Cutaneous larva migrans

Cutaneous Larva Migrans

Cutaneous larva migrans (CLM) is a type of infection caused by a parasitic roundworm. It is also known as creeping eruption and has a unique pattern of skin lesions. These lesions are usually linear and become more pronounced when the infected individual scratches the affected area.

The parasite that causes CLM is found in warmer climates, such as those found in the Caribbean, Mexico, and some parts of the United States. It is primarily contracted when the sticky, hook like larvae of the roundworm come in contact with human skin. This often happens when people come in contact with soil, sand, or other contaminated areas.

The early stages of CLM typically consist of an intensely itchy reddish-brown rash. It is typically characterized by a curved, wriggling, red line made up of raised bumps or blisters. In the early stages, the bumps or blisters may contain larvae or eggs. As the infection progresses, the bumps or blisters may become filled with pus. In some cases, a blister may break and ooze a yellowish fluid that contains dead larvae.

Common symptoms of CLM include intense itching, swelling, and redness of the skin. Some people may also experience fever, headache, nausea, or joint pain.

Treatment for CLM usually involves medication such as an anti-parasitic cream or oral medication. It is important to take medication as prescribed by a doctor to ensure that the infection is completely cleared. In cases where the infection persists or recurs, more aggressive treatment may be necessary.

Preventing CLM is the best way to avoid this infection. Wearing plastic sandals when walking on soil or sand can help reduce the risk of infection. It is also important to thoroughly wash all fruits and vegetables before consumption, as these can also contain roundworm larvae or eggs. Wearing long pants and long-sleeved shirts when outdoors can also help protect against infection.

Preventive Measures

  • Wear plastic sandals when walking on soil or sand.
  • Thoroughly wash all fruits and vegetables before consumption.
  • Wear long pants and long-sleeved shirts when outdoors.
  • Avoid contact with contaminated soil or sand.
  • Wash hands frequently with soap and water.
