Chikungunya is a viral infection caused by the Chikungunya virus (CHIKV), which is transmitted to humans primarily through the bite of infected Aedes mosquitoes. The mosquitoes are typically active during daylight hours, particularly after sunrise and before sunset.
Although rarely fatal, Chikungunya can cause severe joint and muscle pain that may persist for months or even years, leading to chronic discomfort or disability for those affected.
A vaccine called Vimkyunya is now licensed for use in the UK to protect adults against Chikungunya virus infection, providing an important option for travellers to high-risk areas.

Prevention
Preventing Chikungunya involves both personal protection against mosquito bites and, where appropriate, vaccination. Key preventive measures include:
While the illness is usually self-limiting, preventive actions, especially vaccination and mosquito control, play a crucial role in reducing transmission.
Countries at risk
The disease is most common in tropical and subtropical regions, including Asia, Africa, the Caribbean, and Central and South America. In recent years, cases have also been reported in Europe (France, Italy, Spain) and the United States due to the expansion of Aedes mosquito populations. In recent decades, following international spread of disease, large outbreaks have occurred in:
The presence of Aedes mosquitoes in European countries, and importations from infected travellers returning from endemic countries, means that the likelihood of Chikungunya spreading in mainland Europe is high.
Sign and Symptoms
Symptoms of Chikungunya typically appear 2–12 days after being bitten by an infected mosquito. The disease often begins suddenly and can cause significant discomfort. Common signs and symptoms include:
Most people recover fully within 1–2 weeks, but some experience long-lasting joint stiffness and pain. Severe illness is uncommon but can occur in:
There is no specific antiviral treatment. Management includes rest, fluids, and pain relief with paracetamol or other non-aspirin analgesics. Aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) should be used avoided until dengue infections are ruled out, as non-steroidal anti-inflammatory drugs (NSAIDs) can increase the risk of bleeding.
