Is a 38°C fever during the second month of pregnancy harmful to the fetus?

Generally speaking, whether a fever of 38°C at two months of pregnancy affects the fetus depends on a comprehensive assessment of factors such as the cause of the fever, its duration, and whether timely intervention was provided. The specific analysis is as follows:

If the fever is caused by a common cold, lasts less than 24 hours, is promptly managed with physical cooling or safe medications under medical guidance, and is not accompanied by symptoms such as convulsions or severe headache, the impact on the fetus is usually minimal. In such cases, the body's stress response is mild, and once the temperature is quickly controlled, embryonic development is typically not significantly disrupted. Regular prenatal checkups are sufficient for ongoing monitoring.

If the fever is triggered by viral infections such as influenza or rubella, persists for more than 48 hours without effective control, or is accompanied by high fever-induced seizures or severe signs of infection, it may have adverse effects on the fetus. The second month of pregnancy is a critical period for organ differentiation, and prolonged high temperature or viral invasion may interfere with embryonic development and increase the risk of congenital abnormalities. Immediate medical evaluation to determine the cause and appropriate intervention is necessary.

In daily care, drink plenty of warm water to promote metabolism, and use lukewarm water to wipe areas such as the forehead and armpits to assist in cooling. Maintain a light and easily digestible diet, and consume more fresh fruits and vegetables to supplement vitamins. Ensure adequate rest and avoid fatigue; keep indoor areas well-ventilated. Avoid crowded places and take precautions to stay warm and prevent colds. After developing a fever, promptly record changes in body temperature and symptoms, follow medical advice for prenatal checkups, and seek immediate medical attention if any abnormalities occur.
