B76.9
Hookworm disease, unspecified
Clinical Classification Guidelines
Inclusion Terms
- Cutaneous larva migrans NOS
Medical Intelligence & Overview
Hookworm disease is a parasitic infection caused primarily by two species of hookworms, Ancylostoma duodenale and Necator americanus. While these parasites mainly inhabit the intestines, their larvae can penetrate the skin, leading to a condition known as cutaneous larva migrans. The term 'unspecified' in the diagnosis indicates that a specific hookworm species or detailed clinical features haven't been identified. This condition is common in tropical and subtropical regions and can affect individuals exposed to contaminated soil or sand.
Causes & Symptoms
Clinical Causes: Contact with contaminated soil or sand where hookworm larvae are present Walking barefoot or having skin contact with moist, contaminated ground Ingestion of contaminated food or water (less common) Poor sanitation and hygiene practices that allow larvae to thrive in the environment
Key Symptoms: Itchy, red skin lesions at the site of larva penetration Winding or linear tracks on the skin as larvae migrate underneath Localized swelling, soreness, or inflammation Possible secondary bacterial infection if the skin is scratched In rare cases, systemic symptoms such as fever, chills, or malaise if the infection penetrates deeper
Diagnostic & Treatment
Diagnosis Path: Diagnosis primarily relies on clinical examination, noting characteristic skin tracks and lesions. Medical history regarding exposure to contaminated environments aids in identification. In some cases, a skin biopsy or microscopic examination of skin samples can help detect larvae. Blood tests are generally not specific but can assess for eosinophilia, which suggests parasitic infection.
Treatment Protocols: Treatment typically involves antiparasitic medications such as albendazole or ivermectin to eradicate the larvae. Managing skin symptoms includes topical antipruritics and corticosteroids to reduce itching and inflammation. Preventative measures focus on avoiding contact with contaminated soil, wearing protective clothing, and improving sanitation standards. Secondary bacterial infections should be treated with appropriate antibiotics if they develop.
