Evaluating COVID-19 in Air
SARS-CoV-2 that causes COVID-19 is a new virus with many unanswered questions. However, scientific professionals
can look to previous investigations of coronaviruses such as SARS-CoV and the general principles of evaluating biological
contaminants. SARS-CoV investigations focused on identifying environmental contamination in infected areas and the potential for transmission to adjacent areas. Sampling approaches included swab sampling of surfaces and air sampling followed by DNA-based Polymerase Chain Reaction (PCR) analysis.1
Listed in our COVID-19 Facts & Sampling Solutions Bulletin are some air sampling options for viruses and important details on sampler selection. Consider that viruses are not routinely sampled in indoor air quality investigations because they are typically found in very low levels that are difficult to detect. Viruses are challenging to culture because they require a host cell to grow. SKC recommends that you seek guidance from a qualified environmental microbiology laboratory with expertise in viruses before performing any air sampling or studies.
