New Delhi, May 17, 2020 :

Dengue is a mosquito-borne viral infection causing a severe flu-like illness and, sometimes causing a potentially lethal complication called severe dengue. The incidence of dengue has increased 30-fold over the last 50 years. Up to 50-100 million infections are now estimated to occur annually in over 100 endemic countries, putting almost half of the world’s population at risk.

Dengue Fever :

Dengue causes flu-like symptoms and lasts for 2-7 days. Dengue fever usually occurs after an incubation period of 4-10 days after the bite of the infected mosquito. High Fever (40°C/ 104°F) is usually accompanied by at least two of the following symptoms:

  • Headaches
  • Pain behind eyes
  • Nausea, vomiting
  • Swollen glands
  • Joint, bone or muscle pains
  • Rash

Severe dengue :

When developing into severe dengue, the critical phase takes place around 3-7 days after the first sign of illness. Temperature will decrease; this does NOT mean the person is necessarily recovering. On the other hand, special attention needs to be given to these warning signs as it could lead to severe dengue:

  • Severe abdominal pain
  • Persistent vomiting
  • Bleeding gums
  • Vomiting blood
  • Rapid breathing
  • Fatigue/ restlessness

When severe dengue is suspected, the person should be rushed to the emergency room or to the closest health care provider as it causes:

  • Plasma leaking that may lead to shock and/or fluid accumulation with/without respiratory distress;
  • Severe bleeding;
  • Severe organ impairment.
