The traveling caterpillar traveled 6,000 kilometers under the skin of a Russian woman. A tourist brought the parasite from the Maldives after walking barefoot on the beach. Four days before her flight, her toe began to itch—the supposed bite soon turned into a growing, twisting path. The medicine from the first aid kit did not help. Already in Moscow, the woman changed several doctors before a wandering caterpillar (migraine caterpillar) was discovered in a special institute. The patient is prescribed treatment, but the choice of medication complicates breastfeeding. The wound is gradually healing. The larvae can enter under the skin by contact with hot sand contaminated with animal feces. Moving under the skin, they cause itching, burning and inflammation. For such parasites, a person is a transit station.
