EXPLAINER: Symptoms of nasty bug 'that spreads easily' on the rise in Ireland

One of Ireland's most common bugs could be in the rise over the next few weeks with colder, winter weather approaching. 

Norovirus, or the winter vomiting bug, causes vomiting and diarrhoea. 

Despite its name, the winter vomiting bug can be caught at any time of the year. 

It is quite an unpleasant illness but generally only lasts a few days.

Symptoms include feeling or getting sick, having diarrhoea, a small fever, headaches, stomach cramps, and aching limbs, according to the HSE.

These will usually last for two or three days, during which time it is fine to look after yourself or your child at home. 

It is advised to avoid going to the GP as the virus is easily spread.

There is no cure for the illness and unless there is a risk of a more serious problem, you do not need medical advise.

It's important not to become dehydrated if you have a chronic medical condition such as diabetes.

Norovirus spreads very easily especially in public places such as hospitals, nursing homes and schools.

You can catch it if small particles of vomit or poo from an infected person get into your mouth.

This can happen through close contact with someone with norovirus, touching contaminated surfaces or objects, or eating contaminated food.

You are most infectious from when your symptoms start until 48 hours after all your symptoms have disappeared.

To avoid getting or spreading norovirus, remember to regularly wash your hands, disinfect surfaces, wash clothes and bedding, and do not share towels.
