B00: Herpesviral [herpes simplex] infections

B00.3: Herpesviral meningitis

There are various kinds of herpes viruses. You have been infected with herpes simplex viruses. A person can be infected with herpes viruses via saliva, for example, or through sex. Some of the viruses remain in your body throughout your life. For example, if you are stressed or the defense system is weakened, the viruses can cause symptoms again.

The viruses have caused the linings of your brain to become inflamed. On the outside of the brain and spinal cord there are three thin meninges (linings). A tough meninx, the dura mater, is on the outside. Below that are two soft meninges.

When the meninges are inflamed, this can cause various symptoms. The neck is often stiff. You may find it difficult to tolerate bright light and loud noises. Sometimes you may also feel nauseated and feel like you have to vomit. Seizures are also possible or you may lose consciousness.
