COVID-19: Complexities in understanding transmission pathways through sanitary systems in high-rise buildings.

Abstract

The article published recently in the Lancet Global Health, COVID-19: mitigating the transmission via wastewater plumbing systems [1] is a synthesis of 17 years of study into the spread of disease as a result of defects in the wastewater plumbing system (sanitary system) within buildings, however it the issues associated with this mode of transmission are more appropriately attributed to tall (high-rise) or complex buildings [2].
