Overview
- Sacramento County Public Health, which announced the cases Monday, said two unvaccinated children tested positive and are recovering in isolation.
- Investigators are tracing contacts and telling people who were exposed to quarantine and to call a doctor before visiting a clinic.
- Health officials say the regional cluster likely began when an unvaccinated toddler caught measles while traveling through South Carolina and then returned to California.
- A contagious child may have exposed more than 100 children at an educational program, with one report placing the group at about 130.
- California has logged measles cases in several counties with totals in the mid-30s this year, and state leaders warn low vaccine uptake fuels wider spread.
