As Orange County school districts reopen, county officials warn residents to remain vigilant to prevent another COVID-19 spike.
Five local schools began in-person teaching on Thursday, and another five schools are expected to join next week.
Orange County is one of 33 counties in California permitted to resume in-person teaching because of improving coronavirus metrics or lower figures.
All schools returning to classroom instruction will also use online teaching, employing a hybrid model to maintain social distancing.
The county has 28 total schools; harder-hit cities, such as Anaheim and Santa Ana, have not been given the green light to resume in-person instruction.
The county hit a coronavirus peak in July but has since seen a steep drop off in new cases, hospitalization figures and other metrics.
