The first case of swine flu in Wales has been confirmed as an unnamed 31-year-old man from Caerphilly who recently travelled to the US.
He is recovering at home with mild symptoms. Family members and friends have been offered antiviral medication, while seven more suspected cases remain under observation.
Says the Chief Medical Officer for Wales, Dr Tony Jewell: "It is likely that further cases will continue to emerge and we are continuing to monitor the situation very closely. However, while numbers remain low, our focus continues to be on learning as much as we can about the virus and working to slow its spread.
"Our advice to the public remains the same: people should follow good respiratory and hand hygiene to help prevent the spread of influenza - always using a tissue to catch sneezes, throwing away used tissues where germs can linger and regularly washing your hands, or cleaning them with a sanitising gel.
"Although it is natural for people to feel apprehensive, we would like to reassure the public that we have been working to prepare for the arrival of the virus for many years and have robust procedures in place."
