What Is Viral Encephalitis?
2. Causes
There are a number of viruses that can cause viral encephalitis. The infection tends to occur before or during the time when the patient is ill with another virus-related disease. This includes diseases like the flu, mumps, chickenpox, measles, and herpes. Among the most common culprits is the herpes simplex type 1 virus, which is responsible for herpes and cold sores.
A sub-category of viral encephalitis is arbovirus encephalitis. These are varieties of viral encephalitis that are caused by viruses that are spread by insects such as ticks and mosquitos. Arbovirus encephalitis tends to be restricted to certain regions where particular insects are found.
