Before this week, the state had logged five 2025 measles cases — three in February, two in March. New to the list are:

• Two cases in Tuolumne County, an adult and a person under 18. The county’s public health department said the two live in the same home and recently traveled internationally. The agency said it could not confirm their vaccination status.

A warning was issued for unimmunized people who may have been exposed March 10-11 at Summerville Union High School in Tuolumne or March 15-16 in the emergency room of the Adventist Health hospital in Sonora.

• One case in Fresno County, an adult man. The county’s public health agency, without giving details, said the case was “linked to” a Fresno County case confirmed on March 7. That initial patient had traveled internationally and, after his return, had attended a religious conference in Madera County on March 2.

The patient in the more recent case was in a WinCo grocery store in Clovis on the evening of March 13; anyone who was there at the time has been asked by the health agency to take an online survey.

As a Texas outbreak neared 280 patients, Bay Area public health officials last week urged residents to be vaccinated for measles if they have neither had the shot nor acquired natural immunity through contracting the disease.

And though the measles vaccine is said to last a lifetime, some public health officials advise a new shot for people who were vaccinated decades ago and now are 65 or older, live near an outbreak, or are preparing to travel internationally. There’s also the potential for risk among people who received a less effective vaccine given between 1963 and 1967, a report from Yale Medicine said.

The federal Centers for Disease Control has logged more than 320 measles cases this year, in 14 states. Two people are known to have died from the disease.
