Snapdate: MERS-CoV detected among asymptomatic people

A quick look  at the numbers of people without symptoms who have tested MERS-CoV positive, presumably by reverse-transcription real-time polymerase chain reaction (RT-rtPCR).

MERS-CoV detection cases are up to 571 worldwide, (575 once we get some detail of 4 UAE cases that are still AWOL) of which 117 are asymptomatic (20.4%) based on public data.  

While the number of asymptomatic detections spiked along with the recent healthcare-associated outbreak, the proportions of asymptomatic detections in a week are not that different from other periods in 2013.
