What is viral hemorrhagic fever?
viral hemorrhagic fever is a type of virus that generally causes internal bleeding. These diseases tend to be more common in a tropical environment, especially on the African continent. There are many different types of viral haemorrhagic fever and most of them are transmitted to people from animals or insects, although some can become infectious among people even under the right circumstances. Some of these diseases are very deadly for various reasons, and there are some concerns among experts that one day they could be used as weapons of biological attacks. Some of the better known diseases of viral hemorrhagic fever are Ebola and Dengue fever.
There are three basic phases of symptoms of most diseases of viral hemorrhagic fever. Initially, one does not have to think that symptoms reflect nothing more serious than the case of the flu. For example, people usually develop fever, some body pain, fatigue and nausea. Symptoms may vary somewhat between all different viruses, but are generally quite common for the first phase.
Sometimes there may be no other noticeable symptoms, but often there is a second phase where the organs or veins of the person begin to escape blood. This can manifest in many different ways, including bleeding from different body openings and all complications of serious organ failure. In the end, it is often the third phase where a person suffers damage to the nervous system, leading to seizures and other problems. Some of these diseases may eventually be deadly, while others are much surviving.
The cause of viral haemorrhagic fever is usually the process of people coming into contact with animals. In general, the most common animals that spread these diseases are rats, but some are also distributed by blood parasites such as ticks. Diseases are mostly transmitted by contact of body fluid between people and animals, but it can sometimes become air through dried stool particles. Some of these viruses can spread directly among the peopleMi, and if so, it is generally also through body fluid contact.
Most of the time, it is not in fact possible for doctors to cure a viral hemorrhagic fever. This is a general problem with most viral diseases. The body's self -defense is usually the only thing that can stop the virus, and it takes most of the time. Doctors sometimes use antiviral drugs and in some cases can be useful. There are also some vaccines that could be useful to prevent certain specific tribes.
