San Diego County public health officials reported 284 new COVID-19 infections and four deaths from the illness, raising the county's total to 41,608 cases and 725 deaths.
Three women and a man died between Aug. 31 and Sept. 6 and their ages ranged from early 60s to late 80s. All had underlying medical conditions.
Of the 8,311 tests reported Thursday, 3% returned positive, decreasing the 14-day rolling average of positive tests to 4.4%, well below the state's 8% guideline. The seven-day average number of tests performed in the county is 6,236.
Of the total positive cases in the county, 3,253 — or 7.8% — have required hospitalization since the pandemic began, and 775 — or 1.9% — were admitted to an intensive care unit.
County health officials reported three new community outbreaks on Wednesday, bringing the number of outbreaks in the past week to 23. Two of the outbreaks were in private residences and one in a business setting.
The number of community outbreaks remains well above the county's goal of fewer than seven in a seven-day span. A community setting outbreak is defined as three or more COVID-19 cases in a setting and in people of different households in the past 14 days.
Of Thursday's cases, another 69 were tied to San Diego State University, raising the total number of confirmed infected students on- and off- campus to 509 since the fall semester began Aug. 24
About 75% of students testing positive live in off-campus housing not managed by the university, with 73% of the cases among the freshman and sophomore classes.

The university extended its stay-at-home order for students, directing them to stay in their current residences, except for essential needs, through 9 a.m. Monday. Violations of the order may result in disciplinary action, the college said.
Luke Wood, SDSU's vice president for student affairs and campus diversity, said the university was working with a security company to enforce public health code regulations. He said the company was engaging in patrols around the College Area and reporting possible violations to the university.
Wood said the most serious violations could result in suspension or expulsion from the university. He said some organizations have been cited, as well, mostly fraternities or sororities.
On the question of how much authority the university has in students' off-campus lives, Wood was vague, but said SDSU has "some authority" in the College Area.
He also said there has been "a significant reduction" of public health violations, and that "the important thing is that the (regulations) are working."
All of the university's in-person classes, which SDSU President Adela de la Torre said comprised just 7% of all courses, were moved online Sep. 2. SDSU also paused all on-campus athletics training and workouts for two weeks starting Sep. 3 due to COVID-19.
The university announced some very limited courses will be made available in person starting today. Most of these courses have eight or fewer students.
State data released Tuesday showed San Diego County losing some ground in its fight against COVID-19, with the number of new cases per 100,000 people reaching 6.9 and the percentage of positive tests at 4.2%, close to slipping into the "widespread" tier like much of the rest of the state.
The county is in Tier 2 or the "substantial" tier, the state's second-most strict. With a slight bump in new cases per 100,000, San Diego could find itself closing recently opened businesses.
San Diego County Supervisor Nathan Fletcher said that though the county's numbers are close to the highest tier, they aren't there yet. It would take two consecutive weeks of widespread data before the county could be moved into a higher tier — or lower tier if the numbers drop significantly.
The numbers for the widespread tier — which every other Southern California county besides Orange County finds itself in — are 7 or more new cases per 100,000 and more than 8% positive testing. Just one of those above guidelines could be enough to push a county up a tier.
The county is expanding its walk-in testing capabilities, adding sites at Cal State San Marcos, University of San Diego, San Diego State University, the Tubman-Chavez Community Center, Mar Vista High School and the San Ysidro Port of Entry.

Supervisor Greg Cox said the Great Plates program has been expanded by FEMA and the California Office of Emergency Services through Oct. 9 to provide three meals a day for seniors, or one meal a day for people over the age of 18 with a health condition. Nearly 3,000 people have enrolled in twin programs, but Cox said there are spaces for "many more" to sign up.
