Chikungunya is a viral illness caused by an arbovirus which is transmitted by Aedes mosquito. Fever and polyarthralgia are hallmark of this viral illness. Viral infections are generally associated with leucopenia and bacterial infections with leukocytosis. Leukemoid Reaction (LR) is defined by reactive increase in leukocyte count of more than 50,000/cu mm with increase in mature leukocytes on peripheral blood. Leukocytosis is common in Chikungunya but leukemoid reaction has not been reported in medical literature. Our patient presented with high grade fever and symmetrical polyarthritis. Blood investigation showed Leukemoid reaction and after extensive work up a diagnosis of chikungunya was made.
