Chikungunya Virus: A Growing Threat in Europe?
Originally discovered in Tanzania in 1952, the chikungunya virus was long considered a tropical disease. However, recent years have seen increasing outbreaks in Europe, raising concerns about its potential to become more widespread.
France and Italy Experience Rising Cases
In France, over 800 cases were reported in a single year, and Italy as well experienced hundreds of infections. These outbreaks are often initiated by infected travelers returning from tropical regions who are then bitten by local tiger mosquitoes, which subsequently spread the virus.
The Asian Tiger Mosquito: A Key Vector
A new study from the UK Centre for Ecology and Hydrology (UKCEH), published in the Journal of the Royal Society Interface, reveals that the Asian tiger mosquito can transmit chikungunya at lower temperatures than previously believed. The threshold is now estimated to be around 13–14 degrees Celsius, approximately 2.5 degrees lower than earlier estimates.
Global Warming and Extended Transmission Seasons
The effects of global warming are further exacerbating the situation. Longer and more frequent warm periods are increasing the number of weeks – and sometimes months – during which the virus can spread locally. This extends the potential transmission season, increasing the risk of outbreaks.
“For twenty years ago, everyone would have called you crazy if you had said that we would get chikungunya in Europe: it is a tropical disease. Now everything has changed,” says Steven White at UKCEH.
France-Tanzania Connections: Tourism and Trade
France maintains strong ties with Tanzania, particularly in tourism. Over 100,000 French citizens visited Tanzania in 2022, with Zanzibar being a popular destination. Air France operates flights between Paris and Zanzibar, and since June 2023, offers direct flights to two Tanzanian cities. Bilateral trade between the two countries reached approximately 136 million euros in 2020, with French exports focused on machinery, electrical equipment, and IT, even as imports from Tanzania include forestry, fish, and agricultural products.
France and Italy in the UEFA Nations League
Recent sporting events highlight the connection between France, and Italy. In a UEFA Nations League match in 2025, France initially took the lead with a goal after just 13 seconds – a record for the competition – but Italy ultimately won the game 3-1. This demonstrates the ongoing sporting and cultural exchange between the two nations.
FAQ
Q: What is the chikungunya virus?
A: A viral disease transmitted to humans by infected mosquitoes, causing fever and severe joint pain.
Q: How is chikungunya spread?
A: Primarily through the bite of infected mosquitoes, particularly the Asian tiger mosquito.
Q: What are the symptoms of chikungunya?
A: Fever, joint pain (often severe), headache, muscle pain, rash, and fatigue.
Q: Is there a vaccine for chikungunya?
A: As of February 2026, there is no widely available vaccine, but research is ongoing.
Q: What can be done to prevent chikungunya?
A: Avoiding mosquito bites through the use of repellents, wearing protective clothing, and eliminating standing water where mosquitoes breed.
Did you know? The Asian tiger mosquito is an invasive species that has rapidly expanded its range in recent decades, increasing the risk of mosquito-borne diseases in new areas.
Pro Tip: When traveling to areas with known chikungunya transmission, consult your doctor about preventative measures and be vigilant about mosquito bite prevention.
