Dengue & Chikungunya


D   E   N  G   U  E


Dengue  Hemorrhagic  fever  is  a  severe, potentially  deadly  infection  caused  by  some  mosquitos.

CAUSE:            Four different  dengue  viruses  are  known  to  cause  Dengue  Hemorrhagic fever.  Dengue hemorrhagic  fever  occurs  when  a  person  is  bitten  by  a mosquito  that is infected  with the virus. The mosquito Aedes  Aegyptis  is the main species  that  spreads  this  disease.

Symptoms :     Early  symptoms  of  the  disease    include

  • Decreased appetite
  • Fever
  • Headache
  • Joint/ Muscle pains
  • General ill  feeling
  • Vomiting

Diagnosis :   The  Dengue  fever  can  be  detected  by  doing  a  simple  blood  test.

  1. Arterial blood
  2. Blood tests ( to find  the  signs  of  virus  in the blood)
  • Coagulation studies
  1. Platelet count

Treatment:        Since  the  fever  is  caused  by  a  virus  for  which  there  is  no  cure  or  vaccine, the  only  treatment  is  to  treat  the  symptoms.  These treatments may include

  1. A  transfusion  of  fresh  blood  or  platelets  to correct  bleeding
  2. Intravenous(IV) fluids and electrolytes to correct electrolyte imbalances
  3. Oxygen therapy to treat abnormally low blood oxygen
  4. Rehydration with intravenous (IV) fluids to treat dehydration
  5. Supportive care in an intensive care unit or similar setting

  • Chikungunya is a viral disease transmitted to humans by infected mosquitoes. It causes fever and severe joint pain. Other symptoms include muscle pain, headache, nausea, fatigue and rash.
  • Joint pain is often debilitating and can vary in duration.
  • The disease shares some clinical signs with dengue and zika, and can be misdiagnosed in areas where they are common.
  • There is no cure for the disease. Treatment is focused on relieving the symptoms.
  • The proximity of mosquito breeding sites to human habitation is a significant risk factor for chikungunya.
  • The disease mostly occurs in Africa, Asia and the Indian subcontinent. However a major outbreak in 2015 affected several countries of the Region of the Americas.
