This report reviews evidence related to airflow transmission of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and the risk associated with the use of heating, ventilation and air conditioning (HVAC) systems. A targeted literature review along with a multidisciplinary expert panel discussion were the primary approaches to examine the evidence. More robust, published, peer-reviewed evidence is needed to help clarify the potential role HVAC systems play in spreading and/or mitigating the risk of transmission of SARS-CoV-2 in order to provide more concrete evidence-based recommendations. At this time, the most substantial risk of transmission of SARS-CoV-2 is from close personal contact. As such, it remains critical to follow public health recommendations.
