Name one common complication of chickenpox.

Bacterial skin infections are a common complication of chickenpox, primarily because the itchy blisters that develop during the illness can become a site for bacteria to enter the skin, especially if they are scratched. When the skin is broken, it can lead to secondary infections, which may result in conditions such as cellulitis or impetigo. This is particularly a concern in children who might be more likely to scratch the itchy lesions, enabling bacteria to penetrate the skin barrier.

Other options, such as asthma, kidney failure, and osteoporosis, are not recognized as common complications directly associated with chickenpox. Asthma is a chronic respiratory condition that can be triggered in individuals with respiratory infections or allergies but is not a direct complication of chickenpox itself. Kidney failure and osteoporosis are not linked as complications arising from the chickenpox virus. Understanding these distinctions helps to clarify why bacterial skin infections represent a tangible and frequent complication following chickenpox.
