Explanation:
Option (b) is correct i.e. pediculosis, contagious disease creates a primary skin lesion that is a pinpointed macule, papule, or wheal with hemorrhagic puncture site.
Most infections of head lice i.e. pediculosis are symptomless. When symptoms are present, there may be irritation, a tickling sensation as though something is moving in the hair, and itching due to an allergic reaction to louse saliva. One potential source of problems is secondary bacterial infection. The pathogens that cause Bartonella quintana, Rickettsia prowazekii, and Borrelia recurrentis body lice are a vector for (louse-borne relapsing fever). The most common way that head lice are transmitted is through contact with an infected person (i.e., head-to-head contact). During play (sports, playgrounds, summer camp, and sleepovers), at home, school, and in the community, there is frequently contact. Less frequently, it is possible for flies to transmit head lice (more common with body lice). Transmission can also occur if you use infected combs, brushes, towels, or if you lie on a bed, couch, pillow, carpet, or stuffed animal that has recently come into contact with an infected person.
