Is upper respiratory tract infection in pregnant women harmful to the fetus?

The impact of upper respiratory tract infection in pregnant women on the fetus depends on the severity of the condition. Generally, if the symptoms are mild and there is no fever or only a low-grade fever, the impact on the fetus is minimal, and no special treatment is required; however, close monitoring of the condition is necessary. If the symptoms are severe, especially when accompanied by high fever (body temperature exceeding 38°C), there may be adverse effects on the fetus, such as fetal malformations, abnormal neural tube development, and congenital heart disease. In addition, improper use of medications during treatment by the pregnant woman may also have unfavorable effects on the fetus. Therefore, pregnant women with upper respiratory tract infection should seek medical attention promptly and follow medical advice for treatment, avoiding self-medication. At the same time, pregnant women should strengthen their constitution and enhance immunity to prevent the occurrence of upper respiratory tract infections.
