From the Guidelines

No, a mother with a herpes simplex virus (HSV) lesion on her breast should not safely breastfeed from the affected breast.

Breastfeeding Precautions

  • The American Academy of Pediatrics recommends against breastfeeding from the breast with an active herpes simplex lesion to prevent transmission of the virus to the infant 1.
  • However, the mother can still breastfeed from the unaffected breast, reducing the risk of transmission.
  • It is essential to follow proper precautions, such as covering the lesion and practicing good hygiene, to minimize the risk of transmission to the infant.
  • The decision to breastfeed from the unaffected breast should be made in consultation with a healthcare provider, taking into account the individual circumstances and the risk of transmission.

From the Research

Breastfeeding with Herpes Simplex Virus (HSV) Lesion on the Breast

  • A mother with a herpes simplex virus (HSV) lesion on her breast can safely breastfeed, but there are certain precautions to be taken 2.
  • According to a case report, a mother with severe HSV-1 infection on her breasts was able to maintain lactation and re-establish breastfeeding after recovery, with the support of a multidisciplinary team 3.
  • However, if there is a herpetic lesion on the nipple, breastfeeding is contraindicated 2.
  • The risk of transmission of HSV to the infant through breast milk is considered low, but the risk of post-natal transmission through contact with the lesion is higher 2.
  • A review of the literature suggests that HSV breast lesions can be acquired through sexual contact or from an infected infant, and that clinical signs for early diagnosis are important for proper management 4, 5.

Management of HSV Lesion on the Breast

  • The management of a mother with an HSV lesion on the breast requires a multidisciplinary approach, including lactation support and wound care 3.
  • Antiviral treatment, such as aciclovir, may be necessary to manage the infection 2.
  • The mother should be advised to express milk frequently to maintain milk production, and to take precautions to prevent transmission of the virus to the infant 3.
  • The decision to continue breastfeeding should be made on a case-by-case basis, taking into account the risk of transmission and the benefits of breastfeeding 2, 6.
