We reviewed retrospectively 135 cases of serologicallyconfirmed psittacosis that were admitted to Fairfield Hospital between January 1, 1972 and March 31, 1986. The average age of the patients was 46 years. The majority (85%) of patients described a history of recent exposure to birds. The clinical features, investigations, treatment and subsequent response were analysed in 129 patients. Psittacosis was a well‐defined illness that was characterized by an abrupt onset of fever, rigors, sweats, and prominent headache, and a mild dry cough which appeared late frequently. However, respiratory symptoms were absent in 18% of patients. Diarrhoea and sore throat were occasional complaints. Over 90% of cases had an abnormal chest x‐ray film, or abnormal chest signs, or a combination of both, Most patients had a normal leukocyte count. Tetracycline drugs were used for treatment in 87% of the patients. Defervescence occurred in 92% of patients after 48 h of tetracycline treatment. There were no recrudescences of psittacosis and no fatalities. The clinical diagnosis of psittacosis can be made early usually, particularly in the presence of pneumonitis on a chest x‐ray film and a positive history of bird contact. Treatment with doxycycline (100 mg twice a day for 14 days) is recommended.
