hantavirus pulmonary syndrome

(redirected from Navajo Flu)

hantavirus pulmonary syndrome

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.
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 developed

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.

But an early front-page headline in USA Today called the illness "Navajo flu," The Arizona Republic labeled it the "Navajo epidemic," and NBC News referred to the "Navajo disease."
Tribal members later charged that coverage of the outbreak, which many national outlets labeled "Navajo flu" or the "Navajo disease," was insensitive and inaccurate.
But larger outlets, including the Chicago Tribune, Cleveland Plain Dealer, San Francisco Chronicle, Vancouver Sun, Orlando Sentinel and CBS News have referred to the illness at least once as "Navajo flu" or a "Navajo disease." A few, such as Reuters and USA Today, used such terms well after the virus had been identified.
