California Measles Cases Rise to 34 Amidst Ongoing Outbreak

California is currently contending with a growing measles outbreak, as the state has now recorded a total of 34 confirmed cases. This figure includes two recent infections identified in Sacramento County, both of which involved children who had not been vaccinated.

According to health officials, measles poses little threat to individuals who have received the measles, mumps, and rubella (MMR) vaccine, but it can present a significant risk to those who are unvaccinated.

Dr. Olivia Kasirye, the Public Health Officer for Sacramento County, expressed concern over the ongoing spread of the disease. In a statement, she noted, "The continued identification of measles cases in our community is concerning and underscores how quickly this disease can spread."

Dr. Kasirye emphasized the importance of preventive measures, stating, "Measles can cause serious illness but it’s important to remember these cases are preventable. Vaccination is the most important step people can take right now to protect themselves and others."

Despite the increase in cases, health authorities maintain that the risk to the general public "remains low." However, they are advising the public to remain "hyper-aware and take steps to protect themselves and others."

Measles is recognized as the world's most contagious disease. The Centers for Disease Control and Prevention (CDC) notes that the MMR vaccine offers durable protection against all measles strains, and most children receive this vaccination.

Symptoms of measles typically appear between seven and 14 days after exposure and can include a high fever, a runny nose, a cough, and a characteristic rash.

Nationwide, measles cases have been reported in 33 states, with approximately 92% of these cases occurring in individuals who were unvaccinated or had an uncertain vaccination status. The United States has reported over 1,671 confirmed measles cases in the year 2026 to date.
