Clinical signs in dromedary camels inoculated with Middle East respiratory syndrome coronavirus (MERS-CoV). A) Nasal discharge observed in camel 3; each of 3 inoculated camels had nasal discharge during the first 2 weeks of the experiment. B) Rectal temperatures are indicated for each camel by lines with geometric shapes. Horizontal lines indicate the normal temperature range observed among these dromedary camels as calculated by mean ± 3×, the before inoculation.
