Dengue

Introduction of Dengue infection:

Dengue is otherwise known as ‘breakbone’ fever, is one of the prevalent diseases especially in the regions of Caribbean, South America and Asia in recent times. Almost 40% of the world’s population inhabits in an area prevalent with dengue. 250,000 cases of dengue fever were reported during1995 world wide and 7,000 cases were reported in the U.S. Globally, the fatality rate of Dengue Hemorrhagic Fever is around 5%

Possible causes of Dengue fever:

  • A mosquito named Aedes aegypti (single-stranded RNA virus belonging to the Flaviviridae family has 4 distinct serotypes)
  • Secondary vector of dengue Aedes albopictus

Types of Dengue fever:

  • Acute dengue fever (39-40 degree C)
  • Dengue Hemorrhagic Fever (DHF) - resulting in circulatory failure
  • Dengue Shock Syndrome (extensive plasma leakage leading to high levels of  dehydration)

Symptoms of dengue infection:

  • Chills
  • Acute fever (a quick rise in the body temperature -about 104 degree F),
  • Severe joint pains
  • Eyes develop redness
  • Pain while moving the eyes
  • Painfulness behind their eye balls
  • Low backache
  • Intense pain in the inguinal region
  • Sore throat
  • Painful bleeding gums
  • Swelling of the lymph nodes
  • Visible rashes all over the body
  • Bradycardia (lower heart rate)
  • Defervescence (a sudden drop in the body temperature, with an abnormally profuse sweating)
  • Constipation
  • General depression

Complications of Dengue:

  • Dengue shock syndrome (children below the age of 10)
  • Epistaxis or nosebleeds
  • Myocarditis or inflamed heart
  • Pneumonia
  • Circulatory collapse

Diagnosis method of dengue fever:

The authorized practitioner checks for the symptoms of dengue, such as blood pressure, signs of bleeding in the skin or other sites, the patient’s hydration status and confirms it further by serological test after the collection of blood in 3 phases, namely, immediately after hospitalization, 14-21 days after hospitalization, and before discharge from the hospital. The suspected case of dengue is confirmed by a positive tourniquet test (where the capillary fragility is tested, which means the blood pressure cuff is inflated in- between systolic and diastolic pressure for a time of 5 minutes)

Treatment of dengue fever:

Since a virus is the cause of this fever, the treatment is on the basis of symptoms. According to the advice of the doctor a non-steroidal drug which is anti-inflammatory in action can be taken. Muscle pain can be relieved with muscle relaxants.

Prevention methods of Dengue fever:

The only prevention that is possible is to keep the infected person underneath a mosquito net, since the mosquito can transmit the infectious virus to another person. Steps are being practiced to control dengue in the endemic areas, by emptying stagnant and old water surrounding them. Personally, you can use mosquito repellant lotions or sprays with DEET as one of the ingredients.

Awareness of Dengue at a glance:

Dengue fever is transmitted by viruses that belong to a specific family and the mode of transmission is mosquitoes.

The characteristic symptoms include headache, joint pains, rash and lymphadenopathy, which is the swelling of glands.

Dengue hemorrhagic fever (DHF) mainly attacks children below 10 years. It results in circulatory collapse due to dengue shock.

Presently there is no effective vaccine against dengue infection.
