The health department also announced that it spent nearly $130,000 and 3,000 staff hours in efforts to halt the spread of the outbreak, according to

California has recently seen a rise in the number of reported measles cases. Health officials in the state likewise attribute the uptick to unimmunized travelers infected elsewhere.
