A total of 62 confirmed cases of TBE where identified in France during 2024, a considerable jump from both 2023 and 2022 figures, marking the first full year of mandatory reporting. The majority of those affected are middle-aged, with an average age of 51 years. The period between July and August saw the highest concentration of reported cases, accounting for 53% of the total.
Symptom Presentation and Severity
Nearly half (45.2%) of the reported cases initially presented with non-specific infectious symptoms. A substantial number, 38.7%, were diagnosed with meningitis, while 45.1% exhibited encephalitis or meningoencephalitis. Notably, the increase in reports centers on more severe forms of the disease, which experts suggest reflects improved awareness among both medical professionals and the public regarding mandatory reporting protocols.
Geographical Distribution of Infections
the vast majority – 88.7% – of infections were acquired within France, primarily in the Auvergne-Rhône-Alpes and Grand Est regions. A smaller percentage, 8%, were linked to travel within Europe, with cases reported among individuals who had visited Germany, Estonia, the Czech Republic, Italy, Slovenia, albania, or Croatia. Sixteen cases (25.8%) involved individuals in professions with a heightened exposure risk to tick bites.
Localized Outbreak in Haute-Savoie
Health authorities have identified a cluster of 11 cases in the Haute-Savoie department, concentrated in an area between Thônes and Annecy. Six of these cases were linked to individuals working as breeders. All affected individuals either resided in, visited, or hiked within this well-defined area, where previous cases have also been documented. Two individuals presented with encephalitis, and four presented with meningitis.
| Year | Number of Cases | % Change from Previous Year |
|---|---|---|
| 2022 | 35 | – |
| 2023 | 39 | 11.4% |
| 2024 | 62 | 58.9% |
Did You Know? TBE is not transmitted from person to person, but exclusively thru tick bites.
preventative Measures and Recommendations
Public health officials strongly emphasize the importance of preventative measures to minimize the risk of TBE infection and other tick-borne diseases. These include wearing long clothing, applying tick repellent, staying on marked trails, and carefully inspecting your body for ticks after spending time outdoors. Should a tick bite occur, it should be removed promptly and correctly using fine-tipped tweezers or a specialized tick removal tool.
Pro Tip: When removing a tick, grasp it as close to the skin’s surface as possible and pull upward with steady, even pressure. Avoid twisting or crushing the tick.
Understanding tick-Borne Encephalitis
Tick-borne encephalitis is a viral disease that affects the central nervous system. While many infections are mild or asymptomatic, a significant proportion can led to serious neurological complications, including meningitis and encephalitis. The virus is primarily transmitted through the bite of infected ticks, particularly the Ixodes ricinus species, commonly found in forested areas and meadows. the disease is endemic in many parts of Europe and Asia, and its incidence is increasing due to factors such as climate change and changing land use patterns.
Vaccination against TBE is available in several european countries and is recommended for individuals at high risk of exposure, such as those who live in or frequently visit endemic areas. The vaccine is highly effective in preventing severe disease,but it does not eliminate the risk of infection altogether. Continued vigilance and preventative measures remain crucial for protecting against TBE.

France Reports 62 Cases of Tick Encephalitis in 2024: Understanding the Spread and Impact of the Disease
What is Tick-Borne Encephalitis (TBE)?
Tick-borne encephalitis (TBE), also known as European tick-encephalitis, is a viral disease transmitted to humans by ticks. The virus primarily affects the central nervous system and can cause a range of symptoms, from mild flu-like illness to severe neurological complications.Understanding TBE symptoms and tick bite prevention is crucial, especially as the geographical range of the disease expands. The primary vectors are Ixodes ricinus ticks, common throughout Europe and Asia.
the 2024 surge in France: A Closer Look
In 2024, France reported 62 confirmed cases of TBE, a significant increase compared to previous years. This rise is prompting public health officials to investigate the factors contributing to the spread and to reinforce TBE awareness. The affected regions are primarily located in eastern and central France, including areas like the Grand Est, bourgogne-Franche-Comté, and Auvergne-Rhône-Alpes. This increase highlights the growing importance of tick-borne disease surveillance in Europe.
Geographical Expansion: Historically, TBE was concentrated in specific areas. The recent cases demonstrate a clear expansion of the disease’s reach.
Environmental Factors: Changes in climate, land use, and animal populations (notably rodents and birds which act as reservoirs for the virus) are believed to be contributing factors.
Increased Awareness & Testing: Improved diagnostic capabilities and increased awareness among healthcare professionals may also contribute to the higher number of reported cases.
Symptoms of Tick-Borne Encephalitis: Recognizing the Signs
TBE presents in two phases. Recognizing these phases is vital for prompt diagnosis and treatment.
Phase 1 (Early Phase): Typically appears 4-7 days after a tick bite.
Fever
Headache
Muscle aches (myalgia)
Fatigue
Loss of appetite
These symptoms are often mild and can be mistaken for the flu.Approximately 90% of infections are asymptomatic.
Phase 2 (Late Phase): Develops in about 20-30% of patients, usually 1-2 weeks after the initial symptoms subside. this phase can be severe.
Meningitis: Inflammation of the membranes surrounding the brain and spinal cord.
Encephalitis: Inflammation of the brain itself.
Neurological Complications: These can include paralysis, seizures, speech difficulties, and cognitive impairment. Long-term neurological sequelae are possible in some cases.
Diagnosis and Treatment of TBE
Diagnosing TBE involves a combination of clinical assessment, patient history (including potential tick exposure), and laboratory tests.
Blood Tests: Detect the presence of antibodies against the TBE virus.
cerebrospinal Fluid (CSF) Analysis: Examines the CSF for signs of inflammation and the presence of antibodies.
PCR Testing: Can detect the virus’s genetic material in CSF or blood.
Currently, there is no specific antiviral treatment for TBE. Treatment focuses on supportive care to manage symptoms and prevent complications. This includes:
Hospitalization for severe cases.
Pain management.
Fluid and electrolyte balance.
Respiratory support if needed.
prevention Strategies: Protecting Yourself from TBE
Prevention is the moast effective way to avoid TBE. Here are key strategies:
Tick Bite Prevention:
Wear long sleeves and pants when in wooded or grassy areas.
Use insect repellent containing DEET, picaridin, or IR3535.
Tuck pants into socks or boots.
Walk in the center of trails.
Tick Checks: thoroughly check your body for ticks after spending time outdoors, paying attention to areas like the scalp, armpits, groin, and behind the knees.
safe Tick Removal: Use fine-tipped tweezers to grasp the tick as close to the skin as possible and pull upward with steady, even pressure. Avoid twisting or crushing the tick.
Vaccination: A TBE vaccine is available in several European countries and is highly effective in preventing the disease. Consider vaccination if you live in or travel to endemic areas. TBE vaccine availability varies by region.
