Dengue Fever

Dengue fever is a viral disease also known as break-bone fever. It is a very infectious disease in the Dengue Fever mosquitotropics.It is caused by the dengue virus. The signs and symptoms of this disease are headaches, fever, joint pains, and muscle pain. It has a skin rash looks that are similar to that of measles.
Another type of fever caused by the same virus is the dengue hemorrhagic fever and this is more severe than the latter. The dengue hemorrhagic fever is characterized by bleeding and low levels of blood platelets due to blood plasma leakage, and this can lead to a dangerously low blood pressure state known as Dengue Shock Syndrome.

Dengue Fever Causes

The viral disease is transmitted by a species of mosquito called Aedes Aegypti which is found in the tropical areas in the world. It is contracted through a mosquito bite. Some of the areas where this disease is common are, Sub Saharan Africa, The Caribbean, northeastern Australia, and South and Central America.
The virus has four different types and their effect on victim differ, one can give lifelong immunity to that type but a short term to others. Prevention and reducing the breeding of these mosquitoes and limiting exposure to the bite is advised as there are no vaccines available.
Oral or Intravenous rehydration is a supportive treatment for moderate fever while blood transfusion and intravenous fluids are necessary for more acute cases.

Symptoms of Dengue Fever

Majority of those who have been infected by this disease experience mild symptoms such as mild fever whereas a few others can have a life-threatening Fever. Dengue Fever incubation the period from the time of exposure is about 4 to 7 days and can span up to 14 days. Children exposed to the disease are more likely to experience severe complications.
The first symptoms of dengue disease are mild fever, headache, rash, joint, and muscle pain. Dengue Fever is also called breakbone fever because it comes with joint and muscle pain. The infection passes through 3 stages:
  • Febrile
  • Critical
  • Recovery

Dengue Fever Febrile Stage

The febrile stage is characterized by body pain and headache with high fever for about two to seven days. Skin rash also develops at the earlier stage and later results in a measles-like rash. Red spots in the skin can also be observed which when pressed can cause bleeding, Bleeding can also be seen in the mucous membrane of the mouth and nose. However, there is a variation of these symptoms from person to person.

Dengue Fever Critical Stage

In some cases, the dengue fever can advance to the critical stage where the fever advanced to high fever, this is characterized by the accumulation of fluid in the stomach region and chest the region which depletes fluid circulation in the body and causes dehydration and reduced supply of fluid by the blood to important organs in the body. Severe bleeding, organ dysfunction and shock are experienced.

Dengue Fever Recovery Stage

For about two to three days and with the disappearance of fluid into the bloodstream and increase in itching and a slow heart rate. Here there could be fluid overload which can affect the brain and may cause seizures or reduced level of consciousness.
  • Fatigue
  • Joint Ache
  • Vomiting
  • Swollen Lymph Nodes
  • Diarrhea
  • Common cold especially in children.

7 warning signs of dengue fever

The most common warning signs of Dengue Viral disease are ongoing
1.   Vomiting
2.    Liver enlargement
3.    Abdominal Pain
4.   Headache behind the eyes
5.    Lethargy
6.   Mucosal bleeding
7.    Decrease in platelets count

Test for Dengue Fever

Tests that may be done to diagnose the presence of this Dengue Fever disease includes:
  • Antibody titer for dengue virus types
  • Complete blood count (CBC)
  • Test for dengue virus type is polymerase chain reaction (PCR)

The World Health Organization classified the Dengue Fever into 3 classes are:

1.   Undifferentiated Fever
2.    Dengue Fever
3.   Dengue Hemorrhagic Fever
Dengue Hemorrhagic Fever is subdivided into grades 1-4. Grade one is characterized by the presence of easy bruising and positive tourniquet tests in a victim of fever. Grade 2 shows bleeding in the skin and other parts of the body, Grade 3 is evident by Shock and Grade 4 is a severe shock that blood pressure and the pulse becomes difficult to detect. Grade 3 and 4 is generally referred to as Dengue Shock Syndrome.

Dengue Fever Treatment 

There is no particular known treatment for the disease. Oral Rehydration Therapy is recommended for signs of dehydration. Do not take Aspirin for treatment, Acetaminophen (Tylenol) is used to treat a high fever.
Dengue Fever although very uncomfortable and weakening, it is nor a deadly disease. People with the condition usually recover fully. Prevention is the best therapy however for dengue fever.
