This virus is transmitted by ticks. Breeders, hikers and hunters must be particularly vigilant.
For the first time, the Crimean-Congo hemorrhagic fever virus was detected in France in a cattle farm in the Pyrénées-Orientales.
“The Crimean-Congo hemorrhagic fever virus was detected, on October 6, 2023, in ticks of the genus Hyalomma collected from cattle raised in the Pyrénées-Orientales” indicates the site of the Coves. Numerous analyzes were carried out by the Center for International Cooperation in Agricultural Research for Development (CIRAD) and the national reference center of the Institut Pasteur confirmed the results. The detection dates back to October 6 last.
No indigenous human cases
No indigenous human cases has not yet been recorded in France, but a dozen have already been reported in Spain since 2016 including some among health professionals, underlines Public Health France.
This tick, native to Africa and Asia, was introduced mainly by migratory birds. It is present in Corse for several years and on the Mediterranean rim since 2015. Its presence is likely to expand further north in the future due to climate change.
Public health France has since taken stock of the situation and recalls the recommendations to adopt. Above all, it is regarding preventing tick bites for the breeders, farmers, hikers and all people likely to frequent places (pastures, scrubland in particular) where these ticks are found around the Mediterranean. The risk is seasonal from April to July.
Small mammals and hares
In these geographical areas, ANSES also calls on hunters to limit contact with blood and bodily fluids when skinning small mammals and in particular hares (wearing gloves and masks). In the event of a tick bite, you must monitor your general condition and consult a doctor promptly in case ofappearance of symptoms in the month following the exposure.
In humans, Crimean-Congo hemorrhagic fever is generally limited to flu syndrome with digestive problems. The symptoms appear suddenly. They can result in myalgia (muscle pain), digestive disorders, dizziness, neck stiffness and pain, back pain, headaches, eye sensitivity and photophobia (feeling of discomfort caused by light). ). In some cases, the fever can nevertheless worsen and result in hemorrhagic syndrome (potentially severe bleeding), with a risk of death of up to 30% in some countries.
The virus is not transmitted through consumption of raw milk dairy products and transmission through consumption of meat from infected animals has never been reported.
