You can keep a pet if you are pregnant, but you should be careful to make sure that the pet does not have parasitic infections, etc., because it is possible that a pregnant woman may be infected with Toxoplasma gondii or Campylobacter, or that allergies and scratches and bites may occur. 1. Toxoplasmosis: Families with dogs don’t need to worry too much because even if the dog is infected with Toxoplasma, the dog is not the final host, so the oocysts of Toxoplasma cannot be expelled at all. Families with cats need to pay attention to the fact that the Toxoplasma oocysts discharged by infected cats will remain in the natural environment for a long time, and people who accidentally eat cat feces may be infected, and the infection can be transmitted to the fetus through the placenta, resulting in miscarriage, and there may be congenital infections after birth such as hydrocephalus, meningitis and other signs of the infection. 2. Campylobacteriosis: It is also a common pet-related bacterial infectious disease, and dogs and cats are carriers and sources of infection. People who accidentally eat Campylobacter-infected water and food will suffer from generalized discomfort, malaise, chills, and so on. 3. Allergy: Pet dander is a major allergen, which can cause allergic rhinitis and allergic asthma. 4. Scratches and bites: Even if a healthy pet scratches and bites will not be infected with rabies and other diseases, the scratches and bites may cause wound infections. Pregnant pets should be more careful than usual, in order to ensure the safety of the situation before keeping pets.
