With the number of flu victims on the rise this winter, the HSE is urging people to take care not to catch the virus, and if you do, not to pass it on!
The number of people consulting their GP about the flu has doubled over the Christmas season, with the over 65s, children under 2 and pregnant women being among the most vulnerable.

400 struck down by cruise ship cold
Meanwhile more than 400 passengers and crew on two cruise liners in the Caribbean have come down with the Winter Vomiting Bug.
Both ships, the Queen Mary 2 and the Emerald Princess, reported the illness to the US Centre for Disease Control - which says the sickness is most likely cause by the Norovirus.
Passengers on board the Queen Mary 2 say they were told to avoid the buffet because of the outbreak - and that sick passengers were told to stay in their rooms.
Similar outbreaks affected the Azura and Oriana ocean liners earlier this month.
