Hemorrhagic fever
Hemorrhagic Fever
Hemorrhagic fever (pronunciation: /hɛməˈrædʒɪk ˈfiːvər/) is a term used to describe a group of illnesses that are caused by several distinct families of viruses.
Etymology
The term "hemorrhagic fever" is derived from the Greek words "haima" meaning blood and "rhegnumai" meaning to break forth; and the Latin word "febris" meaning fever. It refers to a fever that is accompanied by bleeding disorders.
Definition
Hemorrhagic fever is characterized by a high fever, damage to the lymphatic system, changes in the vascular system, and abnormal bleeding (hemorrhage). These viruses can affect multiple organs and damage the body's ability to regulate itself.
Causes
Hemorrhagic fevers are caused by viruses from four families: Arenaviridae, Filoviridae, Bunyaviridae, and Flaviviridae. Examples of these viruses include Ebola virus, Marburg virus, Lassa fever virus, and Dengue fever virus.
Symptoms
Symptoms of hemorrhagic fever include fever, fatigue, dizziness, muscle aches, loss of strength, and exhaustion. Patients with severe cases often show signs of bleeding under the skin, in internal organs, or from body orifices like the mouth, eyes, or ears.
Treatment
Treatment for hemorrhagic fever primarily involves supportive care. Ribavirin, an antiviral drug, has been effective in treating some types of hemorrhagic fevers.
Prevention
Prevention of hemorrhagic fever involves avoiding contact with host species, using insect repellent, wearing protective clothing, and practicing good hygiene and sanitation.
