"Tragic though this is for the family and friends, we are not seeing an increase in rates of cases, compared to normal seasonal flu, where we see a number of serious cases and deaths each year."
The chief medical officer for Wales, Dr Tony Jewell said there had been more than 50 swine flu-related deaths in the UK since the flu pandemic arose in April.
"I understand that the first death of someone with swine flu in Wales will naturally worry people and cause concern, however I would assure people that for the vast majority of healthy people, the infection remains mild and people recover within five to seven days with rest, plenty of fluids and symptomatic treatments," he added.
"People with underlying health conditions, especially heart and lung diseases, are at most risk.
"Even in the at risk groups - those with chronic conditions, pregnant women and children under five - most people get over the infection with no major concerns.
"If people are concerned, or if they are in these at risk groups, they should contact their GP or NHS Direct Wales.
"Antivirals have the most impact within 48 hours of the onset of flu-like symptoms."
