What is Toxoplasma gondii known to cause in humans?

Toxoplasma gondii is a protozoan parasite that is known to cause primarily asymptomatic infections in healthy individuals. Most people who are infected with T. gondii may not exhibit any symptoms or may experience mild flu-like symptoms, which often go unnoticed. This characteristic makes the parasite particularly interesting in the field of public health, as many cases remain undiagnosed.

Asymptomatic infections imply that while the parasite can reside in the human body, it often does not result in significant health issues for those with a healthy immune system. However, it can cause serious complications in immunocompromised individuals, such as those with HIV/AIDS, or in pregnant women, where it can lead to congenital toxoplasmosis. Understanding this aspect of Toxoplasma gondii is crucial for recognizing its potential risk factors and implications for specific populations.

The other choices suggest various health issues that do not align with established knowledge about Toxoplasma gondii, emphasizing the importance of differentiating between its symptomatology and effects on different individuals based on their health status.
