IMMEDIATE RELEASE
June 11, 2025
HOLBROOK, AZ — The Navajo County Public Health Services District (NCPHSD), in coordination with the Arizona Department of Health Services (ADHS), continues to monitor four confirmed measles cases reported in Navajo County. At this time there are no new cases to report.
The original cases, identified earlier this week, involved individuals who were not immunized and had recent international travel history. All four individuals were exposed through a single source, and these remain the only confirmed measles cases in both Navajo County and the State of Arizona in 2025.
NCPHSD continues to work closely with ADHS and healthcare partners to monitor these cases and provide necessary support.
What You Need to Know About Measles and Immunity
Measles is a highly contagious viral disease that can lead to serious health complications, particularly in young children, pregnant individuals, and those with weakened immune systems. The most effective protection against measles is the MMR (measles, mumps, and rubella) immunization.
Individuals who are uncertain about their immunity can request a measles titer test from their healthcare provider or the Navajo County Public Health Services District. A titer test is a simple blood test that measures the presence and level of measles-specific antibodies in the blood. If the test shows a positive (protective) antibody level, it indicates that the individual is immune, either due to prior immunization or past infection. If the result is negative or unclear, the person may not be fully protected and should consider getting immunized.
Titer tests are especially useful for:
- Adults who do not have access to their immunization records,
- Students or employees who must verify immunity for school or work,
- Travelers heading to countries with ongoing outbreaks,
- Healthcare workers and first responders,
- Individuals with special medical circumstances who require immunity confirmation.
Titer testing offers a safe and reliable way to confirm protection without unnecessary reimmunization. Most healthcare providers and laboratories offer this service, and it may be covered by insurance depending on the circumstances.
What You Can Do
- Check your immunization status. Talk to your healthcare provider about your immunization history or getting a titer test.
- Stay informed. Follow updates from NCPHSD and ADHS for the latest public health guidance.
- Protect your community. Measles is preventable. Immunization and immunity testing are key tools in stopping its spread.
NCPHSD remains committed to protecting the health and safety of all Navajo County residents and encourages everyone to take proactive steps to ensure they are protected against immunization-preventable diseases.
