Surge in Dengue Fever Cases in Mainland France Raises Concerns Ahead of 2024 Olympics

Record-Breaking Imported Cases

As of the start of 2024, mainland France has seen a dramatic increase in imported dengue fever cases, with 1,679 reported incidents compared to just 131 during the same period in 2023. Dr. Grégory Emery, the Director General of Health, described this situation as "unprecedented" during a recent press conference. The majority of these cases are linked to travelers from regions like the French West Indies, where the dengue virus is commonly transmitted by the Aedes albopictus mosquito.

Reflection of Wider Regional Outbreaks

Dr. Caroline Semaille, Director General of Public Health France, pointed out that the situation in France mirrors the larger dengue outbreaks occurring in the Antilles and the broader Latin America and Caribbean region. These areas have reported exceptionally high levels of dengue activity since the beginning of the year.

Demographic Details and Pre-Olympic Concerns

The data reveals that most of the imported cases since mid-2023 involve individuals returning from the French West Indies. Notably, nearly 20% of these cases are in people aged over 65, with very few cases reported in children. With the upcoming Paris Olympic Games, which coincide with the peak season for tiger mosquitoes, there is a heightened risk of further spreading the disease.

Calls for Vigilance and Preventive Measures

Authorities are urging the public to be vigilant and proactive in preventing the spread of the tiger mosquito, especially in the lead-up to the Olympics. Dr. Emery emphasized the importance of eliminating stagnant water and avoiding mosquito bites. These preventive measures are crucial as they could help prevent the establishment of local transmission chains within France.

Olympic Games Amplify Risk

The impending Olympic and Paralympic Games are expected to bring a significant influx of international visitors to France, further increasing the risk of dengue spread. Health officials are stressing the importance of heightened preventive efforts during this period to safeguard public health.
