Norovirus: The Highly Contagious Stomach Bug Sweeping Across the Northeast
Published Feb. 23, 2024, 4:15 p.m. ET
Spread of the Norovirus
The Northeast region, particularly Pennsylvania, New Jersey, and New York, is experiencing the highest positivity rate for the hypervirulent strain of the norovirus, according to the U.S. Centers for Disease Control and Prevention (CDC). The region recorded a staggering 14% of swab tests coming back positive for the gastrointestinal ailment at the beginning of February.
Alarming Symptoms
The norovirus, being a highly contagious and hypercontagious stomach bug, causes a range of alarming symptoms including violent diarrhea, stomach pain, and vomiting. Sufferers may face significant fluid loss and eventual dehydration.
Insidious Nature of Norovirus
The norovirus is particularly insidious due to its easy transmission from person to person. It takes only a few particles to make someone sick, and infectees often remain contagious for weeks even after symptoms improve. Children, in particular, facilitate the spread of the contagion, contributing to the closure of schools and day-care centers in the Northeast.
Prevention and Mitigation
Preventing the spread of the norovirus can be achieved by rinsing fruits and vegetables, thoroughly cooking shellfish, and most importantly, washing hands with soap and water. Unlike some other bugs, the norovirus is resistant to hand sanitizers. Those infected are advised to stay home, avoid preparing food for others, and stay hydrated to mitigate the severity of symptoms.
Rising National Numbers and Seasonality
While the Northeast shows the highest positivity rate, the norovirus cases are also on the rise nationwide, with a 12% increase in positive tests since November. Norovirus cases generally spike around February and March, when people are more likely to be indoors and in close proximity to one another.
