Screening of young camels for MERS-CoV antibodies. a: A representative map of KSA showing the number of camels per province, written underneath province names. Density of colour represents the camel number per 100 km2 in each province. b and c: 362 dromedary calves below the age of 2 years were screened for anti-S1 antibodies using EUROIMMUN ELISA kits. ELISA Ratio of > 1.1 is positive, < 0.8 is negative, between 0.8 and 1.1 is equivocal. Dotted line represents the assay positive cutoff of 1.1. Seven different herds and farms were screened in Qassim (Q) province and twelve in Jouf (J) province
