Figure 7. Middle East respiratory syndrome coronavirus sequence sampling density (sequences/1 million camels) by country and year described during global genomic surveillance, 2012–2025. A) Egypt; B) Ethiopia; C) Kenya; D) Nigeria; E) Oman; F) Qatar; G) Saudi Arabia; H) United Arab Emirates. The median sampling density per country is shown by the golden-brown bar to the right. y-axes differ among countries. The Food and Agriculture Organization of the United Nations statistics database does not distinguish dromedary from Bactrian camels; data are therefore presented as contextual indicators of camel-associated surveillance coverage and should not be interpreted as species-specific estimates of dromedary reservoir coverage.
