| west nile 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. (27 Sep 1997) |
| west nile virus | A species of flavivirus, one of the japanese encephalitis virus group (encephalitis viruses, japanese), which produces encephalitis experimentally when inoculated into some rodents, chicks, birds, or monkeys. In humans, it is seen most frequently in africa, asia, and europe presenting as a silent infection or undifferentiated fever (west nile fever). It is transmitted by culex spp mosquitoes.

| West's syndrome | <syndrome> An encephalopathy in infancy characterised by infantile spasms, arrest of psychomotor development, and hypsarrhythmia. (05 Mar 2000) |
| Cruz trypanosomiasis | Trypanosomiasis caused by Trypanosoma (or Schizotrypanum) cruzi and transmitted by certain species of reduviid (triatomine) bugs. In its acute form, it is seen most frequently in young children, with swelling of the skin at the site of entry, most often the face, and regional lymph node enlargement; in its chronic form it can assume several aspects, commonly cardiomyopathy, but megacolon and megaesophagus also occur; natural reservoirs include dogs, armadillos, rodents, and other domestic, domiciliated, and wild mammals. Synonym: Chagas' disease, Chagas-Cruz disease, Cruz trypanosomiasis. (05 Mar 2000) |
| South American trypanosomiasis | Trypanosomiasis caused by Trypanosoma (or Schizotrypanum) cruzi and transmitted by certain species of reduviid (triatomine) bugs. In its acute form, it is seen most frequently in young children, with swelling of the skin at the site of entry, most often the face, and regional lymph node enlargement; in its chronic form it can assume several aspects, commonly cardiomyopathy, but megacolon and megaesophagus also occur; natural reservoirs include dogs, armadillos, rodents, and other domestic, domiciliated, and wild mammals. Synonym: Chagas' disease, Chagas-Cruz disease, Cruz trypanosomiasis. (05 Mar 2000) |
| trypanosomiasis | <disease, microbiology> A parasitic disease caused by the American strain, Trypanosoma cruzi. Chagas disease is usually transmitted by the bite of the kissing bug, but may also follow breast feeding (to infants) and blood transfusion. Although much more common in South America, it does, on rare occasions, occur in the U.S. A nodular swelling (chagoma) appears at the site of inoculation following a bite. The acute phase of the disease can last 2 to 3 months and patients present with fever, headache, anorexia, conjunctivitis and myocarditis. Infants can develop meningitis and heart involvement. Trypanosomiasis can cause congestive heart failure and ventricular aneurysms. Treatment is with nifurtimox. (27 Sep 1997) |

| acute African sleeping sickness | A disease of humans caused by Trypanosoma brucei rhodesiense in eastern Africa from Ethiopia and Uganda south to Zimbabwe; it is clinically similar to Gambian trypanosomiasis but of shorter duration and more acute in form; patients suffer repeated episodes of pyrexia, become anaemic, and die commonly from cardiac failure. Synonym: acute African sleeping sickness, acute trypanosomiasis, East African sleeping sickness, East African trypanosomiasis. (05 Mar 2000) |
