Atypical Chikungunya Presentation: Case Report From the UAE

A 64-year-old man in the United Arab Emirates presented with an atypical manifestation of chikungunya, according to a case report published on Cureus on August 18, 2026. The patient’s unusual clinical course highlights diagnostic challenges associated with the mosquito-borne virus, which typically causes sudden fever and severe joint pain but can occasionally present with less common symptoms.

Clinical Presentation and Diagnosis in the UAE Case

Medical documentation from the Cureus report details the diagnostic process for the 64-year-old patient treated within the UAE healthcare system. Clinicians evaluated the man after he exhibited symptoms that deviated from the classic presentation of chikungunya virus infection. While standard cases are easily recognized by debilitating polyarthralgia and high fever, atypical cases can mimic other tropical or viral illnesses, complicating timely identification.

According to the published findings, healthcare providers relied on laboratory testing to confirm the diagnosis. The case underscores the necessity for physicians in non-endemic or transit-heavy regions like the UAE to maintain vigilance regarding vector-borne diseases. Atypical symptoms can involve neurological, dermatological, or cardiac manifestations, which require specialized clinical management distinct from routine supportive care for joint pain.

Public Health Context of Chikungunya

Chikungunya virus is primarily transmitted to humans by infected Aedes mosquitoes, notably Aedes aegypti and Aedes albopictus. The disease is endemic in parts of Africa, Asia, and the Indian subcontinent, though travel-associated cases frequently appear globally. Public health authorities emphasize that international travel and global trade contribute to the sporadic detection of arboviruses in regions outside their traditional transmission zones.

Medical literature frequently documents rare complications of the virus, particularly among older adults or patients with underlying health conditions. Age-related vulnerability can alter the body’s immune response, potentially driving the atypical disease manifestations observed in this 64-year-old patient. Documented case reports serve to educate clinicians on expanding differential diagnoses when patients present with unusual systemic symptoms following travel or exposure in affected areas.
