SAN DIEGO (CNS) - A stabbing at a College Area bus stop left a man badly injured Friday, authorities reported.The 50-year-old victim was waiting for a bus in the 6900 block of El Cajon Boulevard when the assailant approached and began arguing with him shortly before 11:30 a.m., according to San Diego police.The quarrel ended when the stranger pulled a knife and stabbed the other man in the arm, then fled on foot, Officer Tony Martinez said.Patrol personnel applied a tourniquet to the victim's bleeding arm and performed CPR on him prior to the arrival of paramedics, who took him to a hospital for treatment of serious but apparently non-life-threatening trauma.Witnesses reported that the assailant -- described as a heavyset, heavily tattooed man in his 20s or 30s, wearing a red shirt and black bandana- style mask -- left the area eastbound and appeared to enter a nearby motel, police said. He remained at large in the early afternoon.It was unclear what sparked the argument between the two men. 1014

SAN DIEGO (CNS) - Former San Diego City Councilman and Reform California Chairman Carl DeMaio announced his intent Monday to enter the race for the only Republican-held congressional seat in San Diego County. In a statement announcing his candidacy for the 50th Congressional District seat, DeMaio framed the decision to run as one of ``fight or flight.'' He also lambasted the state's Democratic dominance, arguing the state has shifted to the left in an untenable way. ``Too many Californians are fleeing our state because of the extreme socialist agenda being imposed on us by Democrat politicians, but I refuse to flee: I choose to stand and fight,'' DeMaio said. ``In California, voters have mostly only been given two choices: socialists or ineffective cowards.'' The 50th District seat is currently represented by Rep. Duncan Hunter, R-Alpine, who was indicted last August, along with his wife, on five dozen criminal charges, including conspiracy, wire fraud and record falsification, for allegedly misusing campaign funds. Margaret Hunter has since pleaded guilty to conspiracy and is cooperating with prosecutors. Her husband maintains his innocence. Hunter won a sixth term last November, defeating Democratic candidate Ammar Campa-Najjar with 51.7% of the vote. The path to a seventh term appears more fraught for Hunter, whose trial is slated to begin Sept. 10 in federal court. With rumors of a possible resignation swirling, a cluster of Republican politicians have announced plans to run for the seat in the event Hunter foregoes a run or cannot legally run in 2020. El Cajon Mayor Bill Wells, Temecula Mayor Matt Rahn, former Escondido Mayor Sam Abed and former U.S. Navy SEAL Larry Wilske have all joined the race as Republicans. Former Rep. Darrell Issa, who declined a re-election run in the 49th District in 2018, could also join the race. Campa-Najjar, meanwhile, essentially never stopped campaigning after losing last year and is likely to have a war chest prepared for another attempt to flip the seat. ``More than half a dozen Republicans are now eyeing a challenge against me for CA-50,'' the Campa-Najjar campaign said in a statement last Friday. ``This is an internal battle that party elites will have to figure out amongst themselves.'' In previous challenges for major office, DeMaio lost to Rep. Scott Peters, D-San Diego, in 2014 and to Bob Filner in the 2012 race for San Diego mayor. DeMaio was also the leader of a failed attempt to repeal the state's gas tax in 2018. The California primary is scheduled for March 3, 2020. 2568

SAN DIEGO (CNS) - According to state data released Tuesday, San Diego County will remain in the second, or red, tier of the state's four-tier COVID- 19 reopening plan for at least another week.The county's state-calculated, adjusted case rate is 6.5 new daily infections per 100,000 people, down from last week's 6.7. The unadjusted case rate is down to 7 from last week's 7.2. Because San Diego County testing levels were above the state median testing volume, the county's adjustment level was decreased.On the last two Tuesdays, the county narrowly avoided being pushed back into purple tier, the most strict in the state's reopening plan. The state- set threshold of case rate to avoid the purple tier is below 7 per 100,000.To move into the less-restrictive orange tier, a county must have a rate below 3.9 per 100,000 people.County public health officials reported 161 new COVID-19 infections and three deaths on Tuesday, raising the region's totals to 48,821 cases and 806 deaths.Two men and one woman died between Oct. 2 and Oct. 4, and their ages ranged from mid-50s to early 80s. All had underlying medical