| catarrhal inflammation | An inflammatory process that is most frequent in the respiratory tract, but may occur in any mucous membrane, and is characterised by hyperaemia of the mucosal vessels, oedema of the interstitial tissue, enlargement of the secretory epithelial cells (which proliferate and form conspicuous globules of mucus), and an irregular layer of viscous, mucinous material on the surface; as exudation progresses, variable numbers of neutrophils migrate into the affected tissue and are included in the exudate, along with fragments of degenerated and necrotic epithelial cells; such an inflammation may frequently become mucopurulent.

| 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) |
| aestivoautumnal fever | <infectious disease> A tropical parasitic disease caused by one of the genus Plasmodium and carried by infected mosquitoes of the genus Anopheles.
