F1 legend Schumacher hit by lung infection
The effects on the fragile state of health of the 45-year-old were unknown, the German newspaper 'Bild' reported yesterday.
Schumacher's spokeswoman Sabine Kehm told the newspaper: "We are not commenting on speculation."
Schumacher has been in a coma since his December 29 ski accident in the French Alps resort of Meribel when he badly injured his head, causing serious swelling of the brain.
The doctors treating him in the hospital in the French city of Grenoble two weeks ago said they were trying to coax him out of the coma by reducing his sedation.
With little information being given to media, the hospital has been left to fend off rumours. Last Thursday, it had to deny speculation flaring on social networks that Schumacher had died.
It has been reported that Schumacher's wife Corinna spends hours talking to her husband at his bedside to try to help him round from his coma.
She has spoken to the seven-time world champion – who is being kept under anaesthetic at the University Hospital in France – every day without any response. (© Daily Telegraph, London)