conditions.Of the 8,788 tests reported Tuesday, 2% returned positive, bringing the 14-day rolling average percentage of positive cases to 2.9%. The seven-day daily average of tests was 9,277.Of the total number of cases in the county, 3,602 -- or 7.4% -- have required hospitalization and 833 -- or 1.7% of all cases -- had to be admitted to an intensive care unit.None of the 224 cases reported Monday were connected to San Diego State University, but two previously reported confirmed cases are now associated with the school outbreak, bringing the total number of SDSU cases to 1,136, according to public health officials.Those two cases were previously reported to the San Diego County Health and Human Services Agency, but only recently identified -- through continued cross-referencing between SDSU and the HHSA -- as having an SDSU affiliation.A total of 407 on-campus students, 707 off-campus students, 9 faculty or staff and 13 visitors have either confirmed or probable positive COVID-19 diagnoses. Officials said 53 of the total are considered "probable."SDSU announced last Wednesday that it was extending a pause on in-person courses through Oct. 12. Effective that day, a limited number of courses will resume in person. Most of those courses are upper-division or graduate level, and have been "determined by faculty and academic leaders to be essential to student degree completion, licensure, and career preparation," university officials said in a statement.About 2,100 students will be enrolled in an in-person course. Prior to the in-person pause, 6,200 students were enrolled in an in-person course.In the seven-day period from Sept. 28 through Sunday, 20 community outbreaks were confirmed, well above the trigger of seven or more in seven days. A community setting outbreak is defined as three or more COVID-19 cases in a setting and in people of different households over the past 14 days.A COVID-19 testing site opened this week in Chula Vista, offering 200 daily tests, five days per week.The drive-up site will provide free, no-appointment diagnostic tests from 12:30 p.m. to 8 p.m. Sunday through Thursday at the South Chula Vista Library, located at 389 Orange Avenue. The COVID-19 tests take about 5-10 minutes and the results come back in about three days.The county has expanded its total testing sites to 41 locations, and school staff, including teachers, cafeteria workers, janitors and bus drivers, can be tested for free at any one of those sites. A rotating testing program with the California Department of Forestry and Fire Protection was in the works for schools in the county's rural areas.There are no state testing requirements for children, but all school staff who interact with children must be tested every two months. If schools were to open before San Diego County headed to a more restrictive tier in the state's monitoring system, they would not be affected. However, if a move to a different tier happened before schools opened for in-person learning, it would change the game plan, county Supervisor Nathan Fletcher said.If parents want to test their children for the illness, they have options, including Rady Children's Hospital, through Kaiser Permanente or through the 41 sites the county manages. Children as young as 6 months can be tested at the county-run sites. 4449

SAN DIEGO (CNS) - According to research published Friday by UC San Diego School of Medicine and San Diego State University researchers, the risk of contracting COVID-19 from handling trick-or-treat candy that has been in contact with a coronavirus-positive person is minimal, but not zero.In the study published Friday in the journal mSystems, the researchers analyzed the viral load on Halloween candy handled by patients with COVID-19.SARS-CoV-2, the virus which causes the illness COVID-19, is primarily transmitted by respiratory droplets and aerosols. The risk of infection by touching fomites -- objects or surfaces upon which viral particles have landed and persist -- is relatively low, according to multiple studies, even when fomites are known to have been exposed to the novel coronavirus. Nonetheless, the risk is not zero."The main takeaway is that although the risk of transmission of SARS- CoV-2 by surfaces -- including candy wrappers -- is low, it can be reduced even further by washing your hands with soap before handling the candy and washing the candy with household dishwashing detergent afterwards," said co-senior author Rob Knight, professor and director of the Center for Microbiome Innovation at UCSD."The main risk is interacting with people without masks, so if you are sharing candy, be safe by putting it in dish where you can wave from six feet