The German tennis player Tommy Haas has pulled out of this week's Basle Indoors tennis tournament in Switzerland after contracting swine flu.
The 31-year-old consulted his doctor after suffering flu symptoms and was diagnosed with the H1N1 strain.
Haas, this year's Wimbledon semi-finalist, also withdrew from the Stockholm Open in October because of flu.
He says he's quite relaxed because he knows that swine flu is a particularly strong form of flu but when you're in a good physical condition like him, then you can quickly beat it off.
