Tungiasis: What It Is, How It Looks, and How to Deal With It

Tungiasis is a skin infection caused by the sand flea Tunga penetrans. The tiny flea burrows into the top layer of skin, usually on the feet, and starts to grow. It’s common in warm, sandy places where people walk barefoot.

First signs are a small, itchy bump that may look like a wart or a pimple. As the flea grows, the bump gets larger, turns white or yellow, and can feel painful when you press it. You might also see a dark spot in the center – that’s the flea’s rear opening.

How You Can Get Tungiasis

The flea lives in sandy soil, especially near beaches, farms, or dusty streets. When you walk without shoes, the flea can jump onto your skin. Children, farmers, and anyone who spends a lot of time outdoors are at higher risk.

Contaminated clothing or socks can also bring the flea into close contact with your skin. The infection spreads quickly in crowded living conditions where people share sandals or walk on the same ground.

Safe Ways to Treat the Infection

The quickest fix is to have a health professional remove the flea. They use a sterile needle or tweezers to pull the bug out without breaking it. If the flea breaks, it can cause more inflammation, so it’s best left to a pro.

If you can’t see a doctor right away, keep the area clean with soap and water. Apply a mild antiseptic ointment to stop infection. Avoid squeezing or digging at the bump – that can make things worse.

Over‑the‑counter pain relievers like ibuprofen can help with pain and swelling. In some cases, a doctor may prescribe antibiotics if there’s a secondary bacterial infection.

After removal, keep the wound covered with a clean bandage and change it daily. Watch for signs of infection such as increasing redness, pus, or fever, and seek medical help if they appear.

Prevention Tips You Can Use Today

The easiest way to avoid tungiasis is to wear shoes or sandals outdoors, especially on sandy or dusty ground. Closed‑toe shoes are best, but sturdy flip‑flops work if you’re at the beach.

Keep your feet clean and dry. After walking in sand, wash your feet thoroughly and dry them well. If you live in an area where tungiasis is common, treat your shoes with a flea‑repellent spray.

Regularly clean your home’s floor mats and replace old socks and shoes. For kids, check their feet daily for any new bumps, especially after playing outside.

If you travel to a region where tungiasis is known, pack a pair of lightweight, protective shoes and a small bottle of antiseptic cream. A quick check of your feet before bed can catch early signs.

Staying aware and taking simple steps—like wearing shoes and keeping skin clean—cuts the risk dramatically. If you do get a bump, get it checked fast to keep the infection from spreading.
