SAN DIEGO, CA - February 5, 2026 - Health officials across the nation, including those in San Diego County, are issuing increasingly urgent appeals for widespread measles vaccination as cases continue to climb at a rate not seen in decades. While San Diego County has, thus far, remained free of locally acquired measles infections, experts warn that the growing number of outbreaks in other states poses a significant risk to the region's unvaccinated population. This surge is sparking concerns about a potential epidemic and is prompting a renewed focus on public health infrastructure and vaccination rates.

Dr. Cameron McBride, San Diego County's Deputy of Public Health, emphasized the gravity of the situation. "Measles is not simply a childhood illness. It's a highly contagious, airborne disease that can lead to severe complications, particularly in infants, pregnant women, and individuals with compromised immune systems. Even seemingly healthy individuals can experience pneumonia, encephalitis (brain swelling), and even death," Dr. McBride stated in a press conference earlier today. "We are seeing a worrying trend nationally, and complacency is our greatest enemy."

The current outbreak isn't isolated. Recent hotspots have been identified in several major metropolitan areas, most notably Los Angeles County, which has been battling a persistent cluster of cases since late 2025. Other states, including Florida, Texas, and New York, are also reporting increased incidence. This geographic spread is largely attributed to declining vaccination rates over the past several years, fueled by misinformation and vaccine hesitancy.

Public health officials attribute the decline to several factors. A significant contributor is the spread of false information online regarding vaccine safety, leading some parents to delay or forgo vaccination for their children. Another issue is access to healthcare, particularly in underserved communities, where preventative care like vaccinations may not be readily available. The lingering effects of the pandemic, with disrupted routine medical appointments, have also played a role.

The measles vaccine, typically administered as part of the MMR (measles, mumps, and rubella) vaccine, is remarkably effective. Two doses are recommended: the first between 12 and 15 months of age, and the second between 4 and 6 years old. The CDC states that two doses of the MMR vaccine are approximately 97% effective in preventing measles. However, even those who received the vaccine decades ago may require a booster shot to maintain immunity, particularly as immunity can wane over time.

For adults unsure of their vaccination status, health officials recommend checking with their healthcare provider or reviewing old medical records. Antibody tests can also determine if an individual has immunity to measles, though these are not always readily available or covered by insurance. County health services are working to expand access to affordable vaccination clinics and educational resources.

The concern extends beyond individual health. Measles has a high reproduction number, meaning each infected person can spread the disease to a large number of susceptible individuals. This can quickly overwhelm healthcare systems and disrupt daily life. Schools, daycare centers, and other communal settings are particularly vulnerable to outbreaks. San Diego County officials are working closely with schools to ensure high vaccination rates among students and staff.

The County of San Diego Health and Human Services Agency is actively monitoring the national situation and is prepared to implement stricter measures, such as temporary school closures or mandatory vaccination requirements, if necessary. "We are hopeful that we can prevent a significant outbreak in San Diego County, but that will require a collective effort. We urge all residents to take this threat seriously and get vaccinated," Dr. McBride concluded. Residents can find more information and schedule appointments by visiting the County's website at [ https://www.sdcounty.ca.gov/ ]. The agency is also running a public awareness campaign through social media and local news outlets to combat misinformation and promote vaccination.

The national resurgence of measles serves as a stark reminder of the importance of vaccination in protecting public health. Ignoring this threat could have devastating consequences, not just for individuals but for the entire community.