away," he said.As San Diego County heads into a Halloweekend, public health officials are urging members of the public to practice COVID-19 protocols -- including avoiding large gatherings such as Halloween parties and door-to-door trick-or-treating."These activities involve face-to-face interactions with people from different households," said Dr. Wilma Wooten, the county's public health officer. "If a COVID-19 infection is detected among a participant, it will be very difficult to find and notify those who may have been exposed."These traditional Halloween celebrations are not advised, and large gatherings are not allowed under state or local health guidance. The county has reported dozens of community outbreaks in the past week.For their study, the researchers enrolled 10 recently diagnosed COVID- 19 patients who were asymptomatic or mildly symptomatic and asked them to handle Halloween candy under three different conditions: Normally with unwashed hands, normally with washed hands and extensive handling while deliberately coughing.The candy was then divided into two treatments -- no post-handling washing and washed with household dishwashing detergent -- followed by analyses using real-time reverse transcription polymerase chain reaction, the same technology used to diagnose COVID-19 infections in people, and a second analytical platform that can conduct tests on larger samples more quickly and cheaply. Both produced similar findings.On candies not washed post-handling, researchers detected SARS-CoV-2 on 60% of the samples that had been deliberately coughed on and on 60% of the samples handled normally with unwashed hands. However, the virus was detected on only 10% of the candies handled after handwashing.The dishwashing detergent was effective for reducing the viral RNA on candies, with reducing the viral load by 62.1 percent.The researchers had also planned to test bleach, but noted that bleach sometimes leaked through some of the candy wrappers, making it unsafe for this type of cleaning use.The study authors underscored that the likely risk of SARS-CoV-2 transmission from candy is low, even if handled by someone with a COVID-19 infection, but it can be reduced to near-zero if the candy is handled only by people who have first washed their hands and if it is washed with household dishwashing detergent for approximately a minute after collection.Knight led the study with Forest Rohwer, viral ecologist at San Diego State University, and Dr. Louise Laurent, professor at UC San Diego School of Medicine. 3937

SAN DIEGO (CNS) - California State University police chiefs Friday banned the use of the carotid restraint and pledged to implement policing recommendations offered by a 2015 federal task force on the CSU's 23 campuses, which include San Diego State and Cal State San Marcos."As police chiefs of the California State University's 23 campus police departments, we have been galvanized by the many voices across our state and nation demanding accountability, equity and justice," the chiefs said in a joint statement. "We have seen the tragic impact of racism and bigotry, and many in our departments have experienced it personally. We are unitedly determined to take action."CSU Chancellor Timothy White and every CSU campus president supports the pledge to adopt recommendations of The President's Task Force on 21st Century Policing, reported to then-President Barack Obama in May 2015, according to the chiefs."We are determined to lead by example, joining a growing number of American cities that have committed -- collectively and collaboratively -- to address police use-of-force policies," the statement continued. "To that end, and effective immediately, we are prohibiting the use of the carotid control hold by all CSU police officers. Additionally, no CSU police officer will receive or participate in trainings that teach the carotid control hold."The task force's recommendations are organized around six pillars: Building Trust and Legitimacy, Policy and Oversight, Technology and Social Media, Officer Wellness and Safety, Community Policing and Crime Reduction, and Training and Education.The chiefs also committed to looking for ways to incorporate those concepts into the training and certification provided by the California Commission on Peace Officer Standards and Training. All CSU police officers are sworn and certified by CA POST, and receive further training in de-escalating situations that might be caused by mental health or controlled substance issues.The announcement comes as student activists across the country call on administrators to disband campus police departments and cut ties with local police. 2143
