SAN DIEGO (CNS) - San Diego County public health officials Sunday reported 373 new cases of COVID-19 and no new deaths, bringing the county's totals to 52,355 and the death toll remaining at 853.Officials are imploring San Diegans to maintain vigilance as positive case rates for the coronavirus continue to increase in the region."We are now concerned about the trends and we are concerned about the likelihood we could tip back to purple, Supervisor Nathan Fletcher said on Twitter today. The county is now in the red tier and the limit for the next tier is seven cases per 100,000 residents.Fletcher pointed to positive unadjusted case rates over six days (Oct. 11-16): 6.9 out of 100,000 residents, to 7.2 to 7.3 to 7.4 to 7.7 and 7.8.The county will be in the red, or "substantial," tier for at least another two weeks.But Fletcher and Public Health Officer Dr. Wilma Wooten held an emergency meeting Friday to "sound the alarm" as the future case rate appears to cross into the purple tier of the state's four-tier reopening system.With the state's monitoring system having a seven-day lag, the adjusted case rate of positive COVID-19 tests is 6.8 per 100,000 residents, up from 6.5 in the previous assessment.Nearly all non-essential indoor businesses would close under the purple tier."We are still in the red tier, but it is too close for comfort," Wooten said.The California Department of Public Health will update the county's data Tuesday.One new community outbreak was confirmed Saturday in a business. In the past seven days, 32 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.A total of 12,233 tests were reported to the county Saturday and the percentage of new laboratory-confirmed cases was 3%.The 14-day rolling average percentage of positive cases is 2.7%. The target is less than 8%.The seven-day daily average of tests is 10,573.Of 3,763 positive cases -- or 7.2% -- have required hospitalization through Saturday.Of 870 -- or 1.7% -- of all cases had to be admitted to an intensive care unit. 2504

SAN DIEGO (CNS) -- The San Diego Padres will face the Arizona Diamondbacks in their season opener at Petco Park Friday evening on an opening day unlike any other in their 52-season history.There will be no spectators present because of public health directives prohibiting public events and gatherings stemming from the coronavirus pandemic. Cardboard cutouts of players' family members and loved ones will be placed in the seats behind home plate.With the absence of fans all 30 MLB teams will use ambient background audio to create crowd sounds during the season. MLB is providing each team with an array of crowd sounds and a touchpad device that can be integrated into their ballpark sound system to help manage the playing of the sounds.RELATED: Cardboard Padres fans to fill Petco Park's stands during 2020 seasonThe crowd sounds will be audible to on-field personnel and during television and radio broadcasts.The crowd backgrounds and reactions provided to the teams are all derived from exclusive, original source audio recorded by developers of the MLB The Show video game at MLB regular season games.The audio was edited into sound cues used in MLB The Show 20, with a focus on authentically replicating crowd sound and behavior. Selected content was then further refined for real-time playback over ballpark audio systems and allows for about 75 different effects and reactions to be used during a game.The crowd sounds will work in conjunction with stadium announcers, walkup music and in-stadium video to replicate the in-game experience as closely as possible.The coronavirus pandemic prompted MLB to make several rule changes for the 2020 season, which has been shortened to 60 games per team, 102 less than usual.National League games will include the use of the designated hitter for the first time in an attempt to avoid pitchers being injured when they are batters or baserunners. The DH had been limited to American League games and interleague games when an American League team is the home team.RELATED: Local company to help fill silence during MLB seasonEach half-inning of a game going into extra innings will begin with a runner on second base in an attempt to reduce long games and the strain they place on pitchers.Teams may have up to 30 players on their active rosters for the first two weeks of the season, five more than usual. The active roster must be reduced to 28 players by Aug. 6 and 26 by Aug. 20. Teams will be permitted to have a three-player taxi squad on road trips, one of whom must be a catcher.Before the coronavirus outbreak, MLB adopted a rule requiring pitchers to face at least three batters before being relieved in an attempt to speed up the game.Major League Baseball has instituted a set of health and safety protocols intended to reduce the spread of the coronavirus.The protocols include calling for players, umpires and other on-field personnel "to practice physical distancing to the extent