One of the most dangerous types of fever is the dengue fever. This is a life-threatening condition that is caused by infection of the dengue virus. The virus spreads through the bite of mosquitoes of the Aedes genus. The most common carrier of dengue virus is the mosquito Aedes aegypti. There are four different types of dengue virus. When one is infected with a particular type of dengue virus, the person develops life long immunity against that particular virus. However, there is no vaccine to prevent dengue fever. There are different types that develop after infection with the virus. These different types exhibit different symptoms.
How Many Types Are There?
Dengue fever is caused by four different types of viruses. These viruses include Dengue 1, Dengue 2, Dengue 3 and Dengue 4. When a person is infected with dengue, it results in bleeding from the gums, nose as well as skin. A person can develop different types. When a person suffers from bleeding, he is said to be suffering from dengue hemorrhagic fever (DHF). When a person goes into shock, he is said to be suffering from dengue shock syndrome (DSS). If a person is infected with one type of virus and develops infection from a second type of virus, he is said to be suffering from dengue hemorrhagic fever with severe shock. Thus, there are 3 types that a patient can develop.
When a person develops sudden high fever of about 103 to 105°F along with severe headache, pain behind eyes, skin rash, nausea and vomiting, dengue is suspected. The fever tends to last for 5 to 7 days and comes back after 3 to 4 days. The characteristics of dengue fever make it easier to distinguish it from other fevers. These characteristics include the symptoms mentioned earlier as well as muscle and joint pains. The muscle and joint pains give rise to the term breakbone fever, for this tropical disease. Let us have a look at each of the types and know more about the symptoms associated with it.
☛ Classical Dengue Fever
Also called simple dengue fever, it does not lead to any complications. The symptoms are exhibited after 5 to 6 days of infection. The rash tends to get healed completely, but there may be a recurring episode of the rash in some cases. The symptoms of this type are as follows -
  • Sudden onset of high fever (up to 105°F) with severe chills
  • Severe headache (especially in the forehead)
  • Severe muscle and joint pain
  • Pain behind the eyeballs (especially after eyeball movement or pressing of the eye)
  • Extreme weakness in the body
  • Loss of appetite
  • Nausea
  • Change of taste in mouth
  • Abdominal pain
  • Pain in throat
  • Typical rash on skin that has a mild flushing appearance, along with mottling or tiny eruptions on the face, neck, chest, limbs and back
☛ Dengue Hemorrhagic Fever (DHF)
The dengue hemorrhagic fever is the fatal dengue fever type. It leads to complications in the vascular system. These complications cause excessive bleeding from various parts of the body. Symptoms of DHF are as follows -
  • Fever of about 105°F
  • Bleeding from the nose, gums, in vomit, blood in stools, bleeding spots on skin causing bluish black spots
  • Positive tourniquet test
  • Acute joint pain
  • Nausea and vomiting
  • Rash on chest and limbs
  • Blood vessels and lymphatic vessels malfunctioning
☛ Dengue Shock Fever
The dengue shock fever is commonly seen in children and teenagers. It is one of the most fatal types. The symptoms include -
  • High fever up to 104 to 105°F
  • Pain behind the eyes
  • Severe headache
  • Severe joint pain
  • Nausea and vomiting
  • Patient appears very restless
  • Skin is clammy and cold, even in case of high fever
  • Patient loses consciousness
  • Internal bleeding from blood vessels
  • Low blood pressure leading to shock
There is no specific treatment for dengue fever. The treatment involves management of the symptoms exhibited. This includes administration of intravenous fluids or oral rehydration therapy. The patient is given pain killers and asked to take plenty of rest. In case of severe complications, the patient is admitted to the hospital. After about a few weeks, most patients recover completely without suffering from any complications. Medical attention is very important to prevent the disease from turning into a life-threatening complication.
Simple dengue fever does not lead to any complications and is not considered to be a life-threatening infection. But, if it develops into a hemorrhagic fever or the patient goes into a shock, it could turn fatal. If one develops sudden high fever, with headache, chills, joint pain and other symptoms mentioned above, seek medical attention immediately.
