Dengue Phato
Dengue hemorrhagic fever, also called breakbone fever, is caused by a virus found in tropical and subtropical areas and transmitted by a mosquito bite. Incubation is usually 3 to 6 days after the bite. Signs and symptoms include fever, severe joint and muscle pain, and rash. Dengue hemorrhagic fever (DHF) is a more severe presentation of dengue fever caused by the same mosquito bite.
A strain of Arbovirus caused Dengue Hemorrhagic Fever and transmitted by the Aedes aegypti mosquito.
Characteristics of an Aedes aegypti mosquito: 1. Daybiting 2. Low-flying 3. Live in stagnant water 4. In urban area
Additional Signs and Symptoms 1. Rapid deterioration Deterioration occurs after 2–5 days of the typical symptoms of dengue fever 2. Irritability Associated with rapid deterioration 3. Restlessness Associated with rapid deterioration 4. Low blood pressure Related to hemorrhage 5. Weak and rapid pulse Related to hemorrhage 6. Petechial rash Related to hemorrhage
Stages of Dengue Hemorrhagic Fever • Grade I: fever + Herman's sign (flushes and redness of skin with lighter color at the center of the rash) • Grade II: Grade I symptoms + bleeding (epistaxis or nosebleeding, gingival bleeding, hematemesis or upper gastrointestinal bleeding; e.g: vomiting of blood), and melena or dark stool. • Grade III: Grade II + Circulatory Collapse (hypotension, cold clammy skin and weak pulse) • Grade IV: Grade III + Shock.
Diagnostic Tests and Management 1. Complete blood count to detect elevated white blood cell count, decreased platelet count (thrombocytopenia), and increased hematocrit. 2. Blood test for antibodies. 3. Ask the client about a history of travel to tropical or subtropical areas. 4. Do not give Aspirin because it contains at antiplatelet property which prmotes bleeding. 5. Treatment is solely supportive and includes: • Fluids. • Analgesics (not aspirin) for fever and muscles
