Understanding Norovirus: What You Need to Know

What is Norovirus?

Norovirus is a highly contagious gastrointestinal virus that can spread quickly through contaminated food, water, and surfaces. It causes inflammation of the stomach and intestines, leading to symptoms like nausea, diarrhea, and vomiting[2].

What is the ‘Kawasaki’ Norovirus Strain?

The ‘Kawasaki’ norovirus strain, also known as the GII.17 genotype, has been detected in the UK. This strain was first identified in Kawasaki, Japan in 2014 and has now seen an increase in cases since June 2024[1][3].

Symptoms of Norovirus

The main symptoms of norovirus include:

  • Nausea
  • Diarrhea
  • Vomiting
  • Fever (up to 39°C)
  • Headache
  • Muscle aches

Symptoms typically develop 12 to 48 hours after exposure and last for about two to three days[2][3].

How is Norovirus Spread?

  • Direct Contact: Through physical contact with an infected person.
  • Contaminated Food: Food prepared by someone with the virus.
  • Contaminated Surfaces: By touching contaminated surfaces or objects and then touching your mouth[3].

How Can You Prevent Catching Norovirus?

To prevent norovirus, you should:

  • Practice Hand Hygiene: Wash hands frequently with soap and warm water, especially after using the bathroom, before eating, and after cleaning up vomit or diarrhea.
  • Avoid Sharing Food: Refrain from sharing food, drinks, or utensils.
  • Clean Surfaces: Use bleach-based household cleaners to disinfect surfaces.

It’s crucial to stay home for at least 48 hours after symptoms stop to prevent further transmission[2][3].

Treating Norovirus

Since antibiotics don’t work on norovirus, treatment focuses on hydration:

  • Drink Fluids: Consume plenty of fluids with electrolytes to balance your body’s salts.
  • Rest and Plain Foods: Get plenty of rest and eat plain foods like bread or rice.

If symptoms persist or worsen, call 111 for medical advice. Severe cases require a hospital visit[2][3].

By following these guidelines, you can reduce your risk of catching norovirus and help prevent its spread.
