Chikungunya virus disease
ICD-10 A92.4 is a billable code used to indicate a diagnosis of chikungunya virus disease.
Chikungunya virus disease is an arthropod-borne viral infection primarily transmitted to humans through the bite of infected Aedes mosquitoes, particularly Aedes aegypti and Aedes albopictus. The disease is characterized by an abrupt onset of fever, severe joint pain, and rash. Other symptoms may include headache, muscle pain, and fatigue. The joint pain can be debilitating and may persist for weeks to months, leading to significant morbidity. Chikungunya is endemic in tropical and subtropical regions, and outbreaks have been reported in Africa, Asia, Europe, and the Americas. Travel history is crucial in diagnosing chikungunya, as it helps to identify potential exposure to the virus. Laboratory confirmation can be achieved through serological tests or PCR, but clinical diagnosis is often based on symptomatology and travel history. The disease is generally self-limiting, with supportive care being the mainstay of treatment. However, in some cases, chronic joint pain may develop, necessitating further medical intervention.
