In a troubling development, a Suffolk County infant has been diagnosed with measles after contracting the virus during an overseas trip. The child was too young to be vaccinated and has since been discharged from the hospital, with health officials reporting that the infant is recovering at home.

Health authorities are actively monitoring at least 12 residents who may have been exposed while visiting Cohen Children's Medical Center in New Hyde Park during a critical window from March 3 to March 6. Among those monitored, eleven have been vaccinated. The twelfth individual, also an infant who is too young for the standard measles vaccine, received immune globulin treatment—a measure that can help prevent the illness post-exposure. This baby is currently under quarantine to ensure safety.

The Nassau County Health Department has also stepped in, tracking local residents who might have encountered the virus at the same medical facility, although they have not disclosed how many individuals are involved.

The last reported case of measles on Long Island occurred in March 2024 involving a child under five from Nassau County, who experienced a full recovery. In 2019, the area recorded multiple cases, indicating that the threat of measles remains significant.

Dr. Aleena Zahra, an infectious disease specialist at St. Catherine of Siena Hospital, emphasized the risks posed by measles, particularly for young children. Complications can include pneumonia, severe ear infections, and potentially dangerous brain inflammation known as encephalitis. "The risk increases substantially in children under the age of 5," she cautioned.

Why should parents be particularly concerned now? Prior to the introduction of the measles vaccine in 1963, the disease claimed up to 500 lives annually in the U.S., with tens of thousands hospitalized. Healthy vaccination practices have dramatically altered these statistics, but the risk persists, especially as many infants remain unvaccinated until they are 12 to 15 months old.

Dr. Zahra noted that in certain circumstances, young infants may receive an early vaccination if traveling internationally or during an active outbreak situation.

The recent Suffolk County measles case marks the third infection reported statewide this year and the first outside of New York City. Dr. Gregson Pigott, Suffolk County Health Commissioner, confirmed that exposures were limited to the child's family, as the infant was not involved in any community gatherings or educational settings that would risk wider transmission.

It’s important to note that this case is not linked to larger outbreaks occurring in other U.S. regions, particularly Texas, which is currently facing a measles crisis with over 223 confirmed cases, including a tragic case of a school-aged child who died from the virus after not being vaccinated.

Symptoms of measles typically manifest 10 to 12 days after exposure. Initial signs include high fever, coughing, and a runny nose, followed by the appearance of distinctive white spots in the mouth—known as Koplik spots—and then a characteristic red rash that spreads across the body.

Health officials urge anyone who may have been in the pediatric emergency department at Cohen's on March 3 or 4, or who visited a child in the Medicine 3 unit between March 3 and 6, to seek immediate medical attention if exhibiting symptoms or have concerns about potential exposure.

The hospital is aligning with health authorities to ensure all precautionary measures are taken to prevent any further cases, engaging in thorough exposure protocols. As this public health situation unfolds, continued vigilance and awareness remain crucial. Are you and your loved ones protected against measles? Don’t wait—check your vaccination status today!
