Chikungunya virus disease
ICD-10 A93.2 is a billable code used to indicate a diagnosis of chikungunya virus disease.
Chikungunya virus disease is an arthropod-borne viral infection caused by the chikungunya virus, 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. Symptoms typically appear 2-12 days after being bitten by an infected mosquito and can last for several days to weeks. In some cases, joint pain may persist for months or even years, leading to chronic arthralgia. The disease 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 many cases occur in individuals returning from endemic areas. Laboratory confirmation can be achieved through serological tests or PCR. While chikungunya is rarely fatal, it can lead to significant morbidity due to the debilitating nature of the joint pain. Public health measures focus on mosquito control and prevention of bites, especially in areas where the virus is prevalent.
