Tick-borne Encephalitis is a disease involving the central nervous system. The disease may have a different course, from a mild one – the sick person only go through the first stage of the disease, to a serious one with long-term neurological effects. In its initial stage the disease cannot be diagnosed because its symptoms are similar to those of flu.
The first phase of the disease lasts for about a week. Sample symptoms are: fever, tiredness, headaches, and muscular pain. The first phase is followed by an asymptomatic period, the patient feels well. However, later it may be followed by the second stage of the disease. Symptoms: headaches, fever, vomiting, nausea, loss of consciousness and a syndrome of meningitis or encephalitis.
Getting over tick-borne encephalitis may lead to disturbances in the mental sphere: depression, neurosis, psychogenic syndromes. One may also experience personality changes such as: excessive criticism, mistrust, aggression as well as attention disorder, insomnia.
The most frequent way of infecting a human is a bite of an infected tick. Infecting through oral route is also possible – after consumption of unpasteurized goat’s milk, sheep’s milk or cow’s milk. Anyone can fall ill and at any age. The virus is transmitted within the first few minutes of sucking of blood by a tick. Removing of a tick cannot therefore constitute an effective protection against the virus causing tick-borne encephalitis. A preventive vaccination against tick-borne encephalitis effectively prevent being taken ill.
