Here, we present updated information on the prevalence of these parasites in the Lao People's Democratic Republic (Lao PDR) in 2012, arising from the annual national helminthiasis survey. Fecal specimens were collected from 8,610 inhabitants of 12 provinces and one municipality (Bokeo, Houaphan, Luang Namtha, Luang Prabang, Oudomxay, and Phongsaly Provinces from northern Lao PDR; Bolikhamxay and Xieng Khouang Provinces and Vientiane Municipality from the central part of the country; and Attapeu, Champasak, Saravan, and Sekong Provinces from southern Lao PDR). The overall prevalence of three major STHs, <jats:italic>Ascaris lumbricoides<\/jats:italic>, <jats:italic>Trichuris trichiura<\/jats:italic>, and hookworms (<jats:italic>Necator americanus<\/jats:italic> and <jats:italic>Ancylostoma duodenale<\/jats:italic>) were 11.6%, 8.5%, and 25.0%, respectively. Prevalence of <jats:italic>Schistosoma mekongi<\/jats:italic> infection was 0.1%, and of miscellaneous trematodiases (including opisthorchiasis) was 14.0%. Clearly, the nationwide parasite control project is still necessary to reduce morbidity caused by helminthic diseases.<\/jats:p>","DOI":"10.4269\/ajtmh.13-0636","type":"journal-article","created":{"date-parts":[[2014,2,11]],"date-time":"2014-02-11T01:41:38Z","timestamp":1392082898000},"page":"667-669","source":"Crossref","is-referenced-by-count":21,"title":["Current
