During pregnancy, if a cold occurs, it should be analyzed based on the duration and type of the cold. Colds are generally categorized into common colds and influenza. Common colds are self-limiting, and typically heal on their own within 7 to 14 days without the need for medication.

Influenza can be accompanied by high fever, and severe cases can lead to serious complications such as pneumonia, thus requiring early detection and treatment. If the cold occurs within two weeks after ovulation and does not lead to miscarriage, the pregnancy can usually continue, and there will generally be no long-term impact on fetal development. However, if a cold occurs between the first to third month of pregnancy, during the period of fetal organ differentiation, it might lead to abnormal fetal development. Additional examinations would be necessary during the mid-term of the pregnancy. Colds that occur after the third month of pregnancy typically have a minor impact on the fetus, and usually do not require special treatment.
