• during delivery

Reasoning:

Sexually transmitted infections are primarily passed through unprotected sexual encounters that involve fluid transfer from genital regions. These infections may also spread via blood and can be transmitted from mother to child at birth.

Using condoms consistently is the best way to lower the likelihood of STD transmission, particularly concerning HIV. Additionally, infection can occur through transfusions of tainted blood, or by sharing needles, especially among drug users. It's important to note that untreated infected mothers can transmit diseases like AIDS and syphilis to their infants during pregnancy and delivery, and in the case of AIDS, this also includes breastfeeding.