possible within the limitations of competition and the fundamentals of baseball;" strictly enforcing prohibitions against unsportsmanlike conduct to prevent unnecessary physical contact and support physical distancing between individuals on the playing field; requiring teams to provide expanded dugout and bullpen space; and having all non-playing personnel wear face coverings at all times in the dugout and bullpen.RELATED: Fan hoping to "share" view overlooking Petco Park during baseball seasonThe opener is Jayce Tingler's debut as Padres manager, replacing Andy Green, who was fired with eight games remaining last season when the Padres had a 69-85 record and were fourth in the five-team National League West.The Padres lost seven of their eight games under interim manager Rod Barajas to finish last in the division, 36 games behind the champion Los Angeles Dodgers.Tingler described his feelings as "excited, nervous, anxiety, I think all the feelings that naturally you should have and they're just good reminders to know that we're alive."Tingler spent last season as the major league player development field coordinator for the Texas Rangers.Right-hander Chris Paddack will be the Padres starting pitcher. He was 9-7 with a 3.33 ERA in 26 starts as a rookie last season and 1-0 with a 1.08 ERA in three starts against the Diamondbacks.The Padres will be the second team in 100 years to start a rookie or second-year pitcher on opening day in back-to-back seasons, according to the Elias Sports Bureau, the official statistician for MLB. The other was the 1966- 67 Kansas City Athletics with Hall of Famer Catfish Hunter in 1966 and Jim Nash in 1977.Left-hander Madison Bumgarner will start for Arizona in his debut with the Diamondbacks after pitching for the San Francisco Giants since 2009. Bumgarner was the Giants opening day pitcher last season against the Padres, allowing two runs and five hits in seven innings in a 2-0 loss.The 6:10 p.m. game will be telecast by Fox Sports San Diego. 4966

SAN DIEGO (CNS) - San Diego County schools are allowed to reopen for in-person teaching starting Tuesday, a day after a flurry of businesses throughout the county resumed indoor operations.Tuesday marks two weeks since San Diego County was removed from the state's COVID-19 watch list and nearly three weeks that the county's case rate has remained under 100 cases per 100,000 people.Remaining below that metric has paved the way for K-12 schools to reopen for in-person teaching, but many districts are expected to take a cautious approach to reopening.Schools that choose to reopen must follow state guidance, including mandatory face covering usage for students in third grade through high school, increased cleaning and disinfecting practices and implementing a six-foot distance requirement, where possible, in classrooms and non-classroom spaces.On Monday, San Diego County businesses including movie theaters, gyms, museums and hair and nail salons resumed indoor operations, with modifications, under newly issued state guidance. Restaurants, places of worship and movie theaters are only allowed up to 25% occupancy or 100 people -- whichever is less. Museums, zoos and aquariums are also required not to exceed 25% occupancy.Monday night, the county implemented a new policy that restaurant patrons sitting indoors must wear masks at all times, except when eating or drinking. Outdoor patrons may still remove masks while not consuming food or beverages.Gyms, dance studios, yoga studios and fitness centers may operate with 10% occupancy. Hair salons, barbershops, tattoo parlors, piercing shops, skin care and cosmetology services and nail salons may operate indoors with normal capacity, but a new policy states they must keep an appointment book with names and contact information for customers to track potential future outbreaks.San Diego County Supervisor Greg Cox thanked San Diegans for working hard to bring the case rate down but offered a word of caution on Monday."This is not a green light, this is a yellow light," he said. "We can't gun the engine of the economy full throttle yet."Dr. Wilma Wooten, the county's public health officer, said the county would follow state guidelines that retail businesses are to be restricted to 50% occupancy. Wooten said she was seeking clarification on grocery stores for the same restriction.All indoor businesses must still abide by social distancing and face-covering mandates, as well as having a detailed safe reopening plan on file with the county.County public health officials reported 304 new COVID-19 cases on Monday, raising the county's cumulative cases to 38,604. No new deaths were reported, keeping the county's deaths tied to the illness at 682.Of 5,731 tests reported Monday, 5% returned positive, raising the county's 14-day rolling positive testing rate to 3.7%, well below the state's 8% guideline. The seven-day average number of tests performed in the county is 6,543. 2960
