Chikungunya is a non-fatal, febrile disease that resembles dengue. Considered to be a major public health threat, this disease occurs especially in parts of Africa, India and southeastern Asia. Chikungunya virus causes clinical illness in 72-92 percent of infected human beings.
The name chikungunya is derived from the Makonde word meaning "that which bends up" in reference to the stooped posture developed as a result of the arthritic symptoms of the disease.
Just like the most dreaded dengue, chikungunya is also a mosquito-borne viral disease.
Humans and other primates are the natural hosts for the chikungunya virus (CHIKV), which is an RNA virus that belongs to the alphavirus genus of the family Togaviridae.
The virus is spread to humans by the bite of an infected female Aedes species mosquito – Aedes aegypti or Aedes albopictus.
CHIKV can cause acute, sub-acute, and chronic disease.
Chikungunya is rarely fatal, but the symptoms can be severe, long-lasting, and debilitating.
The disease shares some clinical signs with Zika, and can be misdiagnosed in areas where they are common.
Symptoms usually begin 3–7 days after being bitten by an infected mosquito. The most common symptoms are fever and joint pain.
Other signs and symptoms may include fatigue, muscle pain, swollen joint, headache and rash.
Never take this painful disease lightly, because its symptoms can have long-term implications.
Rash Due to Chikungunya
People affected by the chikungunya fever would be unable to carry out normal activities for a long period, like they cannot lift or hold anything with hands, and also complain of joint pains.

VIDAS®Anti-CHIKUNGUNYA IgM and Anti-CHIKUNGUNYA IgG by bioMérieux, a world leader in the field of in vitro diagnostics, can detect Chikungunya infection during the acute phase and into the chronic phase.
There is no real treatment for chikungunya. Most people get better on their own and recover completely.
Doctors recommend rest and prescribe medicines (like acetaminophen (Tylenol®) or paracetamol) that reduce fever and pain. It is important to drink plenty of fluids.
Using the body’s own machinery to produce antibodies against chikungunya by using mRNA may be a powerful way to combat the virus.

Valneva’s single-shot chikungunya vaccine candidate, VLA1553, offered a very high level of seroprotection in all adults, including the elderly, in March 2022.
Keep proper hygiene around. Cover the nose while sneezing. Stay protected from mosquitoes. Use mosquito repellents.
Sporadic rain results in waterlogging in several places that turn into breeding grounds for Aedes aegypti and Aedes albopictus.
Stop water stagnation. Keep the skin covered as much as possible. Wear full sleeve clothes all the time.
In May 2019, researchers at Washington University School of Medicine in St. Louis snapped high-resolution pictures of chikungunya virus latched onto a protein found on the surface of cells in the joints. This is an important milestone in chikungunya research.
