Pregnancy with a cold can have an effect on the fetus. In the early stages of pregnancy, since the fetal organs are not yet fully developed, bacteria and viruses can affect the development of fetal organs through the placenta after catching a cold, resulting in serious consequences such as congenital heart disease, hare lip, hydrocephalus, anencephaly or microcephaly. In late pregnancy, although the fetus is basically fully developed and the chances of the cold causing malformations or congenital defects to the fetus are reduced, the high fever and toxins from metabolic disorders caused by the cold can stimulate the uterus to contract, which can easily cause premature delivery and increase the mortality rate of newborns. When a pregnant woman has more serious symptoms of a cold with headache, sore throat and shortness of breath, it is recommended to identify as soon as possible whether the cold is wind-cold or wind-heat, and to use the right medicine under the guidance of a doctor. Pregnant women with colds that have symptoms of persistent high fever that does not go away or are caused by a cold virus infection can have a significant impact on the fetus.
