In 2014-2015, we performed mass fecal examinations targeting a total of 2,227 schoolchildren in 3 districts (South Dagon, North Dagon, and Hlaing-thar-yar) of Yangon Region, Myanmar, using the Kato-Katz thick smear technique. The egg positive children were subjected to a mass drug administration (MDA) using a single oral dose of 400 mg albendazole. The pre-treatment egg positive rate (EPG\/person) of &lt;i&gt;A. lumbricoides&lt;\/i&gt; averaged 17.2% (15,532); it was 25.2% (21,796), 14.2% (11,816), and 12.8% (12,983) in 3 districts, respectively, and that of &lt;i&gt;T. trichiura&lt;\/i&gt; averaged 19.4% (1,074), and was 24.1% (1,040), 12.3% (852), and 21.2% (1,330) in 3 districts, respectively. Follow-up fecal examinations performed 4 months post-MDA revealed considerable decreases of &lt;i&gt;A. lumbricoides&lt;\/i&gt; prevalence (EPG\/person) to av. 8.3% (12,429), and 13.7% (17,640), 8.0% (7,797), and 4.5% (11,849) in 3 districts, respectively. However, &lt;i&gt;T. trichiura&lt;\/i&gt; did not show any recognizable decrease in the prevalence (EPG\/person) remaining at av. 18.2% (862), and 18.5% (888), 11.5% (812), and 23.3% (887) in 3 districts, respectively. The results demonstrated difficulty in short-term control of &lt;i&gt;T. trichiura&lt;\/i&gt; by MDA using albendazole and suggested necessity of either a long-term MDA (&gt;10 years) or changing the albendazole regimen into 2~3-day course (total 800 or 1,200 mg), or using an alternative drug\/drug combination.<\/jats:p>","DOI":"10.3347\/kjp.2020.58.2.195","type":"journal-article","created":{"date-parts":[[2020,4,30]],"date-time":"2020-04-30T12:52:14Z","timestamp":1588251134000},"page":"195-200","update-policy":"https:\/\/doi.org\/10.3347\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Effect
