Toxoplasma parasites are single-celled organisms that can infect most warm-blooded animals, including humans. They primarily reproduce in cats and are spread through their feces. When humans become infected, the parasites can cause flu-like symptoms, muscle aches, and swollen lymph nodes. In people with weakened immune systems, such as those with HIV/AIDS or undergoing chemotherapy, toxoplasma infection can cause severe illness and even be life-threatening. Pregnant women who become infected can pass the parasite to their unborn child, which can lead to serious birth defects. Therefore, while toxoplasma parasites may not be dangerous for most healthy individuals, they can pose significant risks for certain vulnerable populations. **
