Acute Encephalitis is a symptom which appears in the Necroa Virus and Neurax Worm DLCs, as well as the Smallpox and Mad Cow Disease scenarios. It causes lesions in the brain, which causes lethal brain damage. This is not to be confused with the Nipah Virus-unique Encephalitis.


  • Surprisingly, Acute Encephalitis in Necroa Virus is only slightly severe.
