Trenton, NJ - March 27th, 2026 - Health officials in New Jersey are on alert after the detection of measles virus RNA in wastewater samples from Bergen and Hudson Counties. This marks the second time this year that the virus has been identified in the state's wastewater system, raising concerns about potential community spread and mirroring a worrying trend seen nationally and internationally. The New Jersey Department of Health (NJDOH) announced the findings Tuesday, urging unvaccinated individuals to take preventative measures.

While no confirmed cases of measles have been reported directly linked to these wastewater detections, the presence of viral RNA serves as a critical early warning system. This indicates that an infected individual or individuals are likely shedding the virus within these communities, even before symptomatic cases manifest. The virus is being excreted in stool and entering the sewage system, a phenomenon increasingly utilized by public health agencies for proactive disease surveillance.

Wastewater Surveillance: A New Frontier in Public Health

The use of wastewater surveillance has gained prominence since the COVID-19 pandemic, demonstrating its effectiveness in tracking infectious disease prevalence. This method offers a non-invasive way to monitor community health, identify outbreaks before they escalate, and target vaccination efforts. Detecting viral RNA in wastewater doesn't pinpoint the exact number of infected individuals, but it provides crucial insight into the virus's presence and potential circulation within a defined area.

"This isn't just a New Jersey issue," explains Dr. Evelyn Reed, a leading epidemiologist at Rutgers University. "We're seeing a global resurgence of measles, fueled by declining vaccination rates and increased travel. Wastewater monitoring is proving to be an invaluable tool in detecting these subtle shifts in disease activity." The first detection in New Jersey occurred in Passaic County in February, highlighting the need for sustained and expanded surveillance efforts.

Measles: A Highly Contagious and Potentially Severe Disease

Measles remains a significant public health threat due to its extreme contagiousness. It's spread through respiratory droplets released when an infected person coughs or sneezes - making it easily transmitted in crowded settings. Symptoms typically begin with a high fever, persistent cough, runny nose, and conjunctivitis (red, watery eyes). A characteristic rash then appears, usually starting on the face and spreading throughout the body.

However, measles isn't just a fever and rash. It can lead to severe complications, particularly in young children and immunocompromised individuals. These complications include pneumonia, encephalitis (inflammation of the brain), and, in rare cases, death. Approximately 1 in 5 people who contract measles require hospitalization.

Vaccination: The Primary Defense

The highly effective measles, mumps, and rubella (MMR) vaccine is the cornerstone of measles prevention. The Centers for Disease Control and Prevention (CDC) recommends that children receive two doses of the MMR vaccine: the first between 12 and 15 months of age, and the second between 4 and 6 years of age. Adults born in 1957 or later who have not had measles or been vaccinated are also advised to get vaccinated.

The recent increase in measles cases is directly linked to a decline in MMR vaccination rates. Vaccine hesitancy, misinformation, and disruptions to healthcare services during the pandemic have all contributed to this concerning trend. The World Health Organization (WHO) has warned that the global measles elimination goals are at risk.

What Should You Do?

The NJDOH is urging all residents, especially those who are unvaccinated or unsure of their vaccination status, to contact their healthcare provider to schedule an MMR vaccine. Those who may have been exposed to measles, especially if they are experiencing symptoms, should also seek medical attention.

Health officials also recommend practicing good hygiene, such as frequent handwashing and covering coughs and sneezes. Individuals traveling internationally should ensure they are fully vaccinated against measles, as the virus remains prevalent in many parts of the world.

The NJDOH is continuing to monitor wastewater samples throughout the state and will provide updates as more information becomes available. This proactive approach is essential to protecting New Jersey communities from a potential measles outbreak and contributing to the broader national effort to control this dangerous, yet preventable, disease.
