The impact of deworming on soil-transmitted helminth (STH) infections in school-aged children (SAC) measured by copromicroscopy and serology.

Copromicroscopic data is expressed as the prevalence with 95% confidence interval (95 CI) of any, low or moderate-to-high (M-H) intensity infections. The mean fecal egg count (FEC) is expressed in eggs per gram (EPG) stool. Serological response to Ascaris suum haemoglobin (AsHb) or total lung stage L3 extract (AsLungL3) is reported as mean Optical Density ratio (ODr) as measured by ELISA.
