Toxoplasmosis

Toxoplasmosis is a common infection caused by a microscopic parasite called *Toxoplasma gondii*. While many people worldwide carry the parasite, most healthy individuals never develop noticeable symptoms because their immune system effectively keeps the infection under control. For these individuals, the infection might feel like a mild flu or go completely unnoticed. However, in certain groups, such as pregnant individuals and those with weakened immune systems, toxoplasmosis can lead to serious health problems. You can become infected in several ways. The most common routes include eating undercooked meat contaminated with the parasite, or by accidental ingestion of the parasite through contact with infected cat feces (e.g., from changing a litter box, gardening in contaminated soil, or consuming unwashed produce grown in contaminated soil). Pregnant individuals can also pass the infection to their unborn child, which is known as congenital toxoplasmosis and can lead to significant developmental and health issues for the baby. Given that many infections are asymptomatic or present with non-specific, flu-like symptoms, lab tests are essential to accurately diagnose toxoplasmosis. Testing can determine if you have a current, active infection, if you've been exposed in the past and are now immune, or if you are susceptible to infection. This information is particularly critical for pregnant individuals due to the risks to the fetus, and for people with weakened immune systems (such as those with HIV/AIDS or undergoing chemotherapy) who are at a higher risk for severe complications affecting the brain, eyes, and other organs. Your test results help your doctor determine the best course of action, which may include monitoring, preventive measures, or treatment.
