1F57.1

ICD-11 MMS 2026-01

Meningoencephalitis due to Toxoplasma gondii

Description

A disease of the meninges and brain, caused by an infection with the protozoan parasite Toxoplasma gondii. This disease is characterised by seizures, neck pain, neurological deficits, or alterations in behaviour, cognition, or consciousness. Transmission is by haematogenous spread to the meninges and brain after direct ingestion of contaminated food, or indirect transmission by consumption of food or water contaminated with infected cat faeces. Confirmation is by detection of antibodies against Toxoplasma gondii in cerebrospinal fluid or identification of Toxoplasma gondii in cerebrospinal fluid, and advanced imaging of the nervous system.
