How to Prevent Newborn Cold Transmission from Mother?

Common Cold in Newborns?

Dear Doctor: I am about to give birth, but I have a slight cold.
I am very worried about transmitting the cold to my baby after birth.
How can I prevent my baby from getting infected with a cold? Is it serious if the baby catches a cold? A concerned mother.

Dr. Pei Rensheng reply Pediatrics

Dear Xiaofen,
Hello! The vast majority of colds do not have significant effects on the health of mothers and their fetuses.
Common cold viruses may slightly increase the risk of miscarriage, but they do not raise the rate of fetal abnormalities, especially in early pregnancy.
Regarding mild, transient fever during a cold, it generally does not harm the mother or fetus.
However, some studies have indicated that if a pregnant woman’s body temperature exceeds 38.9°C (102°F) for more than 24 hours during the early weeks of pregnancy (specifically during the neural tube development period), there may be an increased risk of neural tube defects (such as anencephaly) in the fetus.
It is important to emphasize that very few pregnant women allow their body temperature to rise this high and remain elevated for such a long time without taking any action.
As for the impact of the influenza virus, past statistical reports have shown that if a pregnant woman contracts influenza, it may lead to congenital anomalies (including neural tube defects, limb defects, and congenital heart disease), miscarriage, stillbirth, and low birth weight.
There is also a higher likelihood of developing blood cancers in childhood, as well as an increased risk of Parkinson's disease and schizophrenia in adulthood; however, the actual incidence of these abnormalities is low.
In terms of medication treatment, during early pregnancy (the so-called "organogenesis period"), obstetricians typically carefully assess the risks of medication use, avoiding category D and X drugs and opting for safer alternatives.
In the mid to late stages of pregnancy, the impact of cold medications on the fetus is even less significant.
Experts recommend that pregnant women receive the influenza vaccine as a proactive measure against influenza.
The influenza vaccine is safe, effective, and inexpensive, made from inactivated viruses (similar to vaccines for tetanus, hepatitis A, and B), making it suitable for pregnant women.
The American College of Obstetricians and Gynecologists supports the recommendations of the Centers for Disease Control and Prevention, urging women who are planning to become pregnant, as well as those in their second and third trimesters, and pregnant women with chronic pulmonary or cardiac conditions, to receive the influenza vaccine during the flu season (from October to May each year).
The World Health Organization also considers it safe for women to receive the influenza vaccine during pregnancy, and there is currently no evidence to suggest that vaccination adversely affects the fetus.
Wishing you health and happiness!
Sincerely,
Dr.

Director of Pediatrics, Taoyuan Hospital, Department of Health

More Info

As a soon-to-be mother, it's completely normal to be concerned about the health of your newborn, especially when you're experiencing symptoms of a cold. Here are several strategies to help prevent the transmission of a cold from you to your newborn, along with some insights into the implications of a cold in infants.

Preventive Measures
1. Practice Good Hygiene: The most effective way to prevent the spread of germs is through proper hygiene. Wash your hands frequently with soap and water, especially before handling your baby. If soap and water are not available, use an alcohol-based hand sanitizer.

2. Avoid Close Contact: Try to minimize close contact with your newborn, especially during the first few weeks when their immune system is still developing. If possible, have someone else care for the baby while you are symptomatic.

3. Wear a Mask: If you must be close to your newborn while you have cold symptoms, consider wearing a mask. This can help reduce the risk of airborne transmission of viruses.

4. Limit Coughing and Sneezing Near the Baby: If you feel the urge to cough or sneeze, do so into a tissue or your elbow, and step away from your baby. Dispose of tissues immediately and wash your hands afterward.

5. Keep the Environment Clean: Regularly disinfect surfaces that you frequently touch, such as doorknobs, light switches, and baby items like toys and changing tables.

6. Maintain a Healthy Environment: Ensure that your living space is well-ventilated and that you are not exposing your newborn to smoke or other irritants that could compromise their respiratory health.

7. Stay Hydrated and Rested: Taking care of your own health is crucial. Stay hydrated, eat nutritious foods, and get plenty of rest to help your immune system fight off the cold.

Implications of a Cold in Newborns
If your newborn does happen to catch a cold, it’s important to monitor their symptoms closely. Infants are particularly vulnerable, and even a mild cold can lead to complications. Here are some signs to watch for:
- Fever: A rectal temperature of 100.4°F (38°C) or higher is considered a fever in infants. If your baby has a fever, contact your pediatrician immediately.

- Difficulty Breathing: If your baby is having trouble breathing, is wheezing, or is breathing faster than normal, seek medical attention.

- Poor Feeding: If your baby is not feeding well or seems lethargic, it may be a sign that they are not feeling well.

- Persistent Cough: A cough that lasts more than a few days or worsens should be evaluated by a healthcare provider.

Conclusion
While it’s understandable to be worried about transmitting a cold to your newborn, taking proactive steps can significantly reduce the risk. Remember that newborns have immature immune systems, so any illness can be more serious for them than for adults. If you have any concerns about your health or your baby’s health, don’t hesitate to reach out to your healthcare provider for personalized advice and support. Your well-being and that of your baby are paramount, and being informed is the best way to ensure a healthy start for your little one.
