False, it is actually possible for infants to contract the virus from their mothers during childbirth.
The most common case of viruses getting passed on to a mother's child during birth is HIV. They can also contract Hepatitis B (not A), herpes, measles, and many other cases.
Childs and mothers share many things in common while the child is in childbirth, this question is specifically asking about the virus of HIV, and since the virus is passed through blood and through contact with sexual fluids, so the kid during birth can be in contact with contaminated blood and with vaginal fluids, so te kid can get HIV at child birth.
