Chikungunya is caused by an arthropod-borne alphavirus transmitted by the mosquito vectors Aedes aegypti and Aedes albopictus.[1] It is being increasingly reported in India in general and Mumbai in particular. The name chikungunya is derived from an African language and means “that which bends up” or “A disease that makes one walk with a stooped gait” because of the incapacitating arthralgia by the disease. The usual presentation is with inflammatory arthritis/polyarthralgia. Systemic manifestations are rare. In this report, we present a case of chikungunya with pulmonary manifestations, which is very unusual. A 69-year-old male patient with laboratory-confirmed reverse transcription-polymerase chain reaction (RT-PCR) chikungunya fever had lung involvement with acute hypoxemia and electrolyte imbalance. Initially, the patient was suspected to have COVID-19 disease as there was a fever with respiratory involvement, and he had presented right in the middle of a COVID-19 pandemic. Bilateral basal crackles and low SpO2 pointed toward the same. However, TruNAAT-COVID (once), rapid antigen test-COVID (once), and RT-PCR for COVID-19 (twice) were negative. Moreover, his upper respiratory tract Multiplex PCR panel was also negative, thereby truncating the possibility of infection with usual/other viruses. Hence, all the clinical features, X-ray, and high-resolution computed tomography of the chest pointed toward pulmonary involvement because of chikungunya, making this a very unusual presentation.
