SAN DIEGO (CNS) - Despite an adjusted daily COVID-19 case rate of 7 per 100,000 population, San Diego County was again able to avoid being pushed into the most restrictive purple tier of California's four-tier reopening system.High rates of testing helped the county stay in the red tier, county officials said. The positive adjustment is given by the state to counties that are testing at higher levels than the state's median. That adjustment prevented the county from landing in the purple tier, which would have placed indoor activities at restaurants, movie theaters, gyms and a number of other locations in jeopardy."Remaining in the red tier is good news, but the new adjusted rate is not. The new figure clearly shows the region is not moving in the right direction," said Dr. Wilma Wooten, San Diego County public health officer. "It is extremely important San Diegans follow the local health guidance to slow the spread of COVID-19 and keep the region from falling into the purple tier."The county's unadjusted case rate for the week of Oct. 4-10 rose from 7.2 to 7.8 cases per 100,000 residents. It was adjusted down to 7 per 100,000. The data are reported on a one-week delay.While the testing positivity percentage for the region also increased from 3% to 3.3%, it still remains low enough for this metric to remain in the orange tier. If a county reports statistics meeting metrics in a higher tier for two consecutive weeks, it will move into that more restrictive tier for a minimum of three weeks.The state's health equity metric, which looks at the testing positivity for areas with the lowest healthy conditions, dropped from 5.7 to 5.5% and remained in the red tier. This metric does not move counties backward to more restrictive tiers, but is required to advance.County public health officials reported 265 new COVID-19 infections and four deaths related to the illness Tuesday, raising the region's total case count to 53,000 and the death toll to 857.Four men died between Oct. 11 and Oct. 18, and their ages ranged from mid-50s to early 80s. All had underlying medical conditions.Of the 9,110 tests reported Tuesday, 3% returned positive, bringing the 14-day rolling average percentage of positive cases to 2.8%, far below the state-set target of less than 8%.Of the total COVID-19 cases in the county, 3,788 or 7.1% have been hospitalized, with 876 -- or 1.7% -- spending at least some time in an intensive care unit.Five new community outbreaks were reported Tuesday, two in businesses, one in a restaurant/bar setting, one in a K-12 school setting and one in a faith-based institution. In the past seven days, 30 community outbreaks were confirmed, well above the trigger of seven or more in a week's time.A community outbreak is defined as three or more COVID-19 cases in a setting and in people of different households over the past 14 days.The county uses community outbreaks to get a larger sense of the pandemic locally, but the state does not include the statistic in its weekly report.Wooten said 95% of the county's cases were not related to a marked community outbreak, a clear indicator the illness has spread throughout the county.The Vista Unified School District, meanwhile, fully reopened its schools Tuesday morning, becoming one of the first in the region to do so.The district invited students back to 28 schools, eschewing some of the more cautious measures some other school districts are taking, moving into its Phase 3 reopening plan. The plan, "Vista Classic," allows every school in the district to reopen at full capacity. Parents and guardians will still be able to keep students in "Vista Virtual," the district's distance-learning program, if they so choose."Our health and safety measures were working well, with mask wearing and handwashing particularly strong on all campuses," Vista Superintendent Matt Doyle said after visiting campuses. "We will continue to refine arrival, dismissal, and lunchtime routines for students as they relearn how to interact with their friends in this new social distancing environment."The district said it will attempt to have social distancing as much as possible, but will allow as many as 38 students in a single classroom, so desks will not be spaced six feet apart.A rally Thursday by teachers and parents at Foothill Oaks Elementary School attempted to dissuade the Vista Unified School Board from reopening, with many educators believing the safety measures inadequate.According to KPBS, plexiglass barriers were not provided to teachers. Instead, they were given PVC pipes and plastic liner to create makeshift protection from students returning to in-person learning. 4675

