Association between Severity of MERS-CoV Infection and Incubation Period

Emerg Infect Dis. 2016 Mar;22(3):526-8. doi: 10.3201/eid2203.151437.


We analyzed data for 170 patients in South Korea who had laboratory-confirmed infection with Middle East respiratory syndrome coronavirus. A longer incubation period was associated with a reduction in the risk for death (adjusted odds ratio/1-day increase in incubation period 0.83, 95% credibility interval 0.68-1.03).

Keywords: MERS-CoV; Middle East respiratory syndrome; Middle East respiratory syndrome coronavirus; South Korea; coronavirus; illness; incubation period; infection; severity; viruses.
