Symptoms of one virus to watch, amid spike of people in Ireland getting very sick

NOROVIRUS, one of the most common causes of gastroenteritis, is one to look out for this winter as it is currently increasing in Ireland.

In November, HPSC data showed norovirus diagnoses in Ireland tripled to more than 30 per week. There has also been a significant upsurge in norovirus outbreaks in healthcare facilities, it has been reported.

Norovirus is a contagious stomach bug and if two or more people in the same building or group develop vomiting within a day or so of one another, it is likely that this may be norovirus, according to the HSE.

The strain of norovirus currently circulating is that of GII.4 (Sydney) or very similar variants. This has been the dominant strain since 2012.

It's not always possible to avoid getting norovirus, but following the advice below can help stop the virus spreading:

* Stay off work or school until at least 48 hours after the symptoms have passed. You should also avoid visiting anyone in hospital during this time.
* Wash your hands frequently and thoroughly with soap and water. Do not rely on alcohol hand gels, as they do not kill the virus.
* Disinfect any surfaces or objects that could be contaminated. It's best to use a bleach-based household cleaner.
* Wash any items of clothing or bedding that could have become contaminated separately on a hot wash to ensure the virus is killed.
* Don't share towels and flannels.
* Flush away any infected poo or vomit in the toilet and clean the surrounding area.
* Avoid eating raw, unwashed produce.
