No new focus was found along the Colombia-Ecuador border. In the known focus, communities along the upper Micay River and its tributaries were surveyed; 655 adults underwent physical examinations and skin biopsies. Infected individuals were found almost exclusively in the community of Naiciona, where prevalence of infection was 40% (36 of 91). Polymerase chain reaction detection of onchocercal DNA in skin snips correlated with the skin-snip biopsy results. The prevalence of punctate keratitis, the only ocular manifestation found, was 33%. A rapid entomologic assessment demonstrated Simulium exiguum infected with Onchocerca volvulus. This is the first finding in Colombia of naturally infected black flies and confirms S. exiguum as a vector species. These data will be used for implementing a control program using periodic ivermectin distribution.<\/jats:p>","DOI":"10.4269\/ajtmh.1998.58.594","type":"journal-article","created":{"date-parts":[[2017,5,10]],"date-time":"2017-05-10T17:49:02Z","timestamp":1494438542000},"page":"594-598","source":"Crossref","is-referenced-by-count":12,"title":["Current status of onchocerciasis in Colombia."],"prefix":"10.4269","volume":"58","author":[{"given":"A","family":"Corredor","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R S","family":"Nicholls","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S","family":"Duque","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P","family":"Munoz de Hoyos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C A","family":"Alvarez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R H","family":"Guderian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H H","family":"Lopez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G I","family":"Palma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2795","container-title":["The American journal of tropical medicine and hygiene"],"original-title":[],"link":[{"URL":"https:\/\/www.ajtmh.org\/view\/journals\/tpmd\/58\/5\/article-p594.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.ajtmh.org\/downloadpdf\/journals\/tpmd\/58\/5\/article-p594.xml","content-type":"text\/html","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/www.ajtmh.org\/downloadpdf\/journals\/tpmd\/58\/5\/article-p594.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,9,4]],"date-time":"2024-09-04T12:00:15Z","timestamp":1725451215000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ajtmh.org\/view\/journals\/tpmd\/58\/5\/article-p594.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1998,5]]},"references-count":0,"journal-issue":{"issue":"5"},"URL":"https:\/\/doi.org\/10.4269\/ajtmh.1998.58.594","relation":{},"ISSN":["0002-9637"],"issn-type":[{"value":"0002-9637","type":"print"}],"subject":[],"published":{"date-parts":[[1998,5]]}}}
