MERS: Impact of comorbidity on mortality

Mens et Manus

UPDATED: 4.27.14, 2215 EST

In my last series of posts, it became quickly apparent that MERS cases who have pre-existing conditions (or “comorbidities”, such as diabetes, heart disease, etc.) are more likely to die than those who are otherwise healthy. I wanted to take a closer look at this finding by conducting some risk analyses on the data I have available to me currently. I looked at three different time frames: from March 2012 (when MERS was first documented) to present; before 3/20/2014 (the onset of the current outbreak in the Middle East); and after 3/20/2014. This is what I found:
RR_alltimeOverall, cases with comorbidities are +80% (p = .0001) more likely to die than those who are otherwise healthy.
RR_preoutbreakPrior to the current outbreak, cases with comorbidities were +70% (p = .0016) more likely to die than otherwise healthy cases – about the same as what we saw above…
