Middle East respiratory syndrome coronavirus (MERS-CoV) is an emerging virus causing a highly fatal respiratory disease in humans. Confirmation of MERS-CoV infection and molecular study on the virus may require transportation of samples to specialized laboratories. While freezing at -80? degrees C is the gold standard method for RNA preservation, maintaining the integrity of viral RNA during transport will require additional precautions and, as a result, increase transport costs. We aimed at testing the stability of MERS-CoV RNA on spin columns of RNA extraction kit at room temperature for 16 weeks. Respiratory samples spiked with stock culture of MERS-CoV were extracted and loaded on QIAamp Viral RNA Mini Kit spin columns and preserved at room temperature. Amount of viral RNA was evaluated periodically by real-time quantitative reverse-transcription polymerase chain reaction. Minimal changes in cycle threshold values over the study period were noted, suggesting stability of viral RNA by this preservation method.
