Norovirus Cases Surge in NYC

New York City saw a dramatic spike in norovirus cases in December, with nearly 1,300 reported—almost triple the number from the same period in 2023. This highly contagious virus causes vomiting, diarrhea, stomach pain, and other unpleasant symptoms. There's no antiviral treatment, and it can linger on surfaces for weeks.

Understanding Norovirus

Symptoms appear quickly and can be severe. Dehydration is a major concern, especially for young children and the elderly.

Transmission occurs through contact with infected individuals, contaminated food and water, and unclean surfaces. The virus is incredibly resilient, surviving on various surfaces for extended periods.

Prevention is Key

The most effective way to prevent infection is diligent handwashing with soap and water for at least 20 seconds, especially before eating and after using the bathroom. Avoid contaminated food, thoroughly wash fruits and vegetables, and don't rely on hand sanitizers, as they are ineffective against norovirus. A bleach solution is recommended for disinfecting surfaces in affected households.

If you experience symptoms, stay home for at least two days after they subside, as you could still be contagious for several days or even weeks.

Expert Insights

Doctors emphasize the importance of staying hydrated and avoiding contaminated food or surfaces to prevent infection. They also stress the need for thorough cleaning with bleach, not just alcohol-based disinfectants.
