What is creeping eruption commonly caused by?

Creeping eruption, also known as cutaneous larva migrans, is primarily caused by the larvae of hookworms, particularly those found in animal feces. When contaminated soil or sand comes into contact with the skin, the larvae can penetrate the epidermis and start to migrate, causing an intensely itchy, serpiginous rash. This condition is most commonly associated with barefoot exposure on contaminated beaches or areas where animals have defecated.

The option related to infected larvae penetrating the skin accurately describes this parasitic condition and its mechanism. Understanding the life cycle of hookworms and their propensity to infect humans when certain conditions are met is crucial for recognizing how creeping eruption occurs. The physical characteristics of the rash and the specific source of infection align perfectly with this explanation.

Other potential causes, such as fungal infections or pesticide exposure, do not align with the biological process that leads to creeping eruption. Fungal infections are typically associated with different symptoms and transmission routes, while pesticide exposure would present a different set of symptoms unrelated to larval penetration. Contaminated water exposure can lead to various illnesses, but it is not a typical cause of creeping eruption. Thus, the understanding of the specific causative agent in this case is essential for properly identifying and addressing the
