Bottle-feeding can prevent transmission of HTLV-I from mothers to their babies
1Department of Obstetrics and Gynaecology, Nara Medical University, Japan.
Breast-feeding is a major factor in the vertical transmission of human T-lymphotropic virus type I (HTLV-I). We studied whether such transmission may be prevented by bottle-feeding. HTLV-I infection was detected by both HTLV-I antigen and antibody tests. Thirty bottle-fed babies were examined 24 months after birth; only one was found to be HTLV-I antigen-positive. This infection rate was lower than that for breast-fed babies in whom HTLV-I antigen was detected in 24 of the 31 24-month-old babies born to HTLV-I positive mothers in a previous study. These results suggest that most vertical transmission of HTLV-I is attributable to breast-feeding and can be prevented by bottle-feeding.
