ICD-11

A disease caused by an infection with the protozoan parasite Toxoplasma gondii. This disease is characterised by fever, lymphadenitis, sore throat, or rash. Transmission is by direct ingestion of contaminated food, indirectly by food or water contaminated with infected cat faeces, or vertical transmission. Confirmation is by detection of antibodies against Toxoplasma gondii, or identification of Toxoplasma gondii in tissue, cerebrospinal fluid, blood, or other body fluids.

Toxoplasmosis is caused by infection with Toxoplasma gondii, an obligate intracellular parasite. The infection produces a wide range of clinical syndromes in humans, land and sea mammals, and various bird species. T gondii infects a large proportion of the world's population but uncommonly causes clinically significant disease. However, certain individuals are at high risk for severe or life-threatening toxoplasmosis. Individuals at risk for toxoplasmosis include fetuses, newborns, and immunologically impaired patients.

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.
