| dc.description.abstract | Diarrhea caused by rotavirus and Giardia is a major health problem among children attending day-care centers because of inadequate personnel hygiene. Epidemiological evidence suggesting person-to-person transmission of enteric pathogens has long been recognized. This study was initiated to investigate the effectiveness of handwashing for the removal of rotavirus and Giardia from contaminated hands. The palms of participant hands were innoculated with approximately 103 Giardia cysts or 105 plaque forming units of rotavirus and the effect of washing using tap water alone, a liquid soap or a bar soap on their removal was assessed. Handwashing with liquid soap was found to be very effective in the removal of rotavirus and Giardia cysts as compared to washing with bar soap or tap water alone. The overall recovery of viruses in both bar soap and liquid soap was low (0.03-22.5%), probably due to virus inactivation by the detergent. | |
