Northern Nevada Public Health (NNPH) has confirmed the first case of measles in Washoe County since April 2018, prompting a public health response and renewed calls for vaccination. The case, identified on Friday, December 26, 2025, involves an unvaccinated adult male who has been hospitalized.
Why did measles return? The return of measles is linked to declining vaccination rates, both locally and globally, allowing the highly contagious virus to re-emerge. Travel and community spread contribute to outbreaks.
Public Health Response Underway
NNPH is actively investigating the case and following up with individuals who may have had close contact with the patient. While the source of the infection remains unknown, initial reports indicate the individual remained at home while contagious, potentially limiting broader community exposure.
“NNPH found out today that a resident tested positive for measles and it was imperative that we notify the public instantly,” stated Dr. Chad Kingsley, District Health Officer for NNPH.”Our staff is working to gather more details to help minimize any spread. In the meantime, we advise that people monitor any symptoms for measles, check their vaccine status, and, if necessary, contact any medical provider before visiting with any medical-related questions.”
The health agency emphasized its commitment to protecting patient privacy while also prioritizing public safety.further information will be released if the investigation reveals a broader public health impact.
Who was affected? The initial case involves an unvaccinated adult male hospitalized in Washoe County. Public health officials are working to identify and contact individuals who may have been exposed.
Understanding the Threat of Measles
Measles is a highly contagious viral illness that can lead to serious complications, including hospitalization and, in rare cases, death. Certain populations are at increased risk of severe illness, including children, pregnant women, and individuals with compromised immune systems.
The virus is transmitted thru the air and can remain infectious for up to two hours after an infected person leaves a space. Symptoms typically appear within seven to 21 days of exposure and include:
- Fever
- Cough
- Runny nose
- Red eyes
- A rash that usually develops one to four days after initial symptoms.
individuals experiencing these symptoms are urged to stay home, avoid public gatherings, and contact their healthcare provider before seeking medical attention to allow for appropriate precautions.
What is being done? NNPH is conducting contact tracing, monitoring for additional cases, and urging residents to check their vaccination status.The agency is also providing information to healthcare providers.
Vaccination Remains the Best Defense
The measles, mumps, and rubella (MMR) vaccine is remarkably effective in preventing measles. two doses of the MMR vaccine provide approximately 97 percent protection against the illness. public health officials strongly encourage all residents to review their vaccination records and ensure they are up-to-date.
NNPH continues to monitor all communicable diseases within Washoe County and collaborate with healthcare providers to ensure proper testing and adherence to safety protocols. Updates will be shared on the agency’s website and social media channels as the investigation progresses.
How did it end (as of this report)? As of December 26, 2025, the situation is ongoing. The investigation is in its early stages,with NNPH actively working to contain the spread and determine the source of the infection. No further cases have been confirmed at the time of this report.
