Previous studies did not distinguish new incident infections, from past infections. Regardless of symptoms, we performed multiplex real-time polymerase chain reaction on pre- and post-travel stool samples of Dutch long-term travelers to the (sub)tropics. Serological screening for Schistosoma<\/jats:italic> spp. was only performed in travelers to sub-Saharan Africa. In total, 679 travelers were included in the study. The follow-up rate was 82% (556 of 679). Participants' median travel duration was 12 weeks. There was one incident infection with Strongyloides stercoralis<\/jats:italic>; there were none with Entamoeba histolytica<\/jats:italic>, 4 with Cryptosporidium<\/jats:italic> spp. (1%), and 22 with Giardia lamblia<\/jats:italic> (4%). Nine of 146 travelers (6%) seroconverted for Schistosoma<\/jats:italic> spp. Routine screening of stool samples for parasitic infection is not indicated for asymptomatic people, who travel to the (sub)tropics for up to 3 months. Screening for Schistosoma<\/jats:italic> spp. should be offered to travelers with fresh-water contact in endemic regions.<\/jats:p>","DOI":"10.4269\/ajtmh.13-0594","type":"journal-article","created":{"date-parts":[[2014,3,11]],"date-time":"2014-03-11T03:17:37Z","timestamp":1394507857000},"page":"835-839","source":"Crossref","is-referenced-by-count":29,"title":["Post-Travel Screening of Asymptomatic Long-Term Travelers to the Tropics for Intestinal Parasites Using Molecular Diagnostics"],"prefix":"10.4269","volume":"90","author":[{"given":"Darius","family":"Soonawala","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisette","family":"van Lieshout","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marion A.
