What Causes Dengue Hemorrhagic Fever?

Dengue Hemorrhagic fever is potentially fatal disease. The Aedes mosquito carries the virus that spreads this disease. The National Institute of Health (NIH) of USA states that 100 million cases of dengue fever are reported each year and out of this, only a few are that of dengue hemorrhagic fever. It is caused by four types of dengue viruses. Generally, when a person infected with one of the virus catches another one, it results in hemorrhagic fever.

The antibodies developed during earlier dengue virus lead to worsening of the patient’s condition if another virus infects him. The NIH also states that apart from such patients, children lesser than 12 years old, females and Caucasians are at an increased risk of developing this disease. Those who travel to tropical areas of the world or the residents of these areas are at a greater risk of this disease.

The dengue hemorrhagic fever may turn even worse and leave the patient’s body in a shock-like condition. It is known as the dengue shock syndrome. The major symptoms of this condition are clamminess due to lot of sweating followed by cooling. The circulatory system of an infected person is badly affected and it can turn fatal. Anyone who shows these symptoms should be given emergency treatment immediately. It may include blood transfusion, intravenous fluids, oxygen therapy or platelet infusion.

Given the serious complications of the disease, it is advisable to take extra precautions when visiting or living in dengue endemic regions of the world.
