Vomiting Bug

A vomiting bug can be really unpleasant, but it’s usually over within two or three days. There’s no cure, you have to let it run its course.


  • Suddenly feeling sick
  • Projectile vomiting
  • Watery diarrhoea
  • You might also have a slight fever, headache, painful stomach cramps and aching limbs.

The best thing to do is to stay at home until you’re feeling better, so that you don’t pass it on to others.

It’s important to drink plenty of fluids to prevent dehydration, you can try oral rehydration fluids which you can buy from pharmacies and some supermarkets.

Take paracetamol for any fever or aches and pains, get plenty of rest and, if you feel like eating, eat plain foods such as soup, rice, pasta and bread.

Stop the virus spreading. Vomiting bugs can spread very easily, so you should wash your hands often while you’re ill and stay off work until at least two days after the symptoms have cleared, to reduce the risk of passing it on.

Clean toilet seats, flush handles, taps, surfaces and door handles every day.

Seek medical advice if:

  • You have symptoms of dehydration: dry mouth, only passing small amounts of urine, which is dark in colour, or no urine at all, feeling dizzy, reduced consciousness.  Young children and the elderly are especially at risk.
  • You have bloody diarrhoea
  • Your symptoms haven’t started to improve after a few days
  • You have a serious underlying health condition, such as kidney disease, and have diarrhoea and vomiting
  • You have a weakened immune system
