Classical dengue fever is a viral illness transmitted by infected mosquitoes. It is characterized by sudden high fever, chills, severe headache, back and extremity pain, pain behind the eyes, skin rash, and mild bruising.
Medical necessity for treatment is established by the confirmed diagnosis of dengue fever. The severity of symptoms guides the intensity of treatment. Supportive care is essential for preventing complications and ensuring recovery.
The provider diagnoses dengue fever based on the patient's history of exposure, physical examination findings, and symptoms. They order laboratory tests, including a complete blood count (CBC) to check for low platelet count, and specific tests like PCR and ELISA. Treatment is symptomatic and supportive, focusing on rest, hydration, fever reduction, and pain management.
In simple words: Dengue fever, also called break-bone fever, is a virus spread by mosquito bites. It causes a sudden high fever, chills, bad headaches, and pain in the back, arms, and legs. You might also have pain behind your eyes, a rash, and some bruising. Doctors diagnose it by looking at your symptoms, travel history, and blood tests. Treatment involves rest, fluids, and medicine to reduce fever and pain.
Dengue fever (classical dengue), also known as break-bone fever, is a viral illness caused by one of four dengue virus strains (DEN-1 through DEN-4). It's transmitted to humans through the bite of infected Aedes mosquitoes, primarily Aedes aegypti.Symptoms include sudden high fever (typically lasting 3-7 days), chills, severe headache, pain in the back and extremities, retro-orbital pain (pain behind the eyes), skin rash, and mild bruising.Diagnosis involves assessing exposure history, physical examination, and symptoms. Laboratory tests like a complete blood count (CBC) may reveal a reduced platelet count.Polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA) tests can confirm the diagnosis. Treatment focuses on symptom management, including rest, fluids, antipyretics for fever, and pain relievers.
Example 1: A traveler returning from Southeast Asia presents with sudden high fever, severe headache, joint pain, and a rash. The physician suspects dengue fever and orders a CBC and PCR test. The tests confirm the diagnosis, and the patient receives supportive care, including fluids and pain medication., A patient living in a tropical region develops a high fever, muscle aches, and retro-orbital pain. They have a known mosquito bite history.The physician considers dengue and orders a CBC and ELISA test. The results indicate dengue fever, and the patient receives symptomatic treatment., A child presents with high fever, headache, and body aches.The physician conducts a physical exam and finds a rash. After obtaining a travel history to a dengue-endemic area, the doctor orders blood tests. The tests confirm dengue fever, and the patient receives supportive treatment.
Documentation should include: signs and symptoms (e.g., fever, headache, muscle and joint pain, rash), travel history to dengue-endemic areas, mosquito exposure history, laboratory test results (CBC, PCR, ELISA), and details of treatment provided.
