After a fairly quiet second-half of April, for the third day in a row the Saudi MOH has announced a new, primary MERS case - this time a 40 y.o. male in Riyadh. Of particular note, all three of these cases were already listed in critical condition at the time they were announced.
Since March 8th we've seen 57 MERS cases reported by the Saudi MOH, of which 11 had already died at the time they were reported, while another 19 were listed in critical condition.
How much of this is due to delayed reporting and how much to belated diagnosis is difficult to say, but this is a trend worth watching.
