Feature CONDAIR COVID-19 REPORT LOOKS AT BUILT ENVIRONMENT CONSIDERATIONS: PART 1 By Condair With the increasing spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that results in coronavirus disease 19 (COVID-19), all citizens and other building owners and occupants have an opportunity to reduce the potential for transmission through BE mediated pathways. O making process about whether to implement social distancing measures and for what duration. Increased spread of SARS-CoV-2 causing COVID-19 infections worldwide has brought increased attention and fears surrounding the prevention and control of SAR-CoV-2 from both the scientific community and the general public. More than 300 000 cases have been reported worldwide, with over 100 000 recovering. While many of the typical precautions typical for halting the spread of SARS-CoV-2 are being implemented, other less common transmission pathways should also be considered and addressed to reduce further spread. Environmentally mediated pathways for infection by other pathogens have been a concern ver the last decade, substantial research into the presence, abundance, diversity, function, and transmission of microbes in the built environment (BE) has taken place and revealed common pathogen exchange pathways and mechanisms. The synthesises this microbiology of the BE research and the known information about SARS- CoV-2 to provide actionable and achievable guidance to BE decision makers, building operators, and all indoor occupants attempting to minimise infectious disease transmission through environmentally mediated pathways. We believe this information will be useful to corporate and public administrators and individuals responsible for building operations and environmental services in their decision- The built environment can take measures to prevent further transmission of COVID-19 through the HVAC system. 42 RACA Journal I May 2020 www.hvacronline.co.za
