Symptoms that mean 'stay home' as 'extremely contagious' virus sweeps UK

A new strain of norovirus has hit the UK and anyone who gets it is advised to stay away from others for 48 hours

by · The Mirror

A new virulent strain of the norovirus, often referred to as the 'winter vomiting bug', is sweeping the country. The UK Health Security Agency (UKHSA) reports that the Kawasaki strain, also referred to as variation GII.17, now accounts for 70% of cases.

Dr John Burke from AXA Health warned earlier this week of the virus' "extremely contagious" nature. Amid surging cases, which have reportedly doubled since last year according to AXA Health, sufferers are being advised to hunker down at home and shun social contact for two days post-symptoms. This 'Kawasaki bug', first detected in the city of Kawasaki, Japan, back in 2014, has rapidly established itself as the predominant strain.

Gauri Godbole, deputy director of gastrointestinal infections at the UKHSA, said: “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, who is chief medical officer at AXA Health and has been a GP for more than a quarter of a century, said: “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.”

NHS symptoms of norovirus

The NHS says that norovirus, also called the "winter vomiting bug", is a stomach bug that causes vomiting and diarrhoea. It can be very unpleasant, but usually goes away 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 symptoms start suddenly within a day or two of being infected.

How to treat norovirus

You can usually treat yourself or your child at home. The most important thing is to rest and have lots of fluids to avoid dehydration.

You will usually start to feel better in two or three days, the NHS says. Find out how to treat diarrhoea and vomiting in children and adults.

The NHS adds: "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."

How norovirus is spread

The NHS says norovirus can spread very easily. You can catch norovirus from:

  • close contact with someone with norovirus
  • touching surfaces or objects that have the virus on them, then touching your mouth
  • eating food that's been prepared or handled by someone with norovirus

Washing your hands frequently with soap and water is the best way to stop it spreading. Alcohol hand gels do not kill norovirus.
