Can You Pass HPV Through Breast Milk?

Human Papillomavirus (HPV) is a common viral infection. New mothers often wonder if HPV can be passed to their infant through breast milk. This article explores HPV transmission and the safety of breastfeeding for mothers with the virus.

How HPV is Transmitted

HPV primarily spreads through direct skin-to-skin contact, most commonly during sexual activity. This can occur even without visible symptoms. Many sexually active individuals will contract HPV at some point.

HPV can also transmit from a mother to her baby during vaginal childbirth. While less common than sexual transmission, this is a recognized way for infants to acquire the virus. HPV can persist for years, but in most cases, the immune system clears the infection.

Is HPV Passed Through Breast Milk?

Current scientific consensus indicates that HPV is not typically transmitted through breast milk. While HPV DNA might occasionally be detected in breast milk samples, its presence does not necessarily mean it can cause infectious transmission to the infant.

Studies analyzing breast milk have sometimes found HPV DNA, including high-risk strains, but have not established a causal link between its presence in milk and the development of HPV infection in breastfed babies. For instance, one study identified high-risk HPV in a small percentage of milk samples, yet found no evidence of the virus in the children who consumed that milk. This suggests that even if viral DNA is present, the risk of a baby acquiring HPV from breast milk is extremely low.

HPV and Infant Health

While transmission through breast milk is highly unlikely, infants can acquire HPV through other means, primarily during passage through an infected birth canal. In rare cases, this perinatal transmission can lead to a condition known as Recurrent Respiratory Papillomatosis (RRP). RRP involves the growth of non-cancerous, wart-like tumors, most often in the larynx or voice box, which can affect a child’s voice and breathing.

RRP is a rare condition, with estimates ranging from 1 to 4 cases per 100,000 births. The types of HPV most commonly associated with RRP are HPV 6 and 11. Although serious, many infants who acquire HPV during birth may not develop symptoms, as their immune systems often clear the virus.

Breastfeeding Guidelines for Mothers with HPV

Based on current scientific understanding, breastfeeding is considered safe and recommended for mothers with HPV. Major health organizations do not advise against breastfeeding due to an HPV diagnosis. The numerous health benefits that breastfeeding provides to both mother and infant outweigh the minimal, if any, risk of HPV transmission through milk.

Mothers with HPV who have concerns about breastfeeding should discuss their individual situation with a healthcare provider. Medical professionals can offer personalized advice and reassurance regarding the safety of breastfeeding. The HPV vaccine is also safe for breastfeeding mothers and does not pose a risk to the nursing infant.
