Chikunguyna must be differentiated from other diseases that present with flu like symptoms such as [[fever]], [[headache]], [[fatigue]], [[joint aches]] or [[arthralgias]], [[myalgias]]. Diseases with similar symptoms include [[dengue]], [[influenza]], [[measles]], [[rubella]], [[malaria]], and [[yellow fever]].

==Differential Diagnosis==
* The differential diagnosis of chikungunya [[virus]] infection varies based on place of residence, travel history, and exposures.  
* The differential diagnosis of [[Chikungunya causes|chikungunya virus]] infection varies based on the place of residence, the travel history, and the history of exposures.  
* [[Dengue]] and chikungunya viruses are transmitted by the same [[mosquitoes]] ([[Aedes aegypti]] and [[Aedes albopictus]]) and have similar clinical features.
* [[Dengue]] and chikungunya viruses are transmitted by the same [[mosquitoes]] ([[Aedes aegypti]] and [[Aedes albopictus]]) and have similar clinical features.
* The two [[viruses]] can circulate in the same area and can cause occasional co-infections in the same patient.
* The two [[viruses]] can circulate in the same area and can cause occasional co-infections in the same patient.
* Chikungunya [[virus]] infection is more likely to cause high [[fever]], severe [[arthralgia]], [[arthritis]], [[rash]], and [[lymphopenia]], while [[dengue virus]] infection is more likely to cause [[neutropenia]], [[thrombocytopenia]], [[hemorrhage]], [[shock]], and [[death]].

* It is important to rule out [[dengue virus]] infection because proper clinical management of [[dengue]] can improve outcome.

Overview

Chikunguyna must be differentiated from other diseases that present with flu like symptoms such as fever, headache, fatigue, joint aches or arthralgias, myalgias. Diseases with similar symptoms include dengue fever, influenza, measles, rubella, malaria, and yellow fever.

Differential Diagnosis

Shown below is a table summarizing the typical findings of the differential diagnoses of chikungunya.

Disease Findings
Malaria Periodic fever and altered level of consciousness
Dengue Fever Fever and two or more of the following: retro-orbital or ocular pain, headache, rash, myalgia, arthralgia, leucopenia, or hemorrhagic manifestations
Leptospirosis Severe myalgia localized to calf muscles, conjunctival congestion or subconjunctival hemorrhage, with or without jaundice or oliguria
History of contact with contaminated water
Alphaviral infections (Mayaro, Ross River, Barmah Forest, O’nyong nyong, and Sindbis viruses) Similar clinical presentation as Chikunguyna
Travel history and known areas of Mayaro in the Americas
Post-infectious arthritis (including rheumatic fever) Arthritis of one or more, typically larger joints due to an infectious disease such as Chlamydia, Shigella, and gonorrhea
Rheumatic fever is seen more commonly in children as migratory polyarthritis predominantly affecting large joints.

Consider antistreptolysin O (ASO) titer and history of sore throat with Jones criteria for rheumatic fever.
