Middle East respiratory syndrome coronavirus (MERS-CoV) is an emerging virus that was
firstreportedinhumansinJune2012[1]. Todate, MERS-CoVcontinuestoinfecthumanswith
a fatality rate of ~35%. At least 27 countries have reported human infections with MERS-CoV
(https://www.who.int/emergencies/mers-cov/en/).MERS-CoVisazoonoticvirus.Likesevereacute
respiratory syndrome coronavirus (SARS-CoV), MERS-CoV is believed to have originated from
bats[2,3]. However,whereasthebat-to-humantransmissionofSARS-CoVwaslikelymediatedby
palmcivetsasintermediatehosts,humanslikelyacquiredMERS-CoVfromdromedarycamels[4–6].
Human-to-humantransmissionofMERS-CoVdoesoccur, butitislimitedmostlytohealthcare
environments [7,8]. Moreover, whereas SARS-CoV recognizes angiotensin-converting enzyme 2
(ACE2)asacellularreceptor[9,10],MERS-CoVusesdipeptidylpeptidase4(DPP4)toentertarget
cells[11,12].Currently,novaccinesorantiviraltherapeuticshavebeenapprovedfortheprevention
