Microbial exposure and health assessments in sanitation technologies and systems

Abstract

High: An exposure pathway associated with a technology results in a diarrhoea infection or helminthiasis risk ratio (or odd ratio) of > 1 or infection risk of > 1 in 10,000 per person per year. Risk management.This part of the health risk assessment framework relates to different practices that will reduce exposure or further reduce the inputs of organisms to a technology and thereby reduce the risks further.
