A myiasis by <jats:italic>C. hominivorax<\/jats:italic> in a 71-year-old man with a 4-month history of foot hyperkeratosis and interdigital ulcers is reported. The myiasis was detected before sampling for bacterial culture. Approximately 160 first- and second-instar larvae were recovered and identified as <jats:italic>C. hominivorax<\/jats:italic>. Morphological identification was based mainly on characteristics of the cephalopharyngeal skeleton, spiracles, and pigmented dorsal tracheal trunks. Sequencing of a cytochrome <jats:italic>c<\/jats:italic> oxidase subunit I gene fragment confirmed the identity. The ulcers healed after extraction of the larvae and ciprofloxacin treatment of a concurrent <jats:italic>Staphylococcus aureus<\/jats:italic> and <jats:italic>Pseudomonas aeruginosa<\/jats:italic> infection. Given the reintroduction of <jats:italic>C. hominivorax<\/jats:italic> in Costa Rica and the risk of northward expansion, this report highlights its impact on public health and calls for awareness among clinicians and healthcare practitioners.<\/jats:p>","DOI":"10.4269\/ajtmh.24-0342","type":"journal-article","created":{"date-parts":[[2024,9,18]],"date-time":"2024-09-18T13:32:13Z","timestamp":1726666333000},"page":"1020-1023","source":"Crossref","is-referenced-by-count":14,"title":["Case Report: Re-Emergence of Cochliomyia hominivorax in Costa Rica: Report of a Human Myiasis Case 23 Years after Elimination"],"prefix":"10.4269","volume":"111","author":[{"given":"Daniela P.","family":"Venegas-Montero","sequence":"first","affiliation":[{"name":"Laboratorio Cl\u00ednico, Hospital Juana Pirola, Caja Costarricense de Seguro Social, Puntarenas, Costa Rica;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda J.","family":"Alfaro-Vellanero","sequence":"additional","affiliation":[{"name":"Laboratorio Cl\u00ednico, Hospital Juana Pirola, Caja Costarricense de Seguro Social, Puntarenas, Costa Rica;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diana","family":"Rojas-Araya","sequence":"additional","affiliation":[{"name":"Laboratorio de Investigaci\u00f3n en Vectores, Centro de Investigaci\u00f3n en Enfermedades Tropicales, Universidad de Costa Rica, San Jose, Costa Rica;"},{"name":"Secci\u00f3n de Entomolog\u00eda M\u00e9dica, Facultad de Microbiolog\u00eda, Universidad de Costa Rica, San Jose, Costa Rica"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00d3lger","family":"Calder\u00f3n-Arguedas","sequence":"additional","affiliation":[{"name":"Laboratorio de Investigaci\u00f3n en Vectores, Centro de Investigaci\u00f3n en Enfermedades Tropicales, Universidad de Costa Rica, San Jose, Costa Rica;"},{"name":"Secci\u00f3n de Entomolog\u00eda M\u00e9dica, Facultad de Microbiolog\u00eda, Universidad de Costa Rica, San Jose, Costa Rica"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cinthya M.","family":"Vargas-Castro","sequence":"additional","affiliation":[{"name":"Laboratorio Cl\u00ednico, Hospital Juana Pirola, Caja Costarricense de Seguro Social, Puntarenas, Costa Rica;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9s","family":"Baldioceda-Villarreal","sequence":"additional","affiliation":[{"name":"Laboratorio de Investigaci\u00f3n en Vectores, Centro de Investigaci\u00f3n en Enfermedades Tropicales, Universidad de Costa Rica, San Jose, Costa Rica;"},{"name":"Secci\u00f3n de Entomolog\u00eda M\u00e9dica, Facultad de Microbiolog\u00eda, Universidad de Costa Rica, San Jose, Costa Rica"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis Enrique","family":"Chaves-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Laboratorio de Investigaci\u00f3n en Vectores, Centro de Investigaci\u00f3n en Enfermedades Tropicales, Universidad de Costa Rica, San Jose, Costa Rica;"},{"name":"Secci\u00f3n de Entomolog\u00eda M\u00e9dica, Facultad de Microbiolog\u00eda, Universidad de Costa Rica, San Jose, Costa Rica"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacqueline","family":"Camacho-Leandro","sequence":"additional","affiliation":[{"name":"Laboratorio de Investigaci\u00f3n en Vectores, Centro de Investigaci\u00f3n en Enfermedades Tropicales, Universidad de Costa Rica, San Jose, Costa Rica;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adriana","family":"Troyo","sequence":"additional","affiliation":[{"name":"Laboratorio de Investigaci\u00f3n en Vectores, Centro de Investigaci\u00f3n en Enfermedades Tropicales, Universidad de Costa Rica, San Jose, Costa Rica;"},{"name":"Secci\u00f3n de Entomolog\u00eda M\u00e9dica, Facultad de Microbiolog\u00eda, Universidad de Costa Rica, San Jose, Costa Rica"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2795","reference":[{"key":"b1","series-title":"Medical and Veterinary Entomology","first-page":"383","article-title":"Myiasis (Muscoidea, Oestroidea)","author":"Scholl","year":"2019"},{"key":"b2","series-title":"Ann N Y Acad Sci","first-page":"186","article-title":"Screwworm eradication in the Americas","volume":"916","author":"Wyss","year":"2000"},{"key":"b3","series-title":"Bolet\u00edn Epidemiol\u00f3gico Extraordinario Gusano Barrenador","year":"2024"},{"key":"b4","series-title":"Rev Med Hosp Nac Ni\u00f1os (Costa Rica)","first-page":"95","article-title":"Las miasis en nuestros ni\u00f1os, estudio de 35 casos","volume":"6","author":"Morales","year":"1971"},{"key":"b5","series-title":"Rev Med Costa Rica","first-page":"5","article-title":"Miasis \u00f3tica","volume":"478","author":"Niehaus","year":"1982"},{"key":"b6","series-title":"Rev Costarric Cienc Med","first-page":"61","article-title":"Miasis oral por Cochliomyia hominivorax (Diptera;
