Dengue hemorrhagic fever is a serious form of dengue fever. It is important to note that dengue fever is a prevalent mosquito-borne ailment in tropical and sub-tropical countries.

The indications of dengue hemorrhagic fever include abdominal pain, bleeding beneath the skin and frequent episodes of vomiting. The severe symptoms often arise after the individual starts to recover from the dengue virus.

What are the causes?

Dengue hemorrhagic fever can arise if an individual was bitten by a mosquito or exposed to blood infected by the virus.

There are 4 types of dengue virus and when one is bitten, he/she develops immunity to that specific virus for life. Nevertheless, this immunity will protect the individual from the other types. One can still become infected by the different types of dengue virus.

Being exposed to the dengue virus repeatedly will put one at higher risk to develop dengue hemorrhagic fever.
