TRENTON, NJ - February 2nd, 2026 - New Jersey health officials have confirmed a concerning surge in measles cases, reaching a 33-year high, sparking fears of a wider outbreak and prompting a renewed call for vaccination across the state. As of Thursday, February 1st, 2026, the New Jersey Department of Health (NJDOH) reported 21 confirmed cases across 12 counties, a figure not seen since 1991. This resurgence isn't isolated to the Garden State, mirroring a national trend that public health experts warn could unravel decades of progress towards measles eradication.

Dr. Kaitlin Jenkins, New Jersey's State Epidemiologist, emphasized the critical need for public awareness and preventative measures. "Measles is exceptionally contagious - far more so than COVID-19," she stated in a press conference earlier today. "A single infected individual can transmit the virus to up to 90% of those who are not immune. We must act swiftly to protect our communities."

The NJDOH has categorized counties by risk level, informing residents about localized threat levels. Currently:

• High Risk: Atlantic, Bergen, Essex, Hudson, Mercer, Middlesex, Monmouth, Ocean, Passaic, Union - These counties exhibit a combination of lower vaccination rates and/or higher rates of international travel, creating optimal conditions for transmission.
• Moderate Risk: Burlington, Camden, Cape May, Cumberland, Gloucester, Salem, Somerset, Sussex, Taylor - These areas require increased vigilance, with officials monitoring for potential spread.
• Low Risk: Hunterdon, Morris, Warren - While currently at lower risk, health officials stress that maintaining high vaccination rates is crucial to prevent future outbreaks in these regions.

Beyond New Jersey: A National Trend

The spike in New Jersey cases is part of a disturbing national pattern. The CDC has reported a significant increase in measles cases nationwide in the past year, attributed to several factors. Declining vaccination rates, particularly among young children, coupled with increased international travel and waning public immunity, have created a fertile ground for the virus to spread. The CDC reports that the U.S. lost its measles elimination status in 2019, and the current trend suggests a continued struggle to regain that status.

Understanding Measles: Symptoms and Transmission The measles virus is airborne and spreads easily through respiratory droplets produced when an infected person coughs or sneezes. Initial symptoms, appearing roughly 10-14 days after exposure, include high fever, persistent cough, runny nose, and conjunctivitis (red, watery eyes). This is followed by the characteristic measles rash, which typically starts on the face and spreads throughout the body. Complications can be severe, including pneumonia, encephalitis (brain swelling), and even death.

Vaccination: The Cornerstone of Prevention The MMR (measles, mumps, and rubella) vaccine remains the most effective defense against measles. The CDC recommends that children receive two doses: the first between 12 and 15 months, and the second between 4 and 6 years. Adults who were born in 1957 or later and have not had measles or the vaccine are also advised to get vaccinated. Public health officials are urging parents to review their children's vaccination records and schedule appointments if necessary. Furthermore, emphasis is being placed on ensuring access to vaccination for underserved communities.

Public Health Response and Future Steps The NJDOH is collaborating closely with local health departments to rapidly identify and isolate confirmed cases, conduct contact tracing, and implement targeted vaccination campaigns. These campaigns will prioritize high-risk communities and focus on addressing vaccine hesitancy through education and outreach. Dr. Jenkins also highlighted the importance of international cooperation. "Measles doesn't respect borders. We need coordinated global efforts to control outbreaks and prevent the virus from spreading further," she said.

The department has also established a dedicated hotline to address public inquiries and concerns. The coming weeks will be critical in determining whether New Jersey can contain this outbreak and prevent a wider public health crisis.
