Federer, who has only played in 2 tournaments thus far this year (both of which he lost to 20-year-olds), announced on Saturday that he has been diagnosed with mononucleosis. His doctors report that the champ likely developed mono in December of 2007, but he has now been medically cleared to compete.
The NYTimes description of infectious mono: Mononucleosis is an infection usually caused by the Epstein-Barr virus. It can produce flulike symptoms and extreme, lingering fatigue. Physicians often discourage those with mononucleosis from taking part in intense physical activity because of the risk of rupturing the spleen, which can become enlarged because of the infection.
Federer reports that "They weren’t sure I was over it, but now I’m creating antibodies, and this really shows you are over it". He is now focusing on Beijing this summer...
