This research investigates how different RNA viruses cause hemorrhagic fevers and the underlying mechanisms of disease severity.
Analyzed various enveloped RNA viruses including filoviruses, flaviviruses, arenaviruses, and bunyaviruses.
Examined natural cycles involving hosts such as primates, bats, and rodents, and their interaction with humans and other vectors.
Evaluated the pathogenic mechanisms contributing to vascular instability and hemorrhage.
Certain viruses like Ebola and Marburg have extremely high fatality rates, while yellow fever and dengue often result in asymptomatic infections.
Pathogenic mechanisms include cytokine storm and increased vascular permeability, leading to varying degrees of hemorrhage.
Severe plasma leakage coincides with viral clearance in dengue hemorrhagic fever.
