Abstract
*<p>Cohort 1 is composed of people from 10 villages where schistosomiasis is endemic. Participants were tested for <i>S. japonicum</i> infection in 2000 (<i>T<sub>0</sub></i>), 2002 (<i>T<sub>1</sub></i>) and 2006 (<i>T<sub>2</sub></i>).</p>†<p>Cohort 2 is composed of people from 27 villages in two counties where schistosomiasis reemerged following reduction of <i>S. japonicum</i> infection prevalence below 1%. Participants were tested for <i>S. japonicum</i> infection in 2007 (<i>T<sub>0</sub></i>), 2008 (<i>T<sub>1</sub></i>) and 2010 (<i>T<sub>2</sub></i>).</p>‡<p>Infection prevalence and intensity were estimated for the source population, accounting for the stratified sampling used in enrolling cohort participants. Each individual in the cohort was assigned a weight equal to the inverse probability of being sampled.</p
