With new lifestyles and advent of new things, many new diseases have also evolved. We have been hearing about viral fever for a lot of time, but now there is a viral hemorrhagic fever. This is normally known as VHF. It is a group of febrile illness caused from several viral families of RNA group. This dangerous and highly infectious virus ends up with a syndrome accompanied by fever, vomiting, mucosal, malaise and hypotension.
Arenaviridae, Bunyaviridae, Filoviridae, and Flaviviridae are the four types of viruses from the VHF disease family. They are mainly responsible for Viral Hemorrhagic Fever
* Arenaviridae
This spreads to humans through contact of rodent and has a virus named Lassa, which is found in Africa. Arenaviridae leads to high mortality in West Africa. This kind of fever was first researched and found to be in Nigeria in a place named Lassa, in the year 1969. The small rodent from the reservoir is the source of transmission.
* Bunyaviridae
They are a part of RVF virus and is a kind of arthropod virus. This kind of virus is transmitted to humans through mosquitoes who normally sit on dead species especially dead animals or infected ones. CCHF virus is normally found in ticks which causes a form of VHF and has aerosol transmission in them. This occurs in Asia, Africa and Europe.
* Filoviridae
Including Ebola and Marburg viruses, this is the most affecting virus belonging to filoviridae, which was in conversation in 1976 after outbreaks of febrile. Ebola can also be defined further as
* Ebola- Zaire
* Ebola- Sudan
* Ebola- Ivory Coast
* Ebola- Reston
It got these names as this virus affects these areas and is life threatening.
* Flaviviridae
This virus causes yellow fever and dengue fever. Both of which are mosquito-borne. Yellow fever is usually found in tropical Africa and South America, and dengue fever is found in Asia, Africa, and America. They too are hazardous to life and their continuous presence can cause epidemic diseases.
The above explanation of the virus shows the hazardous qualities they possess.
