Changes in MERS-CoV viral RNA concentrations in respiratory samples over time in 13 patients. Estimated viral loads in respiratory tract specimens collected from hospitalized MERS-CoV patients, Saudi Arabia, 1 September 2015–16 November 2017. Patient numbers with an asterisk indicate the fatality. The RNA copies of MERS-CoV in a throat swab or tracheal aspirate were estimated by means of a standard curve in the upstream of envelop (upE) real-time reverse-transcriptase polymerase chain reaction. Different color–symbol combinations denote individual patients; data points below the limit of detection are shown at different levels for clarity.
