Mark, a new father, is concerned about passing on his current viral infection to his two- week-old baby. What should the occupational health nurse inform him regarding his - baby's risk of contracting his infection?
The baby has passive acquired immunity.
The baby has natural active immunity.
The baby's immunity is still underdeveloped and is at risk.
The baby has inherited natural immunity from the mother.
The Correct Answer is A
A. Passive immunity is typically acquired through maternal antibodies passed to the baby during pregnancy or breastfeeding, and will protect against viral infections.
B. Active immunity is developed by the body after exposure to an antigen. Since the baby hasn't been exposed to the virus yet, this option is not applicable.
C. Infants have an immature immune system. However, they rely on passive immunity from maternal antibodies and vaccinations to protect against infections.
D. Infants inherit passive acquired immunity from the mother and not natural immunity.