SAN DIEGO (CNS) - A man who fired a pellet gun at Navy SEAL instructors and trainees conducting a nighttime training exercise near Liberty Station was sentenced on Thursday to a year in jail.Scott Douglass Weaver, 48, pleaded guilty last month to making an attempted threat on a witness and brandishing a replica firearm.Because of credit for time already served, Weaver will spend about 80 more days in local custody before being released, authorities said.Dispatchers received a report of a man shooting at Navy officers shortly before 10:45 p.m. on July 23 in the 2500 block of Laning Road and Weaver was arrested. No military personnel were injured, according to the Navy.Police did not say if Weaver had a motive for firing at the SEALs or if he was even aware of who he was shooting at.In light of the shooting, the Naval Special Warfare Command said it would evaluate its training procedures. Prospective SEALs are known to train in Coronado, the Silver Strand and areas in San Diego Bay. 1003

SAN DIEGO (CNS) - A report released Thursday by the International Boundary and Water Commission found a significant presence of wastewater in border channels in the Tijuana River Basin impacting San Diego.In the report, "Binational Water Quality Study of the Tijuana River and Adjacent Canyons and Drains," scientists from the United States and Mexico collected samples from of seven transboundary channels.The sampling and laboratory analysis for the study were performed from December 2018 to November 2019. The findings indicate the presence of treated and untreated domestic and industrial wastewater.The scientists analyzed 267 different parameters in water and 204 parameters in sediment for pathogens, metals, industrial organics, pesticides, as well as conventional parameters typically found in wastewater. Of the parameters tested, 131 were not detected and 136 had detectable levels.Parameters that exceeded standards in both countries at all monitoring sites are those associated with the presence of wastewater, including ammonia, biochemical oxygen demand, chemical oxygen demand, oils and greases, phosphorus, nitrates, methylene blue active substances and coliform bacteria.Data analysis indicates that the parameters which exceeded standards had originated as uncontrolled sewage spills from Tijuana. Disposal of solid waste or trash contributes to the presence of certain parameters exceeding the standards, such as the organic compound DEHP. Commonly used in the manufacture of plastics, DEHP exceeded applicable standards at all monitoring sites and could have leached from plastic accumulated in the canyons and Tijuana River.The results showed that certain parameters of concern -- Hexavalent Chromium and the pesticides DDT and Aldrin -- were either not detected or found in very low amounts below the limits established in both countries' applicable regulations. Likewise, metals such as copper, nickel and zinc, which are commonly used in the metal plating industry, were detected at levels within applicable standards in both countries.The report also includes recommendations related to control of industrial wastewater discharges in Tijuana, increased resources and assistance for wastewater collection and treatment systems in Tijuana, and continued joint water-quality monitoring and field inspections to detect and respond timely to wastewater flows. 2389

SAN DIEGO (CNS) - A Utah man who robbed a Carlsbad Motel 6 at gunpoint, then was arrested attempting to re-enter the United States, was convicted of federal robbery and firearm-related charges, the U.S. Attorney's Office announced Wednesday.Lance Lamont Lavert of Salt Lake City, 37, was convicted Tuesday by a San Diego federal court jury for the July 9, 2018, morning robbery of the motel on Paseo Del Norte.Prosecutors said Lavert and his girlfriend asked for a room, but were denied due to a lack of ID.Lavert then pointed a gun at the motel clerk and her manager, demanding money. When the clerk and manager ran, Lavert leapt over the counter, kicked in the door of the bathroom where the clerk was hiding, dragged her back to the cash register by her hair and pistol-whipped her in the head, court documents state.Along with 5 in cash, Lavert and his girlfriend made off with the clerk's car keys and stole the clerk's car, prosecutors said.Lavert was arrested two days later trying to cross the border back into the United States. The revolver he used in the robbery was found in his waistband.In addition to committing the robbery, Lavert was convicted for possession of a gun while having several prior felony convictions, including for arson in Utah and assault with a deadly weapon out of Imperial County, the U.S. Attorney's Office said.Lavert's girlfriend pleaded guilty prior to the trial, according to prosecutors. 1440
