Hemorrhagic Fever is a severe and potentially life-threatening illness characterized by fever, bleeding disorders, and organ failure. Numerous viruses are associated with Hemorrhagic Fever, belonging to various families such as Filoviridae, Arenaviridae, Bunyaviridae, and Flaviviridae. Notable examples include Ebola virus, Marburg virus, Lassa virus, Crimean-Congo Hemorrhagic Fever virus, and Dengue virus. Ebola virus and Marburg virus, members of the Filoviridae family, are notorious for causing Ebola Hemorrhagic Fever and Marburg Hemorrhagic Fever, respectively. These viruses are transmitted to humans through contact with infected animals or individuals, leading to severe disease characterized by internal and external bleeding. Lassa virus, belonging to the Arenaviridae family, causes Lassa fever, primarily in West Africa. Lassa fever ranges from mild illness to severe hemorrhagic manifestations. The virus is transmitted to humans through contact with rodent excreta or consumption of contaminated food. Crimean-Congo Hemorrhagic Fever virus, a member of the Bunyaviridae family, is transmitted through tick bites or contact with infected animals. It causes severe outbreaks with symptoms ranging from fever to hemorrhagic manifestations and multi-organ failure. Dengue virus, a Flavivirus, is transmitted by Aedes mosquitoes and is responsible for Dengue Hemorrhagic Fever. Severe cases can lead to plasma leakage, hemorrhage, and organ impairment. Preventing Hemorrhagic Fever involves vector control, avoiding contact with infected animals, and implementing strict infection control measures in healthcare settings. Vaccines are available for some viruses causing Hemorrhagic Fever, emphasizing the importance of global preparedness and vaccination programs.
