Measles in California: What We Know and Why Cases Are Spiking

Two new cases of measles just popped up in Sacramento County, pushing the local total to five. It’s a quiet, unsettling development—I can almost hear the hum of the office AC as the newsroom processes the latest update from health officials. Both of these new patients are children, neither of whom had been vaccinated, and they’re currently in isolation recovering.

Misryoum analysis indicates that the situation is part of a much broader, worrying trend. We’ve seen 1,671 cases across the U.S. so far in 2026, and a staggering 92% of those infected were unvaccinated. Dr. Olivia Kasirye, the local public health officer, put it bluntly: this is concerning, and it really underscores how fast this thing travels.

Measles isn’t just a rash. It lingers in the air for up to two hours after an infected person leaves a room. It’s highly contagious, and complications can be brutal—think pneumonia or even brain swelling. It feels almost strange to be talking about this in 2026, considering the disease was declared eliminated in the U.S. back in 2000. But here we are, and Misryoum reporting shows that at least 28 states have already logged cases this year.

Actually, the rise is tied to a mix of things: lower vaccination rates, global travel, and some unfortunate, persistent misinformation. Dr. Peter Chin-Hong, an infectious disease expert, described the country as a dry forest waiting for a match. It’s a vivid image, maybe a bit dark—or maybe not, given how fast the numbers are shifting. If we lose our elimination status, we’re looking at more hospitalizations and, inevitably, more deaths. It’s a bit embarrassing, honestly, to have the tools to stop this and still be losing ground.

In California, we’re doing better than some places. We have high vaccine requirements—thanks to that 2014 outbreak—and our kindergarten immunization rates stay around 96%. That’s above the 95% threshold needed to stop transmission, so we aren’t quite at rock bottom. Yet, the trend is dipping. Complacency is the real enemy here.

If you’re worried about symptoms, look for the basics: high fever, cough, runny nose, and red, watery eyes. The rash usually shows up a few days later, starting on the face before spreading. It’s easy to dismiss as something mild, but the experts keep telling us to take it seriously.

The gold standard remains the two-dose vaccine. It’s 97% effective. It’s safe. It’s just… it’s the best shot we have. If you aren’t vaccinated, you’re at risk. That’s really the long and short of it.
