Long Island residents are experiencing a surge in stomach virus cases, impacting households and schools with symptoms like nausea, vomiting, stomach cramping, and diarrhea. While these illnesses are common during the colder months, health providers are particularly concerned about potential dehydration, especially among young children and the elderly.
The current outbreak, largely attributed to the highly contagious norovirus, is causing widespread discomfort and disruption. Wastewater monitoring across the Northeast indicates a high level of norovirus activity, suggesting a broader regional trend. Understanding how this virus spreads and taking preventative measures are crucial to protecting yourself and your family.
Norovirus is known for its resilience and ease of transmission. According to the Centers for Disease Control and Prevention (CDC), it causes an estimated 19 to 21 million illnesses and 900 deaths annually in the United States, with those over 65 being disproportionately affected .
“Hand-washing, hand-washing, hand-washing,” emphasizes Dr. David Fagan, a pediatrician at Northwell Health, highlighting the most effective preventative measure. He notes that alcohol-based hand sanitizers are less effective against norovirus due to the virus’s robust outer coating .
Understanding Norovirus and Its Spread
Norovirus, often called the “stomach flu,” is a viral infection affecting the stomach and intestines. It’s highly contagious and can be contracted through contaminated surfaces, food, or water handled by an infected person. The virus is linked to over 50% of food poisoning cases in the U.S. . Symptoms typically appear one to three days after infection and can last up to 14 days, including nausea, stomach cramping, vomiting, and diarrhea .
While testing isn’t routinely performed unless hospitalization is required, clinicians are observing cases of norovirus alongside other viruses causing similar symptoms. A new strain, GII.17, became dominant during the 2024-25 season, causing 75 percent of outbreaks, a significant increase from previous years .
Protecting Your Family and Managing Symptoms
Preventing the spread of norovirus requires diligent hygiene practices. Dr. Christine Doucet, owner of Patchogue Family Medical Care, advises regularly wiping down frequently touched surfaces like counters and doorknobs. “We have families where everybody got it because it ran through the entire house,” she explains .
Treatment focuses on managing symptoms and preventing dehydration. Dr. Eve Meltzer Krief of Huntington Village Pediatrics stresses the importance of fluid intake, particularly for infants and young children, recommending electrolyte replacement drinks like Pedialyte. She advises parents to contact their doctor if a child experiences ongoing vomiting .
For those experiencing symptoms, Dr. Doucet recommends waiting an hour after the last vomiting episode before consuming fluids, starting with small, teaspoon-sized doses every 15 minutes. After a few hours, bland foods like toast and crackers can be introduced. Seniors with heart conditions should exercise caution with electrolyte drinks due to their sugar and sodium content and may require IV rehydration at a hospital .
Monitoring hydration levels is crucial, especially in children. Parents should ensure adequate urination and clear urine color. For infants, diaper checks are essential. “If there is decreased urination or lethargy or if they are having trouble keeping down small sips, let your child’s doctor know,” advises Dr. Meltzer Krief .
What to Expect Moving Forward
Health officials continue to monitor the spread of norovirus and emerging strains. The current surge underscores the importance of consistent hygiene practices, particularly handwashing, to mitigate transmission. As the virus typically peaks between November and April, continued vigilance is advised throughout the winter months. Staying informed about symptoms and seeking medical attention when necessary will be key to navigating this outbreak.
