What is tungiasis?
Generally, tungiasis is a parasitic infection caused by sand fleas invading and parasitizing human skin. The detailed analysis is as follows:

Tungiasis is a parasitic disease caused by female sand fleas penetrating the human skin, commonly occurring in tropical regions with poor hygiene conditions. Female sand fleas often hide in damp sand or soil, and upon contact with the human body, they burrow into the skin and reside beneath it to lay eggs and reproduce. As the sand fleas move and their eggs hatch, localized skin reactions such as redness, swelling, itching, and pain may develop. In later stages, ulcers and secondary infections may form, and severe cases can lead to tissue necrosis and impaired limb function. The occurrence of this disease is closely associated with direct skin contact with contaminated environments; individuals who walk barefoot or wear unclean clothing are particularly susceptible to infection.
Prevention and care should focus on preventing exposure. In endemic areas, avoid walking barefoot and wear breathable, non-slip socks and shoes. Maintain clean and dry skin daily, change clothes frequently, and ensure thorough drying after washing. If signs of foreign body penetration into the skin are detected, promptly rinse the area with clean water and avoid scratching to prevent infection. Seek immediate medical attention upon developing clear symptoms and follow healthcare instructions for treatment. Additionally, improve environmental hygiene by regularly removing stagnant water and debris to reduce breeding grounds for sand fleas, thereby minimizing infection risks at the source.
