Viral Hemorrhagic Fever (VHF) sounds like one of those things you just never want to get. Unlike the other pandemics and sicknesses that we have covered and plan on covering in this series, VHF is not one single sickness but a collection of different diseases that are all classified as viral hemorrhagic fevers Dengue is caused by a flavivirus that is transmitted by Aedes aegypti and occurs in two forms of classic dengue fever and hemorrhagic dengue fever. Accordingly, dengue is only one disease out of the many other diseases caused by viruses.

Clinically, this group of diseases has in common fever, fatigue, dizziness, muscle aches, and other associated symptoms that can progress to vascular leakage, bleeding and multi-organ failure Four families of enveloped RNA viruses, filoviruses, flaviviruses, arenaviruses, and bunyaviruses, cause hemorrhagic fevers.

Some viral hemorrhagic fevers (yellow fever, Crimea-Congo, etc.) can be prevented with the help of a specific preventive vaccination of medical personnel. When in contact with the patient at a distance of less than 1 meter, medical personnel work in special clothing with glasses and gloves, and also uses air respirators when the patient has. Some viral hemorrhagic fevers are spread from person-to-person through close contact with body fluids, such as blood or urine. What are the symptoms of VHF? Specific symptoms vary by type of viral hemorrhagic fever, but initial symptoms often include: fever, fatigue, dizziness, muscle aches, loss of strength and exhaustion
