Symptoms of nasty winter illness that will increase for ‘the next number of weeks’

Norovirus cases continue to rise across Ireland

According to reports, the number of norovirus cases have doubled since the beginning of 2025.

Those most affected by the virus are aged over 65 with that age group making up 67% of cases.

Anyone with norovirus has been urged to stay at home until they're symptom-free.

Norovirus is an extremely contagious stomach bug that causes diarrhea, vomiting, nausea, and stomach pain.

People may also suffer from a slight fever, headaches, and painful stomach cramps.

Aching limbs are another rare symptom.

The HSE has noted an increase in cases in recent weeks and is urging anyone displaying signs of the virus to stay at home

It is believed that the virus will circulate at high levels for "the next number of weeks."

The peak season for Norovirus is between December and April, but the HSE confirmed cases are circulating at high levels in the community this month.

There is no cure for norovirus, but symptoms tend to ease after two to three days.

You can take paracetamol to ease symptoms and drink plenty of fluids.

The HSE stressed that all you can do is let the virus run its course, but staying home is essential.

Anyone with norovirus should remain at home until they're symptom-free.

Parents have been urged not to send their children to school if they're displaying signs of the virus as it can be incredibly contagious amongst their age group.
