficacy of vaccines developed to fight the disease. It may also have implications for herd immunity,” says Pandori. “It is important to note, that this is a singular finding. It does not provide any information to us with regard to the generalizability of this phenomenon.”Herd immunity depends on the theory that after natural infection, our immune systems will collectively protect us as a community from reinfection and further spread. There are currently many more unknowns than knowns about immune responses to COVID-19. “After one recover from COVID-19, we still do not know how much immunity is built up, how long it may last, or how well antibodies play a role in protection against reinfection,” says Pandori.”While research and scientific advancements continue to build, Pandori says the hard work of fighting this pandemic together will continue through the use of facial coverings, hand-washing, social distancing, as well as wide-scale testing, contact tracing, and isolation of new cases.“This is a novel disease. We still have a steep learning curve ahead and lots of work to do, especially as inconvenient truths arise,” says Pandori.The NSPHL team are publishing their COVID-19 reinfection findings. Their report is publicly accessible on the SSRN preprint server, at https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3681489. This story was first reported by KTNV in Las Vegas, Nevada. 3384

SAN FRANCISCO (AP) — She was a self-described "adrenaline junkie," and he took "wow-worthy photos" of the couple posing at the edge of cliffs and jumping from planes that appeared on social media and a travel blog that attracted thousands of followers.In one post at the Grand Canyon this spring, 30-year-old Meenakshi Moorthy even warned daredevils who try to snap selfies from dangerous heights: "Did you know that wind gusts can be FATAL???" The caption accompanies a photo of Moorthy sitting on the edge of the canyon's North Rim.The couple's latest trip turned out to be their last. Moorthy and her husband, Vishnu Viswanath, 29, who were Indian expats living in California, fell to their deaths in Yosemite National Park last week while taking a selfie, the man's brother said Tuesday.RELATED: Brother: Indian tourists died in Yosemite fall while taking a selfieThey set up their tripod near a ledge at a scenic overlook in the California park, Viswanath's brother, Jishnu Viswanath, told The Associated Press. Visitors saw the camera the next morning and alerted park rangers, who "used high-powered binoculars to find them and used helicopters to airlift the bodies," he said.Rangers found their bodies about 800 feet (245 meters) below Taft Point, where visitors can walk to the edge of a vertigo-inducing granite ledge that offers spectacular views of the Yosemite Valley below.Their thrill-seeking social media posts foreshadow the couple's link to the growing problem of selfie deaths.RELATED: 2 die after falling from?overlook?in Yosemite National ParkA study published this month in the Journal of Family Medicine and Primary Care said 259 people had died taking selfies between October 2011 and November 2017.The report, based on findings from researchers in India who scoured worldwide media reports, said the main causes of selfie deaths were drowning, usually involving people being washed away by waves or falling from a boat, followed by people killed while posing in front of a moving train, deaths involving falls from high places or while taking pictures with dangerous animals.More than 10 people have died at Yosemite this year, some from natural causes and others from falls, park spokesman Scott Gediman said.RELATED: Photographer finds mystery engagement couple in viral Yosemite photoMoorthy and Viswanath were born in India and had lived in the United States for a few years, most recently in the San Francisco Bay Area.

