Chikungunya is a mosquito-borne viral disease caused by the chikungunya virus (CHIKV), an RNA virus in the alphavirus genus of the family Togaviridae. The name chikungunya derives from a word in the Kimakonde language, meaning “to become contorted”.
CHIKV was first identified in the United Republic of Tanzania in 1952 and subsequently in other countries Africa and Asia (1). Urban outbreaks were first recorded in Thailand in 1967 and in India in the 1970s (2). Since 2004, outbreaks of CHIKV have become more frequent and widespread, caused partly due to viral adaptations allowing the virus to be...
Chikungunya virus is transmitted by mosquitoes, most commonly Aedes (Stegomyia) aegypti and Aedes (Stegomyia) albopictus, which can also transmit dengue and Zika viruses. These mosquitoes bite primarily during daylight hours. They lay eggs in containers with standing water. Both species feed outdoors, and Ae. aegyptialso feeds indoors. When an unin...
In symptomatic patients, CHIKV disease onset is typically 4–8 days (range 2–12 days) after the bite of an infected mosquito. It is characterized by an abrupt onset of fever, frequently accompanied by severe joint pain. The joint pain is often debilitating and usually lasts for a few days but may be prolonged, lasting for weeks, months or even years...
Chikungunya virus may be detected directly in blood samples collected during the first week of illness using tests such as reverse transcriptase–polymerase chain reaction (RT–PCR). Other tests can detect a person’s immune response to chikungunya virus infection. These are typically used after the first week of infection to test for antibodies to th...
The clinical management includes addressing fever and joint pain with anti-pyretics and optimal analgesics, drinking plenty of fluids and general rest. There is no specific antiviral drug treatment for CHIKV infections. Paracetamol or acetaminophen are recommended for pain relief and reducing fever until dengue infections are ruled out, as non-ster...
Prevention of infection by avoiding mosquito bites is the best protection. Patients suspected of having CHIKV infection should avoid getting mosquito bites during the first week of illness to prevent further transmission to mosquitoes, who may in turn infect other people. The main method to reduce transmission of CHIKV is through control of the mos...
WHO supports countries to conduct surveillance and control of arboviruses through the implementation of the Global Arbovirus Initiative. WHO responds to chikungunya in the following ways: 1. supporting countries in the confirmation of outbreaks through its collaborating network of laboratories; 2. providing technical support and guidance to countri...
May 15, 2024 · Chikungunya virus is an alphavirus, similar to Mayaro and Ross River viruses. Chikungunya virus is primarily transmitted to people through the bite of an infected mosquito, mainly Aedes aegypti and Ae. albopictus. Humans are the primary hosts of chikungunya virus during epidemic periods. Bloodborne, intrapartum, and in utero transmission of ...
Chikungunya virus is spread to people by the bite of an infected mosquito. Outbreaks have occurred in Africa, the Americas, Asia, Europe, and islands in the Indian and Pacific Oceans. There is a risk the virus can spread to unaffected areas by infected travelers. The most common symptoms of chikungunya are fever and joint pain.

May 6, 2024 · What causes chikungunya? Getting bitten by a mosquito that’s infected with the virus causes a person to get the virus. The virus spreads through mosquito bites, not from person to person through bodily fluids or contact. This means if you’re sick with chikungunya, you won’t pass it on to a caregiver or family member.
