NHS shares norovirus symptoms that mean 'stay at home' as 'extremely contagious' virus sweeps UK

A new potent strain of norovirus, commonly known as the 'winter vomiting bug', is making its way across the UK. The UK Health Security Agency (UKHSA) has reported that the Kawasaki strain, or GII.

17 variation, is now responsible for 70% of cases. Dr John Burke from AXA Health earlier this week highlighted the virus's "extremely contagious" nature.

With cases reportedly doubling since last year, according to AXA Health, those affected are being urged to stay at home and avoid social contact for two days after symptoms cease. The 'Kawasaki bug', which was first identified in Kawasaki, Japan, in 2014, has quickly become the dominant strain.

Gauri Godbole, deputy director of gastrointestinal infections at the UKHSA, advised: "If you have diarrhoea and vomiting, do not return to work, school or nursery until 48 hours after your symptoms have stopped and don't prepare food for others in that time either. If you are unwell, avoid visiting people in hospitals and care homes to prevent passing on the infection in these settings."

Dr Burke, chief medical officer at AXA Health with over 25 years as a GP, noted: "Norovirus is an extremely contagious virus that spreads through contact and can cause sickness and diarrhoea for those infected. Often referred to as the 'winter vomiting bug' cases of Norovirus soar over autumn and winter as more people spend time indoors, in close proximity to each other.", reports the Mirror.

The NHS has outlined the symptoms of norovirus, also known as the "winter vomiting bug", which is a stomach bug causing vomiting and diarrhoea. While it can be extremely unpleasant, it typically clears up in about two days.

The main symptoms of norovirus are:

• feeling sick (nausea)
• diarrhoea
• being sick (vomiting)

You may also have:

• a high temperature
• a headache
• aching arms and legs

The primary symptoms of norovirus are sudden and usually appear within one to two days of infection. According to the NHS, you or your child can generally self-treat at home. The key is to rest and stay hydrated to prevent dehydration.

Improvement is usually seen within two to three days. Guidelines on how to manage diarrhoea and vomiting in children and adults are available.

The NHS further advises: "Stay off school or work until you have not been sick or had diarrhoea for at least two days. This is when you're most infectious. Do not visit hospitals or care homes during this time."

Norovirus spreads easily, warns the NHS. It can be contracted from various sources.

Regular hand washing with soap and water is the best defence against its spread, as alcohol hand gels do not kill the virus.

If certain conditions apply, seek advice from 111 immediately. They will guide you on the next steps and can arrange a call from a medical professional if necessary.

In case of severe symptoms, call 999 or go to A&E. The NHS recommends not driving to A&E - instead, have someone else drive you or call 999 for an ambulance.

Remember to bring any medications you are currently taking.
