We describe an outbreak of cutaneous larva migrans (CLM) in a group of 140 holidaymakers to a resort in Barbados and the index case. methods A two-page questionnaire was mailed to holidaymakers and 90% responded. results 25.4% of respondents developed a rash consistent with CLM. Risk factors for developing the illness were younger age and less frequent use of protective footwear while walking to the beach. Patients had difficulty in obtaining a correct diagnosis during their initial medical consultation and in obtaining medication from pharmacies. Efficacious treatments were oral and topical thiabendazole. conclusions CLM can occur in a large proportion of people exposed to contaminated soil or sand. Protective footwear is effective in reducing infection. Thiabendazole is an efficacious treatment.
