Niki Lauda has left Vienna's AKH hospital where the Mercedes non-executive chairman was admitted before the new year after contracting the flu while on holiday in Ibiza.
When he fell ill, Lauda was still in recovery mode following the lung transplant he underwent last summer.
Given the weakness of his immune and pulmonary systems, a benign case of the flu was treated with the utmost caution by his doctors who decided to airlift the F1 legend to Austria and keep him in intensive care for the required period.
Professor Walter Klepetko, head of the thoracic department at AKH, has told Austrian news agency APA that Lauda had been released from the hospital.
The surgeon added that Lauda's flu infection did not put the three-time world champion's condition at risk and that artificial respiration had not been necessary.
The Mercedes team was hoping to welcome its chairman back in the paddock for the start of the F1 season in Melbourne, but Lauda will obviously require a green light from the faculty before traveling Down Under.
