Figure 2. Time-resolved phylogenetic tree of Middle East respiratory syndrome coronavirus (MERS-CoV) genomes, Saudi Arabia, 2014, constructed by using BEAST version 1.8 (http://beast.bio.ed.ac.uk/). Upper scale bar indicates nucleotide substitutions per site. Lower scale bar indicates years in reference to sample KFMC-6 (collected May 18, 2014). Genomes sequenced in this study are indicated in bold. *Indicates major nodes with posterior probabilities >0.95. Estimated median dates for nodes A, B, C, D, and E (95% highest posterior density intervals) are A) Dec 31, 2013 (Nov 8, 2013–Feb 10, 2014), B) Jan 28, 2014 (Dec 16, 2013–Feb 27, 2014), C) Feb 15, 2014 (Jan 10, 2014–Mar 16, 2014), D) Feb 26,2014 (Jan 23, 2014–Mar 25, 2014), E) Apr 4, 2014 (Mar 9, 2014–Apr 25, 2014).
