Norovirus infections have risen by more than a third in just two weeks, according to government figures. New data from the UK Health Security Agency (UKHSA) shows a sharp increase in the winter vomiting bug, with cases now twice what they would typically be at this time of year.
In total, 708 norovirus infections were reported in the two weeks leading up to February 12 – a 34% rise from the previous fortnight, which saw 685 cases. Prior to the Coronavirus pandemic, the two week average for norovirus at this time of year would be 373 cases.
Infections in people aged 65 and older have largely contributed to the increase, the Mirror reports . The six key symptoms of the virus are nausea, diarrhoea, vomiting, a high temperature, a headache and aching arms and legs.

Symptoms generally peak for one to two days before things start to improve. The UKHSA advises that people suffering from norovirus symptoms stay at home and keep hydrated.
It is also important that people do not return to work or send children to school until 48 hours after symptoms have cleared up to avoid passing the virus onto others. People who have had norovirus should avoid visiting elderly or poorly relatives, especially if they are in a hospital or care home.
Commenting on the current rise in cases, Doctor Lesley Larkin, surveillance lead at UKSHA, said: “Norovirus levels across England are nearly double what we expect to see at this time of year - particularly in those aged 65 and older.
“It is important that anyone with symptoms avoids visiting loved ones in a care home or hospital while unwell or until 48 hours after symptoms have cleared. This will help stop the spread of the virus to those most vulnerable.”
Washing hands frequently and thoroughly is important in stopping the spread, as alcohol hand gels do not kill norovirus. This is especially key for the very young, elderly or those with weakened immune systems, who are most at risk.
NHS medical director Professor Sir Stephen Powis said earlier this month that norovirus is a “really unpleasant illness” to catch but “for the vast majority of people” it will usually pass in a couple of days.
He added that the best way to help yourself recover and avoid putting others at risk is to self-treat at home.
