Symptoms¶
virus replicates in lymph nodes and circulation in blood affecting many cells - Fever - malaise - Myalgia - Bone break pain - rash

Categories of dengue fever¶
- Without serious symptoms
- fever ,nausea,leukopenia,rash Or
- fever + positive torquing test
- with serious symptoms
- above with abdominal pain/tenderness,hepatomegaly..etc…
- severe symptoms
- Sever plasma leakage Or
- respiratory distress
Pattern of disease¶
- Febrile phase
- Critical phase(increased vascular permeability,increased hematocrit]
- Convalesce phase

Treament¶
- Indetify the phase of infection and stage of disease progression
- Intra-venous supportive therapy for shock
- Avoid aspirin/Ibufropin which worsen the hemorrhage
- Mosquito Controll
