For long, people have been confusing dengue with chikungunya. However, two are different from each other. The virus responsible for dengue is a flaviviridae flavivirus. Chikungunya, on the other hand, is brought about by a togaviridae alphavirus. The vector (an organism that acts as a natural carrier or host for viruses) for both the viral diseases remain the same, the female aedes aegypti mosquito, and to a lesser extent, the aedes albopictus mosquito. The chikungunya virus can also be spread through birds, cattle, and monkey.

However, in the case of high fever, a patient is given paracetamol (normally given after the first 2-3 days)
Anti-inflammatory, nonsteroidal drugs and painkillers (non-aspirin-based) are given to provide relief from joint pain
