Norovirus Outbreak: A Growing Concern in New Jersey and Nationwide
There’s an alarming outbreak causing concern among health officials in New Jersey, as norovirus has been spreading rapidly — and doctors say it is highly contagious.
Norovirus Symptoms
Norovirus symptoms typically begin 12 to 48 hours after exposure to the virus, per the CDC. These are often sudden and "explosive," says Schaffner.
- Diarrhea
- Vomiting
- Abdominal pain or cramps
- Nausea
People often vomit or have diarrhea many times, and these can happen simultaneously, says Schaffner.
How Long Does Norovirus Last?
Norovirus symptoms typically last one to three days, and most people will recover on their own completely. “People get over this after a few days of being miserable,” says Schaffner.
Is Norovirus Deadly?
In most cases, norovirus is not life-threatening and deaths are rare, especially in the U.S. However, it can cause severe disease and complications. “The concern is always dehydration because of the fluid loss through vomiting and through diarrhea," says Schaffner.
How Does Norovirus Spread?
Norovirus spreads between people very easily. "It’s an extraordinarily communicable, transmissible virus," says Schaffner.
Transmission of norovirus may occur through:
- Direct contact with a sick person
- Sharing food or utensils with a sick person
- Consuming food or drinks contaminated with the virus
- Touching contaminated surfaces then touching your mouth
- Inhaling aerosols from a sick person’s vomit
How Long is Norovirus Contagious?
Norovirus is contagious from the moment symptoms begin until at least a few days after symptoms resolve. People infected with norovirus can shed the virus even after they recover, says Schaffner. It’s possible to spread norovirus to others for two weeks or more after you feel better, per the CDC.
Norovirus Treatment
There’s no specific antiviral treatment for norovirus, says Schaffner.
Norovirus will typically resolve on its own, but rest and supportive care can help manage symptoms. Rehydration is key, Schaffner notes. Drinking water, sports drinks and oral rehydration solutions can help replenish fluids lost during diarrhea and vomiting.
How to Prevent Norovirus
There is no vaccine available against norovirus, says Schaffner, but there is ongoing research to develop one.
In the meantime, you can take the following actions to protect yourself and others against norovirus, according to experts:
- Wash your hands often
- Cook shellfish thoroughly
- Stay home when sick
- Avoid cooking for others while sick
- Disinfect contaminated surfaces with a bleach solution
- Launder soiled bedding or clothes on high heat
Conclusion
Norovirus is a growing concern in New Jersey and nationwide, with a 350% increase in reported cases over the past year. It’s essential to take preventative measures to avoid spreading the virus, especially among high-risk individuals. By understanding the symptoms, transmission, and prevention methods, we can take control of this outbreak and reduce its impact.
