HELENA, MT - April 1st, 2026 - The Montana Department of Public Health and Human Services (DPHHS) today announced a concerning expansion of the measles outbreak in Lewis and Clark County, with five new confirmed cases bringing the total to nine. This development is prompting renewed calls for vaccination and heightened public health awareness across the state.

The newly confirmed cases, all geographically clustered within Lewis and Clark County, underscore the highly contagious nature of measles and the potential for rapid spread, particularly among unvaccinated populations. DPHHS spokesperson Adriene Brecheisen emphasized the severity of the situation, stating, "We are deeply concerned about this growing outbreak and urge anyone who is not vaccinated against measles to do so immediately. Measles is not a mild illness; it can lead to serious complications, especially for vulnerable individuals."

Measles, a highly contagious viral infection, is characterized by fever, cough, runny nose, and a distinctive rash that typically appears one to two weeks after exposure. However, the virus's incubation period means individuals can be contagious for four days before the rash manifests, making containment particularly challenging. This pre-rash transmissibility contributes significantly to the difficulty of controlling outbreaks.

The current outbreak is raising questions about vaccination rates within Lewis and Clark County and, more broadly, across Montana. While Montana generally maintains high vaccination rates for childhood diseases, pockets of unvaccinated individuals - often due to philosophical or religious objections, or limited access to healthcare - can create vulnerabilities that allow the virus to flourish. Public health officials are carefully analyzing vaccination data to pinpoint areas of concern and tailor outreach efforts.

Complications and Vulnerable Populations

Measles isn't merely a discomforting illness; it can lead to serious, even life-threatening, complications. These include pneumonia, encephalitis (inflammation of the brain), and, rarely, death. Young children, individuals with compromised immune systems (due to conditions like cancer treatment or HIV/AIDS), and pregnant women are particularly susceptible to severe outcomes. A DPHHS report released last year highlighted a concerning increase in cases of secondary bacterial pneumonia following measles infection, even in previously healthy individuals. This necessitates proactive vaccination to protect both individuals and the healthcare system.

Contact Tracing and Containment Efforts

The DPHHS is actively engaged in contact tracing to identify and notify individuals who may have been exposed to the virus. This is a laborious process that requires meticulous investigation to determine potential contacts and assess their vaccination status. Teams are working to ensure exposed, unvaccinated individuals are offered post-exposure prophylaxis - typically the measles vaccine itself, if administered within 72 hours of exposure - to mitigate the risk of infection.

The department is also collaborating with local healthcare providers, schools, and community organizations to disseminate information about measles, vaccination, and symptom recognition. Public service announcements are running on local television and radio stations, and social media campaigns are being utilized to reach a wider audience. The state is also considering the implementation of temporary vaccination clinics in affected areas to increase accessibility.

National Context and Global Trends

The Montana outbreak occurs within a broader national and global context of rising measles cases. The World Health Organization (WHO) has repeatedly warned of a resurgence in measles worldwide, largely driven by declining vaccination rates and disruptions to immunization programs caused by conflicts and the COVID-19 pandemic. The United States saw a significant increase in measles cases in 2019, and while numbers dipped during the pandemic, they are now trending upwards again. This underscores the importance of maintaining high vaccination coverage not only locally but also nationally and globally to prevent the re-establishment of measles as a common disease.

Resources and Information

Individuals concerned about measles or their vaccination status are encouraged to consult their healthcare provider or visit the DPHHS website at [ https://dphhs.mt.gov/publichealth/immunization ] for more information. The website provides comprehensive details about measles, vaccination recommendations, and locations for finding vaccination services. The CDC's website ([ https://www.cdc.gov/measles/index.html ]) also offers valuable resources and updates on the national measles situation.
