Health advocates say containing and investigating the wave of measles cases this year comes with a hefty price tag.
Every time a new or potential measles case is reported, it requires a thorough public health investigation. That means blood tests, informing the public and tracking down people who may have been exposed.
Measles is highly contagious. One infected student at University of California, Los Angeles' campus last month exposed hundreds of people and triggered a quarantine.
State Senator Richard Pan, who’s also a pediatrician, says that these investigations take a lot of time and money.
"Here in Los Angeles, the cost associated with just containing just three measles exposures related to travel at LAX earlier this year have already cost county taxpayers more than $80,000," said Pan.
