Tick-borne encephalitis (TBE) is a viral infection that affects the central nervous system, primarily transmitted through the bite of infected ticks. It is most common in certain regions of Europe and Asia, particularly in forested areas where ticks thrive. Symptoms can range from mild flu-like signs to severe neurological issues, including confusion and seizures. Preventive measures include vaccination for those at high risk, such as outdoor workers and travelers to endemic areas. Avoiding tick bites by wearing protective clothing and using insect repellent can also help reduce the risk of infection. Early diagnosis and treatment are crucial for better outcomes.
