Chikungunya fever is an acute illness caused by chikungunya virus (CHIKV) belonging to the Alphavirus genus of the Togaviridae family. The virus is transmitted by mosquitoes, mostly Aedes aegypti and Aedes albopictus. Chikungunya fever is primarily tropical disease occurring in Africa, Asia and Indian Ocean islands. From the arrival of the Chikungunya virus (CHIKV) in the Americas in 2013 until March 2016, approximately two million cases of the disease have been reported. In Brazil, the virus was first identified in 2014 and thousands of people have been affected. It is also not uncommon in Bangladesh. In 2008, 2009, 2011, 2014, 2016 and also 2017, several sporadic cases have been reported from different parts of the country. So, burden of Chikungunya virus infection is increasing day by day. This fever is highly symptomatic; characterized by fever, petechial or maculopapular rash and severe arthralgia and arthritis. The disease is self–limiting but a part of the patients suffers from a long–lasting arthritis similar to rheumatoid arthritis. On the other side, it is difficult to distinguish chikungunya and dengue based on clinical findings alone. Both the viruses transmitted by the same mosquitoes. So, underdiagnosis or misdiagnosis of chikungunya everywhere.  To prevent further outbreak, awareness by the medical personnel, minimizing the vector density and taking appropriate control measures in the hospital setting is crucial.
