Crimean Congo Hemorrhagic Fever Virus Detected in French Livestock adn Wildlife, raising Concerns of Endemic Spread
Paris, France – September 25, 2025 – A new study reveals the presence of the Crimean Congo Hemorrhagic Fever (CCHF) virus in both livestock and wild animal populations across France, signaling a potential for the virus to become established within the country. Researchers, publishing their findings in PLOS One, analyzed blood samples from over 10,795 animals – 8,609 cattle and 2,186 wild animals including deer, wild boar, and foxes - detecting antibodies in approximately 2% of the animals tested.
While the prevalence remains relatively low compared to highly affected African nations like Mauritania and Mali, where infection rates can reach 70%, the findings are significant. The study highlights a growing risk as Hyalomma ticks – the primary vector for CCHF in France – continue to expand their range, likely driven by climate change.Thes ticks, relatively new arrivals to
