Final answer:
The most common cause of skin lesions in school-age children is communicable diseases and bacterial infections, particularly eczema and acne caused by inflammation or clogging of hair follicles.
Step-by-step explanation:
The most common cause of skin lesions for school-age children is communicable diseases and bacterial infections. These conditions often result in rashes or lesions that might take the form of a pustule, ulcer, or vesicle.
Two common skin disorders in this age group are eczema and acne. Eczema is an inflammatory condition that can affect individuals of all ages. Acne is often seen in adolescents and involves the clogging of pores, which can lead to infection and inflammation. These skin disorders are exacerbated by the inflammation of hair follicles or by hair follicles becoming clogged with lipids, fatty acids, and dead skin cells, creating an environment where bacteria can thrive.
Asymptomatic health care workers can transmit bacteria such as MRSA to patients, potentially leading to skin infections or other health issues. It is important for caregivers and children alike to practice good hygiene to reduce the likelihood of such infections.
