The unofficial, interactive world MERS map coronamap.com seems to be keeping up with MERS cases, including stats from both the World Health Organization and local health ministries.
One of its most helpful features is that it clearly distinguishes between cases where people have recovered and are no longer a threat to public health (green) and ones where people are still sick and possibly infectious (red).
Red numbers are MERS cases where people are still infected. Blue zeros represent places where people who had been infected have since recovered and therefore can't spread the virus. CoronaMap.com
The most recent World Health Organization report on MERS cites 632 total cases that have been confirmed with lab tests for the live virus. These cases have caused 193 deaths so far.
