Norovirus Cases in Kerala


Norovirus cases have been reported for the first time in India from Kerala. 


Norovirus causes inflammation of the stomach or intestines. This is called acute gastroenteritis. A person usually develops symptoms 12 to 48 hours after being exposed to norovirus.

However, most people with norovirus illness get better within 1 to 3 days.

Spread easily:

  • People infected with Norovirus can shed billions of norovirus particles in the environment through feces or vomit and only a few virus particles can make other people sick.


  • Having direct contact with the infected person.
  • Consuming contaminated food or water.
  • Touching contaminated surfaces
  • Infection usually occurs in closed and crowded environments.


The most common symptoms of Norovirus are

  • Diarrohea
  • Vomiting
  • Nausea
  • Stomach Pain

Along with other symptoms like: fever, body ache and headache.

Its other name 

  • Norovirus was originally called the “Norwalk virus”. It is named after the town Norwalk, in the Ohio state of the United States where it was first detected in 1972.
  • Although norovirus can strike year-round, it’s more common in the winter, that’s why it is sometimes called “winter vomiting bug.” 
  • Noroviruses also are “sometimes called food poisoning”, because they can be transmitted through contaminated food or water.
