Psittacosis centenary -- 'pneumotyphus' reviewed.

Since 1979, when psittacosis, human infection with Chlamydia psittaci, became a notifiable disease in South Africa, only 4 cases have been reported to the State health authorities. While this is not a common illness and some cases may not be reported, there is a strong possibility that this infection is being overlooked because of lack of awareness of its wide range of manifestations. A characteristic case is described and the complications and management of psittacosis are reviewed with particular reference to South Africa.
