Primary Category of Dengue Infection – Ambulatory & Mild Symptoms

  • Those who are ambulatory and have mild symptoms should be reviewed daily for disease progression (Decrease white blood cell and platelet count) and should be checked for any warning signs. Patients should be encouraged to take plenty of food, ORS and fruit juices to replace water lose due to fever and vomiting.
  • Adequate fluid intake is the most important part of dengue management and it reduces significantly the risk of hospitalization.
  • Paracetamol is only safe for high fever and dengue and analgesic must be avoided. Paracetamol dosing should not be less than 6 hours.
  • Patient should be instructed to come to the hospital immediately if any of the following occur- No clinical improvement several abdominal pain persistant vomiting, cold and clammy extremities, lethargy or irritability/ restlessness, bleeding, and not passing urine for more than 4 to 6 hours.Treatment of Dengue Fever

Secondary Category of Dengue Infection – Fever with Symptoms

  • Second category of patients are those who have the warning signs of plasma leakage or bleeding, decreasing platelet count and persistent fever. These patients should be admitted and monitored daily.
  • Intravenous fluid replacement in the form of normal saline or ringer lactate should be started immediately at the rate of 5 to 7 ml /kg/hr for initial 1 to 2 hrs, then reduced to 3 to 5 ml/kg/hr for 2 to 4 hrs then reduced to 2 to 3 ml /kg/hr for 2 to 4 hrs or less according to the clinical response.
