A fourth case of swine flu has been confirmed in the Republic, the Department of Health said today.
The Department's chief medical officer Dr Tony Holohan said the latest person to test positive for the virus was a man from the south who had recently returned from New York.
Dr Holohan said the patient was aware of his condition and was being treated at his home. He also said that all necessary public health protection measures to minimise the spread of the virus had been taken.
The case was unconnected with the three previous cases of influenza type A (H1N1) confirmed in the Republic. The last two those cases also involved people returning from New York.
The Department of Health said it expected additional cases of the virus which has killed 115 people worldwide.
In order to help minimise the extent of the outbreak, people were again warned to take personal protection measures such as using and disposing of tissues and thoroughly washing hands.
The Department also urged people who have recently visited an affected area and fallen ill with flu-like symptoms to contact their GP by telephone and not turn up at a surgery or A&E unit.
The World Health Organisation confirmed today there were now 15,920 reported cases of swine flu in 57 countries.
The first case in the Republic, confirmed at the beginnning of last month, involved a young man who had recently returned from Mexico. He was treated with the antiviral drug Tamiflu and remained in quarantine at home until he recovered.
US companies have begun preliminary work on a vaccine for the new H1N1 flu and should begin clinical trials in the coming months, US health official said last week.
