A97.9: Dengue, unspecified
Dengue, specified as A97.9 in the ICD-10 WHO 2016 classification, is a viral infection primarily transmitted through the bite of an infected Aedes mosquito. These mosquitoes are typically active during the day and are prevalent in tropical and subtropical areas around the world. Once the individual is bitten, symptoms like sudden high fever, severe headache, pain behind the eyes, muscle and joint pain, rash, and mild bleeding (such a nosebleed or bleeding gums) may develop. Although referred to as "unspecified", this terminology generally encompasses all forms of dengue without other specified complications. Dengue can progress to more severe forms, such as Dengue Hemorrhagic Fever and Dengue Shock Syndrome, which can be life-threatening. There's no specific treatment for dengue, and care is typically supportive to manage symptoms.
