	==Virology==		==Virology==
	The tick-borne encephalitis virus is a positive-sense single-stranded RNA virus. It belongs to the family ''[[Flaviviridae]]'', which also includes other notable viruses such as the [[West Nile virus]], [[Dengue virus]], and [[Zika virus]]. TBEV is divided into three subtypes: European, Siberian, and Far Eastern, each associated with different geographical regions and clinical outcomes.

	TBE is primarily transmitted through the bite of infected ticks. The ''Ixodes ricinus'' tick is the main vector in Europe, while ''Ixodes persulcatus'' is prevalent in Asia.

	==Epidemiology==		==Epidemiology==
	TBE is endemic in many parts of Europe and Asia, with thousands of cases reported annually. The highest incidence rates are found in Russia, the Baltic states, and Central Europe. The disease is most commonly reported during the spring and summer months when tick activity is at its peak.

	==Clinical Features==		==Clinical Features==
	The clinical course of TBE can be divided into two phases. The first phase, which occurs after an incubation period of 7-14 days, is characterized by nonspecific symptoms such as fever, fatigue, headache, and muscle aches. After a brief remission, the second phase may occur, involving neurological symptoms such as meningitis, encephalitis, or meningoencephalitis. Severe cases can lead to long-term neurological sequelae or even death.		The clinical course of TBE can be divided into two phases.

	Preventive measures include avoiding tick bites by wearing protective clothing, using insect repellents, and performing regular tick checks.

	There is no specific antiviral treatment for TBE. Management is supportive and focuses on alleviating symptoms.

'''Tick-borne encephalitis''' ('''TBE''') is a [[viral infection]] that affects the [[central nervous system]]. It is transmitted by the bite of infected [[ticks]] or, less commonly, by consuming unpasteurized dairy products from infected animals.

==Transmission==
TBE is primarily transmitted through the bite of an infected tick. The ticks that carry the TBE virus are most commonly found in forested areas of Europe and Asia. In rare cases, TBE can also be contracted by consuming unpasteurized milk or cheese from infected animals.

==Symptoms==
The symptoms of TBE can vary widely, but they typically include [[fever]], [[headache]], [[nausea]], and [[muscle pain]]. In severe cases, the infection can lead to [[meningitis]], [[encephalitis]], or [[myelitis]], which can cause long-term neurological damage.

==Prevention and Treatment==
There is no specific treatment for TBE, but the symptoms can be managed with supportive care. A [[vaccine]] is available and is recommended for people living in or traveling to areas where the disease is common.
