LOS ANGELES (KABC) -- If you've got tickets to a big event coming up soon, you might want to check with the venue to see if it's still on.
A number of Los Angeles-area events have been canceled or postponed as the county reported its highest number of daily infections in nearly four months.
The county reported 3,512 new cases in its daily update issued Sunday and nine additional deaths associated with the virus -- the third consecutive day with more than 3,000 new cases after months of lower totals.
The number of county residents hospitalized with COVID-19 increased by just one to 743 Sunday, with 180 of those patients in intensive care, the same as Saturday's total.
The increase is coming as the omicron variant is making its way across the country, now detected in 39 states.

Grand Park is operated by the Music Center, Ducore said. The COVID-19-prompted change was made in consultation of the Los Angeles County Department of Public Health to protect the health and safety of the public, performers, crew and staff.

Thursday's planned performance was also canceled "for the wellness and safety of our guests, cast and crew,'' along with performances planned for Friday and Saturday, Martin said.
Ticket holders will be contacted shortly with rebooking or refund options and should contact their original point of purchase with questions, Martin said.
UCLA-North Carolina men's basketball game
UCLA's men's basketball game against North Carolina planned for Saturday in Las Vegas was canceled due to COVID developments within the Bruins' program, the university announced.
UCLA's team-related activities have been paused, and the status of future games is to be determined.
Plus, according to a tweet posted Saturday afternoon, the Bruins will no longer play against Cal Poly in a nonconference game at Pauley Pavilion on Wednesday.
UCLA said the game was canceled due to COVID developments within the Bruins' program and will not be rescheduled.
Other team-related activities have been paused and the status of future games is to be determined, according to UCLA.
L.A. County is fighting back against the increase with new sets of rules for attendance at large gatherings.
If you want to get into any kind of mega event, either inside or outdoors, you'll need to show proof of being fully vaccinated, or recent negative test results. If you get an antigen test, it has to be within one day of the event, while for a PCR test it's two days.
"While things are definitely not going in the direction we want them to, we do have more tools to help protect ourselves this year than we did at this time last year, but we urgently need to use them," said county health director Barbara Ferrer.
But even getting a rapid test is turning out to be more challenging these days.
While the Dodger Stadium parking lot has reopened as a testing site, many local drugstores are out of stock for the at-home test kits.
Local leaders are reminding residents to be vigilant during the holidays.
"Get boosted," said Los Angeles Mayor Eric Garcetti. "Get vaccinated if you still haven't. And make sure you practice the safe social distancing so we'll get through the holidays without the deaths we saw last year."
