Final answer:
Option A. Family members of an infected individual should indeed be treated for scabies to prevent the spread of the condition, as scabies is highly contagious.
Step-by-step explanation:
When one family member is infected with scabies, it is highly likely that other family members may also become infected. Scabies is highly contagious and can spread through close physical contact, such as sharing bedding or clothing. Therefore, it is important to treat all family members to prevent the spread of scabies.
Scabies is a highly contagious skin condition caused by a tiny mite called Sarcoptes scabiei. Due to its contagious nature, it is recommended that not only the infected individual but also close contacts, including family members, receive treatment. This approach is taken even if family members do not show symptoms, as it can take up to six weeks for symptoms to appear after initial infestation, and during this time, those infected can still spread scabies.
