Norovirus cases are sweeping through patients and NHS staff in Swindon and Wiltshire, with cases doubling nationally from this time last year.

Local NHS services warned there has been an increase in the number of cases in hospitals and care homes across the region, putting pressure on an already strained local health service.

Connie Timmins, the lead nurse for infection at the region’s Integrated Care Board, urged patients to prevent the spread of the bug by staying at home.

She said: “The best way to stop the spread of norovirus is to stay at home and away from others until at least 48 hours after symptoms have passed.

“Even if a person is no longer being sick or running to the loo, the virus may still be present in their system, which means it can still be passed on.

“Staying at home, as well as avoiding health and care settings, including hospitals, GP practices, pharmacies and care homes, will protect others, especially those who are vulnerable, from falling ill.”

Norovirus is highly infectious and causes sickness, diarrhoea and dehydration.

People with the bug should rest, drink plenty of fluids and use NHS 111 online to seek help if they are suffering prolonged or worsening symptoms.

Washing hands regularly with soap can kill norovirus germs, as can disinfecting toilets and surfaces.
