Hookworm larvae, commonly found in contaminated sand or soil, can penetrate the skin and cause a condition known as cutaneous larva migrans.
Once inside the body, the larvae travel under the skin, causing intense itching, blisters, and a winding rash as they move through the tissue.
The couple was immediately prescribed antiparasitic medication and a topical treatment to alleviate the symptoms and prevent further spread of the infection.
Doctors also warned them that the infection could have been prevented if they had worn protective footwear while walking on the beach.
“Walking barefoot in areas with potential contamination can be incredibly risky,” said Dr. Laura Chen, an infectious disease specialist. “Hookworm larvae are microscopic, so you won’t see them — but they can still enter the body through the skin.”
