Toxoplasmosis can be transmitted from person to person. There are two types of human-to-human transmission here. One is when a pregnant woman is infected with toxoplasmosis and then passes it on to her fetus through the placenta, which directly affects the growth and development of the fetus and leads to severe malformations. The chance of this transmission is about 40%. It is called congenital route of infection. There is also a human-to-human transmission that can occur through organ transplantation and blood transfusion. The main route of toxoplasmosis infection is through animals, especially felines infected with Toxoplasma gondii. Its feces contain oocysts, and contact with food and water contaminated with oocysts, and contact with damaged skin and mucous membranes are the main sources of infection of this disease. The main way of human infection is through food transmission, eating uncooked eggs, meat, dairy products containing Toxoplasma gondii. This is called the acquired route of infection.
