As the colder weather approaches, some bugs and viruses are more common, including norovirus.

Whether you know someone who has suffered from norovirus or it's the first time you've come across it, you might be wondering what it is and the symptoms you'll need to look out for.

To help you further understand the vomiting bug, here's what we know.

What is norovirus?

Also known as the "winter vomiting bug", norovirus is a stomach bug which can cause diarrhoea and vomiting.

The NHS has advised that despite the uncomfortable symptoms, the bug usually passes in approximately two days.

Norovirus symptoms

Here are the norovirus symptoms you should be on the lookout for and are said to develop within one to two days of being infected:

  • feeling sick (nausea)
  • diarrhoea
  • being sick
  • high temperature
  • headache
  • aching arms and legs

The NHS added within one to two days of being infected, norovirus symptoms start suddenly.

How to treat norovirus

If you or someone you know develop the above symptoms, stay off school and work until you have not been sick or had diarrhoea for at least two days as this is the most infectious period.

You should also treat norovirus at home and not visit hospitals or care homes when you have the virus.

The NHS says that the most important thing you should do is to rest and consume lots of fluids to avoid dehydration.

It also says that you will start to feel better in two to three days.

How norovirus is spread

Norovirus can be spread "very easily" in multiple ways including through close contact with someone who has it. 

Additionally, it can be spread by touching infected surfaces or objects and then touching your mouth.

You can also get norovirus by eating food that's been prepared or handled by someone with the bug.
