The World Health Organization's Eastern Mediterranean Regional Office (EMRO) has published an update on MERS on the Arabian peninsular for the first two months of the year, and while relatively quiet, the number of cases (n=30) is slightly higher than the same corresponding months the past two years.
While they state `No hospital outbreak was reported during the first 2 months of 2017', the Saudi MOH did report at least 2 `hospital acquired cases' in January.
- On January 10th the MOH reported a 72 y.o. female from Buraidah listed in critical condition which they described as `Secondary (Health Care Acquired)'.
- On January 27th the MOH announced a a 30 y.o. male health care worker who acquired the virus at work in Jeddah.
Presumably a single nosocomial infection doesn't meet the threshold of an `outbreak'. While it doesn't fall in this time span, earlier this week the Saudi MOH Reported 3 MERS Cases (1 Hospital Acquired).
The accompanying PDF file provides some excellent demographic and historical data on MERS-CoV.
At the end of February 2017, a total of 1916 laboratory-confirmed cases of Middle East respiratory syndrome coronavirus (MERS-CoV), including 702 deaths (case–fatality rate: 36.6%) were reported globally. Of these, Saudi Arabia reported a total of 1561 laboratory-confirmed cases, including 633 deaths (case–fatality rate: 40.6%).
During the months of January and February 2017, an increase in the number of primary cases was observed in Saudi Arabia (18 primary cases) compared to the previous 2 months (17 primary cases), as well as during the same period in 2016 (13 primary cases). In January 2017, a total of 18 laboratory-confirmed cases, including 6 deaths (case–fatality rate: 33.3%) were reported, while in February a total of 12 laboratory-confirmed cases, including 3 deaths were reported from Saudi Arabia.
No hospital outbreak was reported during the first 2 months of 2017. Despite this increase in primary cases, no significant increase in secondary cases or any difference in demographic or epidemiological characteristics of the cases were observed. The demographic and epidemiological characteristics of the cases reported in 2017 do not show any significant difference compared with cases reported during the same period from 2012 to 2016.
The age group of those aged 50–59 years continues to be the group at highest risk for acquiring infection as primary cases for both males and females. However, the females in the age group of 20–29 and 30–39 are acquiring MERS infection in higher numbers when compared to males in the same age group.
