State Measles Alert Spurs Humboldt Health Vigilance Despite No Cases

Shasta County’s cluster of eight confirmed measles cases has prompted heightened vigilance across the north coast, even as the Humboldt County Department of Health and Human Services confirmed there are no cases of measles in Humboldt “thus far.” Local health leaders say rapid communication and preparedness remain the county’s priority as state officials warn of rising national activity.

“The California Department of Public Health (CDPH) issued a statewide health alert on Feb. 12, 2026 urging health-care providers to be on heightened alert for measles after a cluster of cases was confirmed in Shasta County and several other California counties.” Last week, the California Department of Public Health and Shasta County confirmed eight total cases of measles in Humboldt County’s eastern neighbor.

CDPH Director and Public Health Officer Dr. Erica Pan framed the situation as part of a national trend, saying, “The United States is experiencing the highest numbers of measles cases, outbreaks, hospitalizations and deaths in more than 30 years, driven by populations with low vaccination rates. We all need to work together to share the medical evidence, benefits, and safety of vaccines to provide families the information they need to protect children and our communities.” State guidance has also urged unvaccinated residents to take the jab and warned that measles is “severe, highly contagious and sometimes fatal,” prompting health-care providers to monitor for suspected cases.

Humboldt County Health Officer Dr. Candy Stockton emphasized regional coordination and local preparedness, saying the county “works in close collaboration with the state to investigate suspected cases and stop the spread of the highly contagious virus.” She added that “the Health Officers from Shasta, Trinity and I were in contact sharing information within a few hours of the time the first case in Shasta County was diagnosed. Because we have seen spread to neighboring counties in other outbreaks across the country, we’ve been preparing for the possibility of cases in Humboldt since the first case in Shasta was diagnosed.”

Public-health profiles underscore uneven health burdens in neighboring counties that can influence outbreak response and risk. CDPH County Health Status Profiles 2022, using 2018–2020 data, show a wide county range in crude death rates for Alzheimer’s disease - a high of 86.3 deaths per 100,000 in Shasta County compared with a low of 17.7 in Humboldt County - and a wide range for cerebrovascular disease, with Humboldt’s crude death rate at 114.6 per 100,000 and Kern County at 31.8 per 100,000. Those long-term health differences are part of the broader public-health landscape as officials work to contain an acute, vaccine-preventable threat.

Key details about the Shasta cluster remain to be released by county health officials, including patients’ ages, vaccination status, hospitalization information and any identified exposure sites. Humboldt officials continue to monitor the situation, coordinate with the state and neighboring counties, and stand ready to investigate suspected cases and implement containment measures until the county’s “no cases” status changes.
