Respiratory viruses are difficult to characterize in the airborne environment due to their low concentration and the presence of a wide range of inhibitors. As a first step in studying airborne viruses, we optimized molecular biology methods to quantify influenza viruses and human rhinovirus. Quantitative PCR was used as an endpoint to evaluate RNA extraction techniques and reverse transcription protocols. We found that a Trizol-chloroform extraction and MultiScribe™ RT increased virus detection 10-fold compared to methods used in published field studies of airborne respiratory viruses. Virus was recovered without inhibition from samples contaminated with up to 50 μg/sample of particulate matter. The methods developed can be used in studies of airborne respiratory viruses.
