Infections in early pregnancy can have a serious impact on the development of the unborn child, especially on the formation of the neural tube. The neural tube, from which the brain and spinal cord are formed, closes as early as the third or fourth week of pregnancy, when many women are not yet aware of their condition. Therefore, infections at this stage can significantly increase the risk of birth defects.
Different infections have different effects on the mother’s body and fetal development. Viral, bacterial, and parasitic diseases can disrupt metabolism, increase inflammation, and lead to insufficient nutrient supply to the fetus. Some infections can directly affect the cells of the embryo, disrupting the normal formation of tissues and organs. All of this increases the likelihood of spina bifida, anencephaly, and other neural tube defects.
Particular attention is paid to infections that are most common in women of reproductive age: rubella, cytomegalovirus, toxoplasmosis, and certain bacterial infections. If a pregnant woman encounters such diseases in the early stages, the risk of congenital disorders increases significantly. Even a mild infection can be a risk factor, especially if the mother’s body is weakened and does not receive enough vitamins, including folic acid, which protects the neural tube
Preventing infections before and during early pregnancy is extremely important. This includes practicing good personal hygiene, getting vaccinated before planning a pregnancy, avoiding contact with sick people, and managing chronic diseases that can weaken the immune system. It is also important to maintain a healthy lifestyle: proper nutrition, avoiding harmful habits, getting enough sleep, and moderate physical activity help the body better resist infections.
If you are planning a pregnancy, it is helpful to undergo a medical examination and discuss preventive measures with your doctor. Tests for antibodies to certain infections, vaccinations, and timely treatment of diseases help reduce risks to the fetus.
Understanding the importance of early protection against infections and paying close attention to your own health can reduce the risk of neural tube defects and other congenital disorders. A combination of measures — a healthy lifestyle, infection prevention, folic acid supplementation, and medical supervision — creates a safe environment for the baby’s development from the very first weeks of pregnancy.
