Minimal risk for breastfeeding and infant.
The human papillomavirus (HPV) is one of the most frequent found in adults, with more than 200 different types that, depending on the type, can cause cutaneous warts (types 1, 2, 3, 4, 7, 22 ...), anogenital warts (types 6, 11, 42 ...), laryngeal papillomatosis (types 6, 11) or genital cancer (types 16, 18, 31, 45 ...).
Transmission is via direct contact of skin and mucous membranes. Contagion may be due to sexual transmission, during childbirth or simply due to normal cohabitation, with no blood transmission (Gavillon 2010). HPV DNA is detected in up to 21% of pharyngeal secretions and up to 15% of genital samples of children under 3 years of age (Rintala 2005).
HPV DNA has been found in 1% of colostrum samples (Teixeira 2015), in 10% of breastmilk samples in the first week and in 30% of milk samples at 6 months, persisting in 6% of breastfeeding mothers (Louvanto 2017), without there being (oral) contagion in breastfed infants (Louvanto 2017).
DNA from high-risk oncogenic HPV strains was detected in 2 out of 80 breastmilk samples (2.5%), with negative detection in the cervix of these two mothers and in the oral cavity of their two infants (Yoshida 2011). Other authors did not detect HPV strains of high oncogenic risk in any milk sample (Mammas 2011 and 2010).
There are no studies documenting mother-to-child transmission of HPV through breastmilk or nipple lesions, so breastfeeding is considered compatible with any type of maternal HPV infection, including nipple lesions (Lawrence 2016 , Mammas 2010, Gavillon 2010).
For the purposes of processing milk donated to a milk bank, Holder pasteurization is known to inactivate both high risk oncogenic and low risk HPVs (Donalisio 2104).
