The news of the Norovirus outbreak has been in circulation for some time now. The outbreak has been on the global scale mostly, but recently it has hit close to home with two confirmed cases of Norovirus infection in Kerala, as of January 24th reports. With so much attention given to this virus, it is important to understand what the virus is capable of doing in order to be able to fight it better.
Firstly, norovirus is not a new virus and it has been circulating among us for nearly half a century now. Secondly, the virus is held to be one of the causes of gastroenteritis or stomach flu. Thirdly, norovirus is capable of surviving in cold temperatures, so it is more common in cold countries and during the winter months. As per another report, it was found that the norovirus infection was more noticeable in high-income countries. In India, however, cases were reported in shared food environments, such as hostels and schools.
With cases gradually on the rise in India, let us explore a little more details about the norovirus infection so that we are able to tackle the infection as aware citizens.
In the opinion of experts, the infection has a high possibility of spreading in crowded and closed spaces where there is close contact with a person who is infected with the virus. Even after the infected person has left the spot, the virus continues to thrive on objects and surfaces for weeks and days. Some other causes of the norovirus are:
The symptoms usually start suddenly and can include the following:
· Loose or watery diarrhoea
· Cramps or stomach pain
· Feeling unwell
· Muscle pain
· Low-grade fever
· Nausea
· Vomiting
You are likely to experience symptoms 12-48 hours post your exposure to the norovirus infection. In some cases, the infected person may appear asymptomatic (not showing any signs at all). However, they are still highly contagious and can spread the infection to others when in contact.
Sometimes norovirus causes no symptoms, but infected people can still pass the virus to others. A child with a norovirus infection who has a lot of diarrhea and vomiting can get dehydrated and feel lightheaded or dizzy.

Norovirus infection can clear up in a few days and is not usually life-threatening. But in young children, older adults, pregnant women and those with a weak immune system, the effects of the infection can be severe and even pose a risk to someone’s life. Some warning indications are listed below:
· Listlessness
· Dry throat and mouth
· Decrease in the output of urine
· Dizziness
· Fatigue
Knowing your risk factors can keep you protected from falling ill and suffering from uncomfortable symptoms.
There is no mystery about the fact that norovirus can cause a highly contagious infection. The only way to keep yourself safe is by practising safe hygiene habits:
In order to prevent the virus from spreading if you have already been infected, here is what you should do:
The article helps us to understand the various aspects of norovirus infection and we can gather that by following a few preventive steps, we can keep ourselves protected and stop the spread. If you develop symptoms of persistent diarrhoea, along with severe dehydration, you must contact your doctor right away, start your treatment and take adequate rest at home to maintain isolation for at least one week. Among other things, you can spread your knowledge about the virus amongst your loved ones and collectively stay vigilant.
