Encephalitis

Encephalitis is an acute infection and inflammation of the brain. Meningitis is the inflammation of the layers covering the brain.

Encephalitis is generally a viral illness. Viruses such as those responsible for causing cold sores, mumps measles and chickenpox, can also cause encephalitis. A certain family of viruses, the Arboviruses are spread by insects like mosquitoes and ticks.  Although viruses are the most common source of infection, bacteria, fungi and parasites can also be responsible.

The illness resembles the flu and usually lasts for 2-3 weeks. It can vary from mild to life-threatening, and even cause death. Most people with a mild case can recover fully. Those with a more severe case can recover although they may have damage to their nervous system. This damage can be permanent.
