Can Viruses Be Passed Through Breast Milk?
The question of whether viruses can be transmitted through breast milk is a complex one, with implications for maternal and infant health. While some viruses are known to be passed through breast milk, the specifics can vary significantly depending on the virus in question.
Transmission of Certain Viruses
Research indicates that certain infectious diseases can indeed be transmitted through breast milk. For instance, viruses such as HIV and HTLV (Human T-lymphotropic virus) are well-documented to pass from mother to child via breastfeeding. This transmission can pose serious health risks to infants, leading to recommendations against breastfeeding in cases where the mother is known to be infected with these viruses.
COVID-19 and Breast Milk
The situation with COVID-19, caused by the SARS-CoV-2 virus, has raised particular concerns among new mothers. Current research has not definitively established whether the virus can be reliably detected in breast milk or if it poses a risk of infection to infants. Experts have noted that while some studies have found traces of the virus in breast milk, the evidence is not conclusive enough to confirm that breastfeeding poses a significant risk of transmitting COVID-19 to infants. The consensus among health professionals is that the benefits of breastfeeding, including the transfer of antibodies and other protective factors, generally outweigh the potential risks associated with COVID-19.
Other Viruses and Infections
Beyond HIV and COVID-19, there are other infections that can be transmitted through breast milk. For example, certain bacterial infections and viruses like cytomegalovirus (CMV) can also be passed to infants during breastfeeding. This highlights the importance of screening and monitoring maternal health, particularly for infections that could affect breastfeeding practices.
The Role of Breast Milk in Infant Immunity
Interestingly, breast milk is not just a potential vector for viruses; it also plays a crucial role in protecting infants from infections. Breast milk contains antibodies and other immune factors that help to educate and strengthen the infant’s immune system. This phenomenon has been described as the mother educating her baby on how to best survive in their environment.
Conclusion
In summary, while some viruses can be transmitted through breast milk, the risk varies by virus and individual circumstances. For most mothers, the benefits of breastfeeding—such as providing essential nutrients and immune protection—are significant. However, in cases of specific infections, particularly those known to be transmitted through breast milk, careful consideration and medical guidance are essential to ensure the health and safety of both mother and child.

Can I pass the flu to my baby through breastfeeding?

Can you pass on illness through breast milk?

Are breastfed babies less likely to get RSV?

Infants receiving (exclusive or partial) maternal milk had lower risk of RSV bronchiolitis. Partial breastfeeding reduces risk of hospitalisation.

Can breastmilk transfer viruses?

Infectious organisms can reach the breast milk either by secretion in the fluid or cellular components of breast milk or by contamination of the milk at the time of or after expression. A reasonable mechanism of infection via breast milk should be evident and proved through either animal or human studies.
