Complications in the form of endocarditis, hepatitis, myocarditis, arthritis, keratoconjunctivitis, and neurologic complications (encephalitis) may occasionally occur. Severe pneumonia requiring intensive-care support may also occur. Fatal cases have been reported (less than 1% of cases).

 ==Overview==
-It presents chiefly as an atypical pneumonia. In the first week of psittacosis the symtoms mimic [[typhoid fever]]: prostrating high [[fever]]s, [[arthralgia]]s, [[diarrhea]], [[conjunctivitis]], [[epistaxis]] and [[leukopenia]].   [[Headache]] can be so severe that suggests [[meningitis]] and some nuchal rigidity is not unusual. Towards the end of first week stupor or even [[coma]]can result in severe cases.
-The second week is more akin of acute bacteraemic pneumococcal pneumonia with continuous high fevers, cough and dyspnoea.
 ==Complications==
 Complications in the form of [[endocarditis]], [[hepatitis]],  [[myocarditis]], [[arthritis]], [[keratoconjunctivitis]], and neurologic complications ([[encephalitis]]) may occasionally occur. Severe pneumonia requiring intensive-care support may also occur. Fatal cases have been reported (less than 1% of cases).