She said Moorthy and Viswanath were both good students who were fond of traveling and had married at a Hindu temple in Kerala in southern India four years ago.Moorthy described her and her husband as "travel obsessed" on their blog, "Holidays & Happily Ever Afters," which was taken down Tuesday. It was filled with photos of the couple in front of snowy peaks and on romantic trips across Europe, where they took selfies from a gondola in Venice, at the Leaning Tower of Pisa and at the Vatican.RELATED: More than 250 people around the world have died taking selfies since 2011Moorthy wanted to work full time as a travel blogger, her brother-in-law said. She described herself as a "quirky free spirit" and "an ardent adrenaline junkie — roller coasters and skydiving does not scare me," Viswanath said.She posed at the edge of the Grand Canyon wearing a Wonder Woman costume, writing, "A lot of us including yours truly is a fan of daredevilry attempts of standing at the edge of cliffs — and skyscrapers. But did you know that wind gust can be FATAL??? Is our life just worth one photo?"Her husband's Facebook cover photo shows the couple smiling, with arms around each other standing at a Grand Canyon precipice. "Living life on the edge," he wrote.RELATED: Teen dies after falling while taking?selfie?in Yosemite National ParkIn a post from July 2017, the couple celebrated their wedding anniversary by skydiving in Santa Barbara, California. Moorthy posted a video on Instagram that shows her in a T-shirt saying, "Gimme Danger," and flashing a thumbs-up as she jumps from the plane."I believe I can flyyy. I believe i can touch the skyyy," she wrote in the post. "Aaaand touch the sky I did from an effin' 18000 feet thanks to the unconditional love-ninja in my life, Vishnu, who literally took this year's anniversary surprise a notch 'higher' than last year's hot air ballooning adventure, by gifting this adrenaline junkie with one of the highest tandem skydives in the world!"She also blogged about depression. In a post from April, Moorthy apologized to readers for going silent and "disappearing for more than a year."RELATED: UCSD graduate dies after fall at Yosemite"Between battling the tightening tentacles of depression and blustering in the tempest of moving madness, I am afraid social media is taking a back seat??" she wrote.The couple's pictures indicated they liked to pose in scenic spots at sunset, which was the last time they were seen alive.In an eerie coincidence, another couple who hiked to Taft Point captured pictures of Moorthy prior to her fall, saying she appears in the background of two of their selfies.Sean Matteson said Moorthy stood out from the crowd enjoying sunset at the overlook because her hair was dyed bright pink. He said she made him a little nervous because she was close to the edge.RELATED: Hiker falls to his death during thunderstorm at Yosemite"She was very close to the edge, but it looked like she was enjoying herself," said Matteson of Oakland, California. "She gave me the willies. There aren't any railings. I was not about to get that close to the edge. But she seemed comfortable. She didn't seem like she was in distress or anything."The travel advice website MyYosemitePark.com posted a photo of Taft Point to illustrate its "bad selfies" list, warning tourists: "Don't pose on top of a huge granite drop-off." It added, "It would only take a loose rock or bad footing to plummet."Yosemite spokeswoman Jamie Richards said officials were investigating the deaths, which could take several days.In India, after a rash of selfie-related deaths, the Tourism Ministry in April asked state government officials to safeguard tourists by installing signs in areas where accidents had occurred declaring them "no-selfie zones." 6571

SAN FRANCISCO (AP) — The vast region of Southern California, much of the San Francisco Bay area and a large swath of the Central Valley are about to be placed under a sweeping new lockdown in an urgent attempt to slow the rapid rise of coronavirus cases. The California Department of Public Health said Saturday the intensive care unit capacity in Southern California and Central Valley hospitals had fallen below a 15% threshold that triggers the new measures, which include strict closures for businesses and a ban on gathering with anyone outside of your own household. The Southern California region includes San Diego, Los Angeles, Orange, Riverside, Imperial, Inyo, Mono, San Bernardino, San Luis Obispo, Santa Barbara, and Ventura counties. The San Joaquin Valley region includes Calaveras, Fresno, Kern, Kings, Madera, Mariposa, Merced, San Benito, San Joaquin, Stanislaus, Tulare, and Tuolumne counties.Saturday, CDPH released new ICU capacity numbers:Bay Area: 21.7%Greater Sacramento Region: 21.4%Northern California: 24.1%San Joaquin Valley: 8.6%Southern California: 12.5%The new measures will take effect Sunday evening and remain in place for at least three weeks, meaning the lockdown will cover the Christmas holiday. 1241

