| parrot fever | <chest medicine, disease> Psittacosis is primarily an infectious disease of birds caused by the bacterium Chlamydia psittaci. Transmission from infected birds results in a relatively rare febrile illness characterised by pneumonia and systemic symptoms. A flu-like illness can also occur. Almost any bird can harbor this bacterium in their excreta, tissues, feathers and secretions, but parrots, parakeets and budgerigars are the most common. Psittacosis is considered an occupational disease of pet shop owners. Psittacosis is almost always transmitted to humans by the respiratory route. Average incubation is 7-14 days. (27 Sep 1997) |

| aden fever | <virology> A tropical disease caused by dengue virus (Arbovirus), that is transmitted by the bite of an infected mosquito of the genus Aedes). Four severity grades of the illness are seen: Grade I: fever and constitutional symptoms. Grade II: grade I plus spontaneous bleeding of skin, gums or gastrointestinal tract. Grade III: grade II plus agitation and circulatory failure. Grade IV: profound shock. Grade I infection is seen most frequently in world travelers, where it is usually self-limited and rarely fatal. The other grades are referred to as dengue haemorrhagic fever and are often fatal. Dengue haemorrhagic fever appears to be an infection by one of the other dengue viruses. Prior immunity to a different dengue virus type appears to be important in the development of the more serious haemorrhagic form. Vaccines are available. Protection from mosquitoes is an important preventive measure. (15 Jan 1998) |
