Researchers call for toxoplasmosis to be recognized as a major health threat

A group of international researchers is urging the World Health Organization (WHO) to officially classify toxoplasmosis as a neglected tropical disease (NTD).

Caused by the parasite Toxoplasma gondii, this condition affects nearly one-third of the global population.

While many healthy people remain asymptomatic, the infection can have devastating health consequences, particularly for the immunocompromised and pregnant women.

Transmission typically occurs through contaminated food, contact with cat feces, or congenital spread from mother to fetus.

Notably, the parasite is a leading cause of vision loss due to ocular toxoplasmosis and can lead to severe birth defects.

Despite its high prevalence and burden, toxoplasmosis currently lacks the funding and public awareness seen in other diseases.

By adopting a 'One Health' approach—integrating animal, environmental, and human health strategies—researchers believe we can effectively combat this preventable condition.

Strengthening food safety and prenatal care is key to reducing transmission and protecting the most vulnerable populations from long-term neurological or visual impairment.
