A80-A89: Viral infections of the central nervous system

A84: Tick-borne viral encephalitis

Tick-borne viral encephalitis represents a group of serious illnesses that are primarily transmitted through the bite of an infected tick. These pathogens specifically target the brain and nervous system, resulting in inflammation – a condition known as encephalitis. Typically, individuals infected with tick-borne encephalitis may experience symptoms like headache, fever, nausea, muscle pain, and in severe cases, loss of coordination or confusion. The progression of the disease can be quite abrupt, often heightening in severity over the course of a few days. It's important to note that not all tick bites will result in infection. The likelihood depends on geographic location and the type of tick, as only certain species carry the virus. Despite its potential severity, many people with tick-borne encephalitis recover completely. However, in some cases, neurological effects may be long-lasting.
