A Surge in Chikungunya Spanning 40 Countries and Four Continents
A marked increase in chikungunya virus (CHIKV) infections has been observed globally since 2025, with over 502,000 cases across 40 countries in the Americas, Africa, Asia, and Europe, including local transmission in France and Italy.
Six countries are currently experiencing above-average incidence:
- Bolivia (6,600+ cases, mainly in Cochabamba and Santa Cruz)
- Cuba (115+ cases throughout the country)
- French Guiana (500+ cases, mainly in western coastal areas)
- Mayotte (3,600+ cases throughout the country — outbreak has yet to peak)
- Seychelles (cases increasing but undisclosed, with 70+ cases reported in travelers)
- Suriname (1,360+ cases throughout the country — outbreak has yet to peak, with case numbers likely underestimated)
Notably, Bolivia has recorded 6 deaths and Mayotte 230 deaths, representing the highest mortality among affected destinations. The Americas continue to carry the highest overall burden, with Suriname alone reporting over 1,700 new cases in the past 30 days.
What This Means for Travelers
Vaccination against chikungunya (VIMKUNYA™) is recommended for travelers aged 12 years and older visiting Bolivia, Cuba, French Guiana, Mauritius, Mayotte, Seychelles, or Suriname. For destinations with sporadic cases, vaccination may be considered for those planning stays of six months or longer. Regardless of destination, all travelers should practice strict mosquito bite prevention — Aedes mosquitoes bite primarily during daylight hours, with peak activity at dawn and dusk. Book a consultation with TravelBug before your trip to ensure you have the most current recommendations for your itinerary.
