Norovirus, also known as the 鈥榳inter vomiting bug鈥�, is the most common stomach bug in the UK. It can spread easily through close contact, or by contaminated surfaces, food or water.
Symptoms
The main symptoms of norovirus include a sudden onset of nausea, followed by projectile vomiting and diarrhoea, usually 1 to 2 days after becoming infected. Other common symptoms include a high fever, a headache and aching arms and legs.
Prevention
Good hand hygiene is important to stop norovirus spreading.
To stop norovirus spreading, you should:
- wash your hands thoroughly using soap and warm water after using the toilet or contact with a sick individual and before preparing and eating food
- stay off school or work until you have not been sick or had diarrhoea for at least 2 days
- not rely on alcohol gels instead of washing your hands, as these do not kill the virus
- wash any contaminated clothing or bedding using detergent at 60掳C using disposable gloves to handle any items
- use bleach-based cleaners to disinfect surfaces
If you catch norovirus, stay home for 48 hours after your symptoms clear.
Recovery
Most people will make a full recovery in 2 to 3 days without needing any medicine. It is important to keep hydrated 鈥� especially children and the elderly.
Try not to visit A&E (accident and emergency) or GP surgeries if you have symptoms of norovirus unless advised to do so by a healthcare professional, as this may spread the bug to others. Call ahead to a GP or ring NHS 111 if you are worried about your symptoms.
