This is a very common question doctors are asked during antenatal care.
Human infection occurs mainly from the ingestion of raw lamb, pork or beef.
Rarely, it can come from eating oocysts in cat feces or even water system contamination. Inside cats have almost no exposure to toxoplasmosis, but even in that case, a non pregnant person ideally should be responsible for changing the cat litter. Sometimes there are no symptoms with an infection, but when they do occur, they are mild. Tiredness, lymph node swelling, a generalized not feeling well and muscle aches are the most common, albeit nonspecific. Others are asymptomatic at birth but develop these same problems and hearing loss in early childhood.
