In the case of dengue, a high fever of 104 F is accompanied by two of the following symptoms: severe headache, pain behind the eyes, muscle and joint pain, nausea,
Vomiting, swollen glands and skin rash.
The first 2-7 days of infection are called the febrile phase.
The patient may enter the acute phase of infection after 3-7 days of illness, during which the patient’s overall symptoms may worsen.
“Severe dengue is a potentially fatal complication due to plasma leakage, fluid accumulation, respiratory distress, severe bleeding or organ loss,” warns the WHO. Warning signs during this phase are: severe abdominal pain, persistent vomiting, rapid breathing, bleeding gums or nose, fatigue, restlessness, liver enlargement, and blood in the vomit or stool.
