The former South African president was admitted to the Milpark Hospital in Johannesburg earlier this week (begs24Jan11), and he was diagnosed with an acute respiratory infection.
The 92 year old is said to have responded "very well" to treatment, and will now be monitored carefully while recovering at home.
Surgeon General Vijay Ramlakan explains, "We wish to confirm that Dr. Mandela was admitted to hospital earlier this week and underwent a few specialised investigations... These tests have been carried out at various facilities over the years and are a normal part of his medical regiment. Such tests are considered routine for a patient of his profile.
"At present Dr. Mandela is in high spirits and has been visited by his family and friends. Medically, at present, there is no need to panic. Dr. Mandela suffers from diseases common to people of his age as well as conditions that have developed over the years for which he receives chronic medication.
"He recently developed an acute respiratory infection, for which he received treatment and has responded very well. He is stable but will be monitored closely. Despite all of this, his amazing, positive attitude allows him to cope with the difficulties of old age with the greatest of graces."
