People are being reminded to protect themselves from the cold and flu virus this Christmas.

The Irish Pharmacy Union (IPU) are advising high-risk groups to be prepared and to get the flu vaccine.

The IPU say staying hydrated, as well as getting enough sleep, are some of the best ways to stay free of infection.

Other simple measures such as washing your hands and controlling stress levels are good help to protect yourself.

Bernard Duggan, of the IPU, says people with certain underlying medical conditions should take particular care at this time of the year.

He says you should also limit your contact with people who are currently suffering with a cold or flu.
