Can chickenpox develop on the soles of the feet?

In general, chickenpox can develop on the soles of the feet, although it is relatively uncommon and typically considered an atypical location.

The skin on the soles of the feet is thick and usually protected by shoes, reducing the chance of direct viral contact infection. However, when patients scratch due to itching or other causes leading to indirect viral contact with the soles, infection may occur. This is more commonly seen in children, who spend less time wearing shoes and therefore have more opportunities for their soles to be exposed, increasing the likelihood of chickenpox developing on the feet.

Chickenpox rashes initially appear as light red macules, which then progress to papules and ultimately form fluid-filled vesicles. If chickenpox develops on the soles of the feet, the treatment principles are the same as for other body areas, primarily involving symptomatic management such as maintaining local cleanliness and dryness and avoiding scratching to prevent secondary infection.

It should be noted that the progression and symptom presentation of chickenpox vary among individuals. Therefore, even if a rash resembling chickenpox appears on the soles, a comprehensive evaluation combining other clinical information is necessary. Additionally, treatment for chickenpox should involve early administration of antiviral medications and following medical guidance for care and observation to alleviate symptoms, shorten the duration of illness, and prevent complications.
