The aim of this study was to determine the prevalence of <jats:italic>S. stercoralis<\/jats:italic> and other intestinal parasites and identify the risk factors for infection with <jats:italic>S. stercoralis<\/jats:italic> in a rural area of Angola. A cross-sectional study was conducted in school-age children (SAC) in Cubal, Angola. A questionnaire collecting clinical and epidemiological variables was used, and two stool samples were collected. A concentration technique (Ritchie) and a technique for detection of larvae migration (Baermann) were performed. Of 230 SAC, 56.1% were female and the mean age was 9.3 years (SD 2.45). Severe malnutrition, according to body mass index (BMI)-for-age, was observed in 20.4% of the SAC, and anemia was found in 59.6%. <jats:italic>Strongyloides stercoralis<\/jats:italic> was observed in 28 of the 230 (12.8%) SAC. Eggs of other helminths were observed in 51 (22.2%) students: <jats:italic>Hymenolepis<\/jats:italic> spp. in 27 students (11.7%), hookworm in 14 (6.1%), <jats:italic>Schistosoma haematobium in<\/jats:italic> four (1.7%), <jats:italic>Enterobius vermicularis<\/jats:italic> in four (1.7%), <jats:italic>Ascaris lumbricoides<\/jats:italic> in three (1.3%), <jats:italic>Taenia<\/jats:italic> spp. in two (0.9%), and <jats:italic>Fasciola hepatica in<\/jats:italic> one (0.4%). Protozoa were observed in 17 (7.4%) students. Detection of <jats:italic>S. stercoralis<\/jats:italic> was higher using the Baermann technique versus using formol-ether (11.3 vs. 3%). Overall prevalence of <jats:italic>S. stercoralis<\/jats:italic> in the school population of 16 studied schools in the municipal area of Cubal was greater than 10%. This fact must be considered when designing deworming mass campaigns. The use of specific tests in larvae detection is needed to avoid overlooking this parasite.<\/jats:p>","DOI":"10.4269\/ajtmh.17-0159","type":"journal-article","created":{"date-parts":[[2017,8,1]],"date-time":"2017-08-01T07:00:34Z","timestamp":1501570834000},"page":"1226-1231","source":"Crossref","is-referenced-by-count":32,"title":["Prevalence
