Can I breastfeed if I have HTLV?
HTLV, or human T-cell leukemia virus, causes serious disease in some people, including blood cancer and chronic lung disease. It can be transmitted from mother to child during pregnancy or breastfeeding. The transmission rate from mother to child ranges from 4% to 30%, with most of these infections caused by breastfeeding. There is no treatment or vaccine for HTLV. Mothers who are HTLV-positive balance the risk of infection and disease with HTLV and the risks of not breastfeeding.
