All sixth-graders at an Orange County school were quarantined this week after a COVID-19 outbreak infected dozens of students, the Placentia-Yorba Linda Unified School District said in a news release. The sixth-graders at Travis Ranch School in Yorba Linda were quarantined for the week beginning Monday after the Orange County Health Care Agency identified cases at the school. Regina Chinsio-Kwong, deputy Orange County health officer, told KABC that most of those infected were either unvaccinated or partially vaccinated. Orange County did not have an indoor mask mandate prior to that. Orange County has seen a 15% increase in COVID hospitalizations over the last three weeks, alongside hospitalization spikes of 26% in San Bernardino County, 36% in Riverside County and 47% in San Diego County.
