To the Editor: Dengue infection is an endemic and epidemic urban disease (1), transmitted by infected Aedes mosquitoes. Its incidence is increasing in tropical and subtropical areas (1,2) because of 1) introduction of the virus into areas where it was not previously endemic, and 2) the spread of the 4 serotypes and the vector in disease-endemic areas (2,3). Infection with 1 serotype provides li...
Two distinct syndromes associated with dengue virus infection are prevalent in tropical Asia; dengue fever, a benign disease characterized by fever, myalgia, leucopenia and a maculo-papular rash and dengue hemorrhagic fever (DHF), accompanied by fever, shock, hemorrhagic diathesis and a significant mortality.1 The dengue viruses, a group of antigenically related members of the Group B arthropod...
Existing mouse models of lethal Ebola virus infection do not reproduce hallmark symptoms of Ebola hemorrhagic fever, neither delayed blood coagulation and disseminated intravascular coagulation nor death from shock, thus restricting pathogenesis studies to nonhuman primates. Here we show that mice from the Collaborative Cross panel of recombinant inbred mice exhibit distinct disease phenotypes ...
Rodent-borne hantaviruses (family Bunyaviridae, genus Hantavirus) cause hantavirus pulmonary syndrome in the Americas and hemorrhagic fever with renal syndrome in Europe and Asia. The viruses are transmitted to humans mainly by inhalation of virus-contaminated aerosols of rodent excreta and secreta. Classic clinical hemorrhagic fever with renal syndrome occurs in five phases: fever, hypotension...
More than 600 sera from 245 patients with a clinical diagnosis of hemorrhagic fever were preserved by the Hemorrhagic Fever Commission during the Korean Conflict, 1951-1954. These sera were tested for IgM- and IgG-specific antibodies to Hantaan virus by enzyme immunoassay and for hantaviral antigen by immunoassay; one serum from each patient was tested by plaque reduction neutralization using b...
The mechanisms contributing to bleeding complications in dengue hemorrhagic fever were studied by investigating the pattern of activation of the coagulation and fibrinolytic systems in 50 children with severe dengue hemorrhagic fever. Thirteen patients (26%) died, and activation of coagulation was most pronounced in the deceased group. Fibrinolysis was also activated, but this activation was re...
Seroprevalence of Crimean-Congo hemorrhagic fever virus (CCHFV) is high in some regions of Greece, but only 1 case of disease has been reported. We used 4 methods to test 118 serum samples that were positive for CCHFV IgG by commercial ELISA and confirmed the positive results. A nonpathogenic or low-pathogenicity strain may be circulating.
Fifteen (14%) of 105 women with Ebola hemorrhagic fever hospitalized in the isolation unit of the Kikwit General Hospital (Democratic Republic of the Congo) were pregnant. In 10 women (66%) the pregnancy ended with an abortion. In 3 of them, a curettage was performed, and all 3 received a blood transfusion from an apparently healthy person. One woman was prematurely delivered of a stillbirth. F...
From February to August 2003, 38 persons were infected with Crimean-Congo hemorrhagic fever (CCHF) virus in Mauritania; 35 of these persons were residents of Nouakchott. The first patient was a young woman who became ill shortly after butchering a goat. She transmitted the infection to 15 persons in the hospital where she was admitted and four members of her family. In Nouakchott, two disease c...
