1/10. Second human case of Cache Valley virus disease.We document the second known case of Cache Valley virus disease in a human. Cache Valley virus disease is rarely diagnosed in north america, in part because laboratories rarely test for it. Its true incidence, effect on public health, and full clinical spectrum remain to be determined.- - - - - - - - - - ranking = 1keywords = virus disease, virus (Clic here for more details about this article) |
2/10. Isolation of a newly recognized Bunyamwera serogroup virus from a febrile human in panama.A virus, strain 86MSP18, was isolated from the acute phase serum of a U.S. soldier with a febrile illness. He was stationed at Fort Sherman in the Republic of panama when the onset of his illness occurred. A rise in neutralizing antibody to the viral isolate was observed between the patient's acute and convalescent-phase serum samples. Virus strain 86MSP18 has been shown by plaque reduction neutralization to be closely related to but distinct from Cache Valley virus and known subtypes. It appears to be a newly recognized subtype of Cache Valley virus and is believed to be the second isolation of a Cache Valley virus subtype from a human with a febrile illness. The name "Fort Sherman" virus for strain 86MSP18 is proposed.- - - - - - - - - - ranking = 0.00025484394532801keywords = virus (Clic here for more details about this article) |

4/10. hantavirus pulmonary syndrome complicating pregnancy.OBJECTIVE: The purpose of this report is to bring to the attention of obstetric care providers the occurrence in pregnancy of a threatening pulmonary syndrome caused by hantavirus infection. STUDY DESIGN: Two recent cases of hantavirus pneumonitis in pregnancy, one complicated by adult respiratory distress syndrome, are presented. The clinical characteristics and epidemiology of the illness, which has now been reported in 12 western states, are detailed. RESULTS: hantavirus pulmonary syndrome is characterized by pneumonitis, often progressing to adult respiratory distress syndrome, which is accompanied by thrombocytopenia, lactacidemia, and leukocytosis with a marked left shift. Severe hypoxemia and lactacidemia were associated with a poor perinatal outcome. CONCLUSION: The hantavirus pulmonary syndrome occurring during pregnancy may be life-threatening and may result in fetal hypoxemic damage.- - - - - - - - - - ranking = 0.00022652795140268keywords = virus (Clic here for more details about this article) |
5/10. hantavirus pulmonary syndrome: recognition and emergency department management.Hantavirus infection with respiratory involvement is a new clinical entity. The respiratory and cardiovascular abnormalities associated with hantavirus infection define the hantavirus pulmonary syndrome (HPS). We present two cases of HPS and discuss the presentation, epidemiology, emergency department management, and differential diagnosis. Treatment of HPS involves intensive care monitoring, airway management, and cardiovascular support. Because human hantavirus infection with respiratory involvement has been recognized recently in all geographic regions of the United States, it is important for emergency physicians to recognize this syndrome's characteristic symptoms and laboratory abnormalities. The fulminant clinical course of HPS and its 65% mortality rate underscore the importance of early recognition if potentially life-saving interventions are to be initiated.- - - - - - - - - - ranking = 0.00022652795140268keywords = virus (Clic here for more details about this article) |
6/10. Recognition of Hantavirus infection in the rural setting: report of first colorado resident to survive.Since May 1993, there has been an outbreak of an acute illness with nonspecific symptoms and signs that rapidly progresses to death. The majority of the cases identified have occurred in the rural southwestern united states, predominantly in the four-corners area comprising new mexico, arizona, utah, and colorado. Findings of preliminary investigation by the Centers for disease Control and Prevention suggest that the etiologic agent is a previously unidentified strain of Hantavirus. In reported cases, infection with this virus has a very high mortality. The authors describe the primary care of the first colorado resident of the four Coloradans infected to survive documented Hantavirus-associated disease. There are potential implications for rural healthcare delivery as rapid recognition and early intervention with supportive care could improve survival.- - - - - - - - - - ranking = 0.00019821195747734keywords = virus (Clic here for more details about this article) |
7/10. hantavirus pulmonary syndrome: a clinical description of 17 patients with a newly recognized disease. The Hantavirus Study Group.BACKGROUND. In May 1993 an outbreak of severe respiratory illness occurred in the southwestern united states. A previously unknown hantavirus was identified as the cause. In asia hantaviruses are associated with hemorrhagic fever and renal disease. They have not been known as a cause of human disease in north america. methods. We analyzed clinical, laboratory, and autopsy data on the first 17 persons with confirmed infection from this newly recognized strain of hantavirus. RESULTS. The mean age of the patients was 32.2 years (range, 13 to 64); 61 percent were women, 72 percent were Native American, 22 percent white, and 6 percent Hispanic. The most common prodromal symptoms were fever and myalgia (100 percent), cough or dyspnea (76 percent), gastrointestinal symptoms (76 percent), and headache (71 percent). The most common physical findings were tachypnea (100 percent), tachycardia (94 percent), and hypotension (50 percent). The laboratory findings included leukocytosis (median peak cell count, 26,000 per cubic millimeter), often with myeloid precursors, an increased hematocrit, thrombocytopenia (median lowest platelet count, 64,000 per cubic millimeter), prolonged prothrombin and partial-thromboplastin times, an elevated serum lactate dehydrogenase concentration, decreased serum protein concentrations, and proteinuria. Rapidly progressive acute pulmonary edema developed in 15 of the 17 patients (88 percent), and 13 patients, all of whom had profound hypotension, died (case fatality rate, 76 percent). Increases in the hematocrit and partial-thromboplastin time were predictive of death. CONCLUSIONS. infection with a newly described hantavirus causes the hantavirus pulmonary syndrome, which is characterized by a brief prodromal illness followed by rapidly progressive, noncardiogenic pulmonary edema.- - - - - - - - - - ranking = 0.00044378264169829keywords = fever, virus (Clic here for more details about this article) |
8/10. puumala virus infection without signs of renal involvement.Five cases of puumala virus infection without renal involvement are described. The main signs were fever, headache, chills and thirst. Pulmonary involvement was also common. Neither increased levels of serum creatinine nor abnormal urinalyses were detected. We suggest that Hantavirus infection is included in the differential diagnosis of any febrile condition when exposure to aerosols from infectious secretions or secretions from rodents is suspected.- - - - - - - - - - ranking = 0.00020773332388648keywords = fever, virus (Clic here for more details about this article) |
9/10. hantavirus pulmonary syndrome (HPS): report of first case in louisiana.Since May 1993, 26 people have died of a "unique, previously unknown" viral illness that presents with flu-like symptoms and progresses rapidly to respiratory failure and death. Originally isolated in the four-corners region of the Southwest, the hantavirus responsible has now been isolated from patients in several other areas. In this article, we describe our experience with "the most puzzling case so far," an infection by a "cousin" of the Southwest hantaviral strain in a louisiana bridgeworker. This case is unique not only because of the slightly different makeup of the virus, but also because of the absence of deer mice, the suspected carrier of the hantavirus, in the louisiana region.- - - - - - - - - - ranking = 0.00019821195747734keywords = virus (Clic here for more details about this article) |
