By surekha

Hemorrhagic fever is a kind of viral infection caused by group of viruses. Viral hemorrhagic fever can affect the function of many vital organs and the worst thing is they can damage the blood vessels affecting the transportation of oxygenated blood. Symptoms of hemorrhagic fever may range from mild to severe and in rare cases they can cause death. This disease can affect the clotting ability of blood causing bleeding. Often these viruses live in animals and get transmitted to humans when they consume or handle infected animals. It can also spread from infected individuals to others through saliva, urine and other fluids. Ebola, Marburg, Lassa and Dengue viruses cause hemorrhagic fever. People living in tropical regions are at increased risk of this fever. There is no cure for this disease.

Generally the virus is restricted to specific areas but it can spread to people who travel frequently to affected areas.

Mode Of Transmission :

An individual who touches the feces of infected animal or comes in contact with the saliva would get infected. Insects like mosquitoes, ticks, flies and animals like rodents and bats are carriers of viruses. In some cases infected person can also pass on the infection to others through saliva and exchange of body fluids. An outbreak of hemorrhagic fever occurs irregularly and cannot be predicted.
