They are therefore urging those who catch the virus not to go back to work or school until at least 48 hours after symptoms pass, to avoid passing it on to others.
The NHS is responding by launching a new social media campaign to help people avoid catching the bug if possible, and recognise and deal with the symptoms of norovirus at home if they are unlucky enough to get infected.
Health bosses are also encouraging those who need it to seek help from the free, 24/7 NHS 111 phone and online service rather than going to hospital or their GP, where they risk infecting others.
Norovirus is one of the most common stomach bugs in the UK
We’ve already seen a number of hospitals and schools affected by norovirus, and unfortunately instances like these are likely to rise over the coming weeks. It’s a really unpleasant illness to catch, but for the vast majority of people it will usually pass in a couple of days, and self-treating at home is the best way to help yourself and avoid putting others at risk. Crucially, if you’re experiencing norovirus symptoms it’s important that you don’t return to work or school for 48 hours after they clear – and avoid visiting elderly or ill friends and relatives - to avoid spreading it to other people.
It’s called the winter vomiting bug because it’s more common in winter, although it can be caught at any time of the year. It is highly contagious, and is easily passed on at home, at hospital, or in the local community, and those who have been infected remain carriers for some time.
It is therefore important that those who have experienced symptoms, or have been in contact with friends or family who have recently had norovirus, limit their contact with young children, elderly friends and relatives or those with pre-existing medical conditions.
Those who are experiencing severe symptoms or are worried about their children can seek guidance on what to do on the NHS.uk website, or by using the free NHS 111 phone or online service.
Five ways to limit the spread of norovirus
- Stay at home if you are experiencing norovirus symptoms. Do not return to work or send children to school until 48 hours after symptoms have cleared. Also avoid visiting elderly or poorly relatives, particularly if they are in hospital.
- Wash your hands frequently and thoroughly with soap and warm water. Alcohol hand gels don’t kill norovirus.
- Use a bleach-based household cleaner or a combination of bleach and hot water to disinfect household surfaces and commonly used objects such as toilets, taps, telephones, door handles and kitchen surfaces.
- If you are ill, avoid cooking and helping prepare meals for others.
- Wash any contaminated clothing or bedding using detergent and at 60°C, and if possible wear disposable gloves to handle contaminated items.