SANTA ANA (CNS) - With coronavirus cases spiking, Orange County officials Wednesday ordered the closure of all bars effective at midnight and continuing until further notice, while Newport Beach officials voted to close their beaches for the Fourth of July weekend.The county order affects all bars, pubs, breweries, and brew pubs that do not offer dine-in meals. Establishments that do serve dine-in food can only sell alcohol in the same transaction as a meal.The closure order was expected ahead of the holiday weekend, given similar action already taken in surrounding counties of Los Angeles, San Diego and Riverside. Orange County officials expressed concern that if they did not act, the county would become a magnet for holiday revelers from across Southern California."While we would prefer not to close bars at this time, many of our neighboring counties have closed their bars, and it's important to take precautions to ensure the safety of the general public," County Supervisor Michelle Steel said in a statement.In an emergency meeting, Newport Beach City Council members voted 6-1 to close the city's beaches from 10 p.m. Friday through 6 a.m. Sunday. City Councilman Kevin Muldoon was the lone no vote.Mayor Will O'Neill said he agreed with Muldoon that there hasn't been an uptick in transmission of the virus due to beach activities and added, "I don't understand why LA County closed their beaches. I really don't."But since Los Angeles County and Laguna Beach have closed their beaches on Fourth of July and the state has closed parking for beaches in Orange County, Newport Beach will see an already popular holiday draw even more beachgoers than usual, O'Neill said.Also, two lifeguards have tested positive for COVID-19 and 23 others who were exposed to the ill lifeguards are now in quarantine, O'Neill said. Other lifeguards are showing symptoms, the mayor added.The mayor said the fastest growing demographic of infected patients are in their 20s and 30s."They're going to bars, going to house parties, not doing a great job of social distancing," O'Neill said, adding that he hopes they will now "take this seriously" as officials have to retreat on business and beach activity."I cannot in good conscious add more onto our lifeguards," he said. "We just can't responsibly ask our lifeguards to do more with less."O'Neill also implored beachgoers to stay away during the holiday weekend."Don't make our lifeguards and police chase you off," he said. "This is a hard enough year... This is a time we step up to where we need to be."The county's bar closure decision came on a day when county health officials announced 570 more coronavirus cases and five more deaths, bringing the county's totals to 14,413 cases and 345 fatalities. On Tuesday, the county reported a one-day record 779 newly confirmed cases.Last week was the deadliest of the pandemic in Orange County, with 56 deaths reported. Since Sunday, the county has reported 22 fatalities.The number of hospitalized patients in Orange County rose from 510 on Tuesday to 542 Wednesday, with the number of patients in intensive care increasing from 176 to 192.The county has performed 241,027 COVID-19 tests, with 7,642 documented recoveries as of Tuesday.Gov. Gavin Newsom said earlier this week that Orange County, along with Solano, Merced and Glenn counties, had been added to the state Department of Public Health's watch list due to increasing percentages of positive tests.The county's case rate rose from 115.2 per 100,000 residents on Tuesday to 126.4 per 100,000 on Wednesday. The positive test rate increased from 9.9% to 10.4% on Wednesday, according to health officials.The state has set a desired standard average of 25 positive cases per 100,000 over a 14-day period, and a seven-day average positivity rate of 8%.The three-day average increase of hospitalized patients is 9%, creeping up on the state's threshold of 10%. But that is down from 9.7% on Tuesday.Health officials insisted Orange County is in good shape in terms of hospital beds available. The county has 38.2% of its intensive care unit beds available, above the state threshold of 20%, and has 64.6% of its ventilators available, above the state standard of 25%.The city of Laguna Beach, which had already canceled its planned Fourth of July fireworks display, will close its beach on Saturday. The City Council also left open the possibility of extending the closure throughout the weekend if larges crowds begin to gather.County Supervisor Andrew Do urged all residents and business owners "to be extra cautious this holiday weekend."Supervisor Lisa Bartlett warned Tuesday that since the county has been managing cases at congregate living facilities, the current spike in cases is the result of community transmission.The best way to stem the tide of community transmission is to encourage facial coverings and social distancing, she said.Do on Tuesday announced a contract with Latino Health Access for a new program providing more outreach to residents in the county's hot spots of Santa Ana and Anaheim."There is no question in my mind now for the need for social distancing, good sanitation practices and face coverings," Do said."With the Fourth of July weekend coming if we are not careful about protecting each other we may reach a point where we need to shut down parts of the county and economy."The escalating numbers of infections and deaths "should really silence to a large degree any debate over the necessities for these measures I mentioned earlier," Do said. "It's no longer a political question or issue -- it's really a health issue."Eight out of the 10 highest case rates in the county are in Anaheim and Santa Ana, Do said.Do said he expected a rise in cases when the economy was reopened, "But I have to admit... within the last two to four weeks they have been a little bit alarming."Do emphasized that people living in the nation illegally should not fear participating in the new outreach program for local residents."Undocumented immigrants should not be fearful about being tested," Do said. "No immigration status will be asked or shared with anyone... We want to be culturally sensitive and respond effectively in a way that will penetrate these disadvantaged communities."The program will also include a mobile response team to help stem any spread in schools when they reopen, Do said. 6391
