Toxoplasmosis is an infection caused by a parasite called Toxoplasma gondii. This parasite can be found in cat feces, contaminated food, and soil. Most people who become infected do not show symptoms, but it can cause flu-like symptoms in some cases. Pregnant women and individuals with weakened immune systems are at higher risk for severe complications. In pregnant women, the infection can lead to serious health issues for the unborn baby, including developmental problems. Proper hygiene and cooking food thoroughly can help prevent toxoplasmosis.
