DictionarySeehantavirushantavirus pulmonary syndrome
hantavirus pulmonary syndromea febrile disease caused by several species of Hantavirus (Andes, Bayou, Black Creek Canal, New York, and Sin Nombre viruses) in North and South America and characterized by thrombocytopenia, leukocytosis, and capillary leakage in the lungs, with death due to shock and cardiac complications.An often fatal respiratory tract infection with massive acute pulmonary edema often at death caused by a hantavirus; the first cluster occurred in the Four Corners region of Southwestern US Epidemiology Mean age 32, 61% women, 72% Native American Case definition Unexplained bilateral interstitial infiltrates on chest films, arterial O2 saturation < 90% Prodrome Fever, myalgia (100%), cough or shortness of breath (75%), GI symptoms, headache, tachycardia, tachypnea, hypotension Lab Leukocytosis—± 26 x 109/L—often with myeloid precursors, increased haematocrit, thrombocytopaenia of ±64 x 109/L, increased PT, increased aPTT, increased LD, decreased serum protein, proteinuria Prevention Vaccine is being developedhantavirus pulmonary syndrome An often fatal RTI caused by a hantavirus; the first cluster occurred in the Four Corners region of Southwestern US Epidemiology Mean age 32, 61% ♀, 72% Native American Case definition Unexplained bilateral interstitial infiltrates on chest film, arterial O2 saturation < 90% Prodrome Fever, myalgia-100%, cough or SOB-76%, GI Sx, headache, tachycardia, tachypnea, hypotension Lab Leukocytosis–± 26 x 109/L, often with myeloid precursors, ↑ Hct, thrombocytopenia of ±64 x 109/L, ↑ PT, ↑ aPTT, ↑ LD, ↓ serum protein, proteinuria Diagnosis Immunohistochemistry, Western blot, ELISA, IgM capture ELISA; massive acute pulmonary edema is common at deathHan·ta·vi·rus pul·mo·na·ry syn·drome (hahn'tă-vī'rŭs pul'mŏ-nar-ē sin'drōm) A febrile disease caused by several species of Hantavirus (Andes, Bayou, Black Creek Canal, New York, and Sin Nombre viruses) in North and South America and characterized by thrombocytopenia, leukocytosis, and capillary leakage in the lungs, with death due to shock and cardiac complications. hantavirus pulmonary syndrome Acute respiratory illness featuring a brief period of fever, muscle pains, headache, nausea and cough followed by severe shock and pulmonary oedema simulating the acute adult RESPIRATORY DISTRESS SYNDROME (ARDS). The mortality without specific treatment is 50–75 per cent but the drug ribavirin is effective. The disease is caused by a strain of hanta virus and was originally though to be acquired only from rodents. Human case-to-case infection has now been demonstrated.AcronymsSeeHPSThesaurusSeesyndrome |
