What statement indicates understanding of infection prevention in pregnancy?

The chosen statement demonstrates an understanding of infection prevention during pregnancy by recognizing the importance of timing in exposure to infectious diseases. When it states that it is acceptable to visit someone with chickenpox five days after the sores have crusted, it reflects the understanding that chickenpox is most contagious from about two days before the rash appears until the sores have fully crusted over. Since the individual is no longer contagious after this period, the risk of infection is significantly reduced.

This understanding is crucial for a pregnant individual because certain infections can pose risks to both the mother and the developing fetus. By adhering to this guideline about exposure timing, the person shows awareness of assessing risk while still maintaining social connections.

The other statements indicate misunderstandings or overly cautious approaches. Visiting anyone with an active infection raises inherent risks, avoiding all public places may not be practical and could lead to social isolation, and vaccination guidelines typically advise against receiving certain live vaccines during pregnancy, including the chickenpox vaccine.
