What is Norovirus? Kerala confirms two cases; Check symptoms, causes

The name "norovirus" refers to a family of viruses that can cause violent vomiting and diarrhoea. It is widespread and is contagious. It can spread through infected people, contaminated food, or contaminated surfaces. Norovirus is also known as the winter vomiting bug. Although many refer to norovirus as "the stomach flu," it has nothing to do with the flu (influenza). According to the World Health Organization (WHO), an estimated 685 million (68.5 crore) cases of norovirus are recorded every year globally — including 200 million (20 crore) among children under 5. It causes an estimated 200,000 deaths a year — including 50,000 children. The casualties are higher in low-income countries.

Causes of Norovirus?

The norovirus can spread to people in many different ways. Close contact with an infected person, touching your mouth after touching contaminated surfaces, or consuming tainted food or water are all ways to contract the virus. In the US, norovirus is the most common food-borne sickness culprit. Noroviruses are challenging to eradicate since they are resistant to both high and low temperatures as well as numerous disinfectants.

Here are some of the common causes of Norovirus:

1. Drinking contaminated water

2. Eating contaminated food

3. Touching your hand to your mouth after your hand has been in contact with a contaminated surface or object

4. Being in close contact with a person who has norovirus infection
