MERS situation update, June 2018
---------------------
Highlights:
- At the end of June 2018, a total of 2229 laboratory-confirmed cases of Middle East respiratory syndrome (MERS), including 791 associated deaths (case-fatality rate: 35.5%) were reported globally; the majority of these cases were reported from Saudi Arabia (1853 cases, including 717 related deaths with a case-fatality rate of 38.7%).

- During the month of June [2018], a total of 4 laboratory-confirmed cases of MERS were reported in Saudi Arabia including 1 associated death (case-fatality rate: 25%). No healthcare associated transmission or hospital outbreak was reported during this month.

- The demographic and epidemiological characteristics of reported cases, when compared during the same corresponding period of 2013 to 2018, do not show any significant difference or change. Owing to improved infection prevention and control practices in hospitals, the number of hospital-acquired cases of MERS has dropped significantly since 2015.

- The age group 50-59 years continues to be at highest risk for acquiring infection of primary cases. The age group 30-39 years is most at risk for secondary cases. The number of deaths is higher in the age group 50-59 years for primary cases and 70-79 years for secondary cases.

More detailed graphs and tables can be found on the actual situation update document available at: http://applications.emro.who.int/docs/EMROPub_2018_EN_20337.pdf?ua=1.

[According to the May 2018 MERS-CoV update from the WHO/EMRO, there were a reported total of 2220 laboratory-confirmed cases of MERS-CoV infection reported, including 790 associated deaths (case-fatality rate: 35.6%). The majority of these cases were reported from Saudi Arabia (1844 cases, including 716 related deaths with a case-fatality rate of 38.8%) (see http://www.emro.who.int/pandemic-epidemic-diseases/mers-cov/mers-situati... contained and discussed in ProMED-mail post MERS-CoV (21): EMRO/WHO update May 2018 20180612.5852927).

While this month's update (June 2018) states that there were only 4 newly confirmed cases of MERS-CoV reported during the month, and all were reported from Saudi Arabia; the cited numbers from May to June 2018 suggest that there were 9 newly confirmed cases, all from Saudi Arabia. Unfortunately, the Saudi MOH MERS-CoV website is still undergoing revision, so I have been unable to evaluate this apparent inconsistency; perhaps there were delayed reports of MERS-CoV infections in earlier months that were added to the global tally. Information from knowledgeable sources in the region and Saudi Arabia would be gratefully appreciated.

An epidemic curve of the MERS-CoV infections reported to WHO since September 2012 can be found at the source URL for the full situation update. Looking at the tables from the report, it is clear that there has been a decrease in healthcare worker infections, with a fall to only 5 percent of cases this year [2018] in healthcare workers.
