A CLINICAL CASE OF TICK-BORNE ENCEPHALITIS IN A 6-YEAR-OLD CHILD

     Tick-borne encephalitis (TBE) is a natural focal viral infection that occurs with high fever and intoxication. It is characterized by damage to the gray matter of the brain and/or the membranes of the brain and spinal cord, with the development of meningitis, meningoencephalitis or encephalomyelitis. The disease can result in persistent neurological and psychiatric conditions, and even death. The carriers of tick-borne encephalitis are ixodid taiga ticks. This type of tick is especially proactive in the spring and summer, endangering adults and children. Infectioning of a person occurs after a tick bite. The causative agent of tick-borne encephalitis is a neurotropic, RNA-containing virus. Tick-borne encephalitis is characterized by increasing neurological symptoms. The symptoms after an encephalitis tick attack are very varied. There are 5 main forms of tick-borne encephalitis: febrile, meningeal, meningoencephalitic (occurs in 15 % of the country as a whole, and twice as often in the Russian Far East). To diagnose with tick-borne encephalitis, it is necessary to take into account clinical manifestations (damage to the central nervous system), epidemiological data (time of the year, presence of vaccination, fact of a tick bite) and laboratory methods of specific diagnosis.

     The Republic of Sakha (Yakutia) is not an endemic region for the spread of TBE. However, in recent years due to climate change, the number of ticks and bites in this area has increased. This article describes a case of TBE in a 6-year-old child. The disease was extremely severe and resulted in death. Despite the fact that TBE is an extremely rare pathology in our republic, screening for this pathology must be carried out during the tick season.
