[Viral hemorrhagic fevers in Brazil].
To call attention to viral hemorrhagic fevers, diseases that are mostly underdivulged and, probably, underreported, we present here case reports of the 4 diseases of this kind that occur in Brazil: yellow fever, dengue haemorrhagic fever/dengue shock syndrome, arenavirus haemorrhagic fever and hantavirus cardiopulmonary syndrome. Relevant clinical, epidemiological and laboratorial diagnostic aspects of these viral haemorrhagic fevers are also shown here. These diseases have a high case fatality rate, induce capillary leaking and blood coagulation disturbances that are evidenced by hemoconcentration and thrombocytopenia. An early clinical diagnosis and treatment is fundamental for patient survival.
