There is no specific treatment for dengue fever. Because dengue is caused by a virus, there is no specific medicine or antibiotic to treat it, the only treatment is to treat the symptoms. For typical dengue, the treatment is purely concerned with relief of the symptoms (symptomatic). Rest and fluid intake for adequate hydration is important
For severe dengue, medical care by physicians and nurses experienced with the effects and progression of the disease can save lives – decreasing mortality rates from more than 20% to less than 1%. Maintenance of the patient’s body fluid volume is critical to severe dengue care.
After being bitten by a mosquito carrying the dengue virus, the incubation period ranges from 3 to 14 (usually 4 to 7) days before the signs and symptoms of dengue appear. Dengue occurs in two forms:
1) Dengue Fever (DF)
2) Dengue Haemorrhagic Fever (DHF)
