Pregnancy during a cold can definitely have an impact on the fetus. The early stage of pregnancy is the most critical period for the development of the fetus, and having a cold during this period can have a significant impact on the fetus. In particular, influenza virus can enter the fetus through the placental barrier, which may cause congenital heart disease, cleft lip, hydrocephalus, etc. Moreover, high fever and metabolic disorders can stimulate uterine contractions and cause miscarriage or premature delivery, while prolonged persistence of body temperature at high temperature may cause child malformation. Therefore, it is important to pay attention to the prevention and treatment of the disease, and never catch a cold during pregnancy, and do not get pregnant during a cold.
