Can HPV Transfer to a Baby During Pregnancy or Birth?

Human Papillomavirus (HPV) is a common viral infection that often transmits through skin-to-skin contact, typically during sexual activity. While such transmission is common among adults, the possibility of HPV transferring from a pregnant individual to their baby is a question many consider. Though uncommon, HPV can transmit from a mother to her baby. The risk of such an event remains low.

How HPV Transfers to Infants

HPV can transmit to an infant primarily during vaginal birth. This occurs when the baby passes through the birth canal, which may contain HPV lesions or infected cells.
In extremely rare instances, HPV transmission can occur before birth, while the baby is still in the uterus. This is known as in-utero or transplacental transmission. Such cases are exceptional and not considered a common pathway for the virus to pass from mother to child.

Impact of HPV on Infants

If HPV transmits to an infant, the most significant, though rare, complication is Recurrent Respiratory Papillomatosis (RRP). RRP involves the growth of benign, wart-like tumors, called papillomas, within the respiratory tract, most commonly in the larynx. These growths can lead to symptoms such as hoarseness, a chronic cough, and breathing difficulties.

Treatment for RRP typically involves surgical removal of the papillomas to alleviate symptoms and maintain an open airway. Multiple surgeries may be necessary over time as the growths can recur. Other rare manifestations in infants can include the development of genital warts, which often resolve without specific intervention.

Navigating HPV During Pregnancy

Pregnant individuals with HPV should maintain open communication with their healthcare providers. Regular cervical screenings, such as Pap tests, continue during pregnancy to monitor any changes in cervical cells. These screenings help guide medical decisions.

A Cesarean section (C-section) is generally not recommended solely because of an HPV diagnosis. The risk of transmission during vaginal birth is low, and a C-section carries surgical risks. A C-section might be considered only in specific situations, such as when large genital warts are present and physically obstruct the birth canal, potentially hindering delivery.

Minimizing Transmission Risk

One of the most effective long-term strategies for preventing HPV infection, and subsequently minimizing the potential for transmission to an infant, is vaccination. The HPV vaccine is recommended for eligible individuals well before pregnancy. This vaccine protects against the types of HPV most commonly associated with cervical cancer and RRP.

Maintaining regular health check-ups and practicing safe sexual behaviors are also important general health measures that can reduce the risk of acquiring HPV. For individuals already pregnant, the primary focus is on appropriate medical management, as discussed previously. The overall risk of HPV transmission to the baby remains low.
