A80-A89: Viral infections of the central nervous system

A88: Other viral infections of central nervous system, not elsewhere classified

The group of conditions classified as "Other viral infections of the central nervous system, not elsewhere classified" refers to a variety of viral infections that specifically target the brain and spinal cord, collectively known as the central nervous system. These infections can occur when a virus invades the body and then travels into the central nervous system, or when it reactivates from a latent state inside the body. The ways in which these viruses enter the body can vary, but common methods include contact with an infected person’s bodily fluids, insect bites, or inhalation of airborne viruses. Symptoms of these infections can range widely but may include headache, fever, confusion, and various neurological symptoms such as weakness or abnormal sensations. Disease progression can also vary with some infections clearing up relatively quickly while others can become chronic and potentially lead to serious complications such as brain damage or death.
