The San Joaquin Valley has had one case of measles -- reported by health officials in Stockton -- so far this year.
Statewide, there have been 60 cases reported to the California Department of Public Health. Orange County reported 22 and Los Angeles another 10.
Last year, only six cases of measles had been reported statewide through May.
It's been 20 years since Fresno County reported a measles case, said David Luchini, assistant director of the county's Department of Public Health.
The central San Joaquin Valley has high immunization rates, Luchini said. And there are low numbers of families who cite personal exemption reasons for not getting children immunized, he said. "That leaves us with less of a vulnerable population."
But county health officials are concerned that more measles cases are being reported in California, Luchini said. "As there are more cases around the state, there's a higher chance of having a case here in Fresno County."
