O'nyong-nyong fever
ICD-10 A93.1 is a billable code used to indicate a diagnosis of o'nyong-nyong fever.
O'nyong-nyong fever is a viral disease caused by the O'nyong-nyong virus, which is transmitted primarily by the bite of infected mosquitoes, particularly Aedes species. The disease is characterized by sudden onset of fever, severe joint pain, and rash, which can last for several days to weeks. The fever typically lasts for about 3 to 10 days, and the joint pain can persist for months or even years after the initial infection. O'nyong-nyong fever is endemic in certain regions of Africa, particularly in areas with a history of outbreaks. The disease is often confused with chikungunya fever due to similar clinical presentations. Diagnosis is primarily based on clinical symptoms and travel history, particularly in patients returning from endemic areas. Laboratory confirmation can be achieved through serological tests or PCR. While the disease is generally self-limiting, supportive care is essential for managing symptoms. Understanding the epidemiology and transmission dynamics of the virus is crucial for prevention and control measures, especially in travelers to endemic regions.
