Viral encephalitis is an infection leading to the inflammation of the brain, caused by a virus . It can be a serious illness that affects the brain's normal functioning and can even lead to death if not treated promptly.
It is important to note that different types of viruses, including cytomegalovirus, West Nile virus , and Epstein-Barr virus, can cause viral encephalitis. In some cases, viral encephalitis can be prevented through vaccination.
