It is impossible for an infant to contract the hiv virus from their mother during childbirth

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.

Think it's rice because in many countries rice is the main food so it can be traditionally served all at once.
