Chikungunya: Understanding the virus and the importance of vaccination for travellers

The world is a vast field of exploration, but it’s also full of health risks, especially when traveling to regions where certain vector-borne diseases are endemic. One of these is Chikungunya, a virus transmitted by mosquitoes. Groupe Santé Voyage would like to inform you about this virus, and the importance of vaccination to ensure your safety when traveling.

What is Chikungunya?

Chikungunya is a viral disease that causes flu-like symptoms such as fever, joint pain, fatigue and rash. Joint pain can be particularly severe, and can persist for months or even years after the initial infection. According to the Institut national de santé publique du Québec (INSPQ), the Chikungunya virus spreads mainly in tropical and subtropical areas, making it a risk for travellers to these regions.

Virus transmission

Chikungunya virus (CHIKV) is transmitted by the bite of infected mosquitoes. These mosquitoes breed in stagnant water and are most active during the day. It is crucial to note that the virus is not transmitted from person to person, but only via these insect vectors. Travellers should therefore take precautions to avoid mosquito bites, using repellents, long clothing and mosquito nets, especially in areas where Chikungunya is endemic.

Chikungunya symptoms

After an incubation period of 2 to 12 days, infected individuals may present a variety of symptoms. The most common include:

  • High fever
  • Muscle pain (myalgia)
  • Joint pain (arthralgia)
  • Headaches
  • Skin rashes
  • General fatigue
  • Nausea

It is therefore essential to consult a healthcare professional if you develop these symptoms after traveling to a high-risk region. Although Chikungunya is not fatal, complications can sometimes arise, particularly in the form of persistent joint pain. Between 40% and 80% of sufferers will still have symptoms more than 3 months after infection. Dengue and Zika virus disease have similar symptoms to chikungunya, which can easily lead to misdiagnosis.

The arrival of the Chikungunya vaccine

In 2024, the Public Health Agency of Canada approved the first vaccine against chikungunya, IXCHIQ, developed by Valneva. This vaccine represents a major advance in the fight against this virus, which until now had no effective preventive solution. The vaccine has been designed to protect people traveling to regions where Chikungunya is endemic, thus meeting an unmet medical need.

The World Health Organization (WHO) stresses the importance of a vaccine to control the spread of the virus and reduce the burden of the disease in affected areas. Vaccination is particularly recommended for travellers to countries where Chikungunya is present, especially if they are staying for long periods or are in contact with mosquitoes. According to the WHO, chikungunya has been identified in over 110 countries in Asia, Africa, Europe and the Americas since 2004. The virus was first identified in Tanzania in 1952.

Why get vaccinated?

  1. Effective protection: IXCHIQ vaccine offers effective protection against the Chikungunya virus, reducing the risk of infection.
  2. Prevent complications: By protecting yourself against Chikungunya, you also minimize the risk of developing chronic joint pain, which can affect your quality of life.
  3. Safe travel: Vaccination means you can enjoy your travels with complete peace of mind, knowing you’re protected against this virus.
  4. Contribute to public health: By getting vaccinated, you help fight the spread of disease and protect local communities.

What are the recommendations for travellers?

Before you leave, it’s essential to consult a healthcare professional specializing in travel medicine, such as those at Groupe Santé Voyage. Here are a few additional recommendations:

  • Plan your vaccination: Ideally, consult a physician or a Groupe Santé Voyage nurse at least 4 to 6 weeks before your trip, to allow time to receive the vaccine and plan any other necessary vaccinations.
