Lancaster County Confirms First Measles Case in 90 Years
Locales: Pennsylvania, UNITED STATES

LANCASTER, Pa. - February 10th, 2026 - Lancaster County health officials have confirmed the first case of measles within the county since 1936, sparking concerns about a potential resurgence of the highly contagious viral disease. The individual affected was unvaccinated and is currently isolated while recovering. Public health authorities are diligently working to trace contacts and assess potential exposure risks within the community.
This case isn't an isolated incident. It arrives amidst a worrying national trend of increasing measles cases, particularly in communities with lower vaccination rates. While the Centers for Disease Control and Prevention (CDC) declared measles eliminated in the U.S. in 2000, that status is increasingly threatened. Sporadic outbreaks have been occurring with greater frequency in recent years, and this Lancaster County case may signal a more widespread return of the disease.
"This case serves as a stark reminder of the critical importance of vaccination, not just for individual protection, but for the collective health of our community," stated Dr. Michael Leonard, medical director for the Lancaster County Department of Health. "Measles is extraordinarily contagious - far more so than many people realize. A single infected person can easily spread the virus to numerous others, leading to outbreaks that overwhelm healthcare systems and put vulnerable populations at risk."
Understanding the Threat: Measles and its Complications
Measles, also known as rubeola, is a viral illness characterized by fever, rash, cough, runny nose, and conjunctivitis (red, watery eyes). While often considered a childhood disease, measles can affect people of all ages. The virus spreads through the air when an infected person coughs or sneezes. It's so contagious that if one person has measles, 90% of those who are not immune will catch the disease if exposed.
Beyond the uncomfortable symptoms, measles can lead to serious and potentially life-threatening complications, especially in young children, pregnant women, and individuals with weakened immune systems. These complications include pneumonia, encephalitis (inflammation of the brain), seizures, and even death. In rare cases, a delayed complication called subacute sclerosing panencephalitis (SSPE) can develop years after the initial infection, causing progressive neurological damage.
Vaccination: The Most Effective Defense
The measles-mumps-rubella (MMR) vaccine is a safe and highly effective way to prevent measles. The CDC recommends that children receive two doses of the MMR vaccine: the first dose between 12 and 15 months of age, and the second dose between 4 and 6 years of age. Adults born in 1957 or later who have not had measles or been vaccinated should also receive two doses of the MMR vaccine.
"The MMR vaccine has a long and well-documented history of safety and efficacy," explains Dr. Eleanor Vance, an epidemiologist specializing in infectious diseases. "It's one of the most successful vaccines we have, and it's responsible for the dramatic decline in measles cases we saw before recent years. However, the vaccine only works if people actually receive it."
Declining Vaccination Rates: A Growing Concern
Health officials attribute the recent increase in measles cases to declining vaccination rates. Several factors contribute to this trend, including vaccine hesitancy fueled by misinformation, access barriers to healthcare, and complacency among those who believe measles is no longer a threat. The spread of false information online and through social media has played a significant role in eroding public trust in vaccines.
Lancaster County, like many communities across the nation, has seen a slight decrease in MMR vaccination coverage rates among children in recent years. This drop, while seemingly small, can have a significant impact on herd immunity - the level of protection needed to prevent the spread of disease within a population. When vaccination rates fall below the threshold for herd immunity, outbreaks become more likely.
County Response and Public Guidance
The Lancaster County Department of Health is urging residents to check their vaccination records and ensure they are up to date on the MMR vaccine. They are also actively investigating the current case to identify and notify anyone who may have been exposed. Individuals who experience measles-like symptoms are advised to contact their healthcare provider immediately before visiting a medical facility to prevent further spread of the virus.
The department is also planning a public awareness campaign to educate residents about the importance of vaccination and address common misconceptions about measles and the MMR vaccine. They're partnering with local schools, community organizations, and healthcare providers to reach a wider audience and promote vaccine confidence. This case serves as a critical wake-up call: protecting our community from preventable diseases requires ongoing vigilance and a commitment to public health.
