Measles Case Confirmed in Washtenaw County
Locales: Michigan, UNITED STATES

Ann Arbor, Michigan - March 13th, 2026 - Washtenaw County health officials confirmed a second case of measles today, triggering an urgent public health response and a renewed call for vaccination. The Washtenaw County Health Department (WCHD) is actively investigating the new case and working to trace potential contacts, building upon efforts initiated with the first confirmed case earlier this week. The affected individual is currently isolating at home to prevent further spread.
This development, while concerning, isn't entirely unexpected given the broader national and global landscape of infectious disease. While measles was declared eradicated in the United States in 2000, imported cases - often linked to international travel - continue to pose a risk, and outbreaks, though infrequent, are becoming more common. Health experts attribute this resurgence to declining vaccination rates in certain communities, creating pockets of susceptibility.
Measles is a highly contagious viral disease spread through respiratory droplets produced when an infected person coughs or sneezes. It's so contagious that if one person with measles enters a room full of unvaccinated individuals, nearly 90% of those people will become infected. Symptoms typically appear 2-3 weeks after exposure and begin with fever, cough, runny nose, and conjunctivitis (red, watery eyes). A characteristic rash follows, often starting on the face and spreading throughout the body. While many people recover from measles, it can lead to serious complications, especially in vulnerable populations.
"We are deeply concerned about this second case," stated Dr. Juan C. Triana, Medical Director for the WCHD. "It underscores the ongoing threat of measles transmission within our community. Measles isn't simply a childhood illness; it's a serious health risk with potentially devastating consequences, particularly for infants, young children, pregnant individuals, and those with compromised immune systems. Vaccination remains the single most effective way to protect ourselves and our loved ones."
The WCHD is urging all residents to review their vaccination records and ensure they are up-to-date on the measles, mumps, and rubella (MMR) vaccine. Two doses of the MMR vaccine are recommended for most individuals, with the first dose typically administered between 12-15 months of age and the second between 4-6 years of age. Infants too young to receive the vaccine are particularly vulnerable, as are individuals with conditions that weaken their immune systems, such as those undergoing cancer treatment or living with HIV/AIDS.
Beyond vaccination, the WCHD is emphasizing the importance of proactive measures to prevent the spread of infection. Individuals experiencing measles-like symptoms are advised to stay home and contact their healthcare provider before seeking medical attention, allowing the provider to take appropriate precautions to prevent potential exposure in the waiting room. The health department is also actively investigating potential exposure sites linked to the confirmed cases, including schools, childcare facilities, and public transportation.
The recent cases in Washtenaw County are part of a worrying national trend. The CDC reported a significant increase in measles cases in 2024 and 2025, with several outbreaks occurring in states with lower vaccination coverage rates. Experts predict that if vaccination rates continue to decline, measles could become re-established as a common childhood disease, reversing decades of progress in eliminating this potentially life-threatening illness.
The WCHD encourages anyone who believes they may have been exposed to measles to contact their healthcare provider or the health department immediately for guidance and potential testing. Further information on measles, vaccination schedules, and outbreak updates can be found on the WCHD website ([ https://www.ewashtenaw.org/government/departments/community-health/epidemiology/measles ]) and the CDC website ([ https://www.cdc.gov/measles/index.html ]).
The health department will be holding a community information session next week to address concerns and answer questions regarding the recent cases and the importance of measles vaccination. Details about the session will be announced on the WCHD website and social media channels.
