Cat-borne parasite infection that can cause blindness affects a third of the world's population, study finds

A concerning new study indicates that a significant portion of the global population, potentially one-third, may be infected with a parasite commonly spread by cats. This infection, known as toxoplasmosis, poses a serious risk to vision, with the potential to damage the eye's retina and lead to complete blindness.

While toxoplasmosis is both preventable and treatable, experts are raising alarms about the lack of public awareness and discussion surrounding the disease. The full extent of its prevalence has only recently come to light, suggesting a widespread issue that has been largely underestimated.

The parasite can cause severe damage to the retina, a critical part of the eye responsible for processing light and transmitting visual information to the brain. This damage can ultimately result in irreversible vision loss, highlighting the urgent need for greater attention to this public health concern.
