Overview
As of 11 June, 699 laboratory-confirmed cases of human infection with Middle East respiratory syndrome coronavirus (MERS-CoV) have been reported to WHO, including at least 209 deaths. Overall, 63.5% of cases reporting sex (n=677) are male and the median age is 47 years old (range 9 months-94 years old; n=695). An additional 113 cases occurring between 2012 and 2014 were reported by the Saudi Arabian Ministry of Health on 3 June 2014.
Epidemiology and Demographics
- The median age of persons with confirmed MERS-CoV infection is 47 years (range: 9 months–94 years).
- The male-to-female ratio is 1.6 to 1.0, 63.5 % of cases are reported in males.
- Twenty-three (18%) of the cases occurred in persons who were identified as health-care workers.
- Although most reported cases involved severe respiratory illness requiring hospitalization, at least 27 (21%) involved mild or no symptoms.
- Despite evidence of person-to-person transmission, the number of contacts infected by persons with confirmed infections appears to be limited. No cases have been reported in the United States, although 82 persons from 29 states have been tested for MERS-CoV infection.
Shown below is an image depicting the number of cases of Middle East respiratory syndrome coronavirus infection (58 fatal and 72 nonfatal) reported to the World Health Organization (WHO) as of September 20, 2013, by month of illness onset during 2012-2013. As of September 20, 2013, a total of 130 cases from eight countries have been reported to WHO; 58 (45%) of these cases have been fatal.
Shown below is an image depicting confirmed cases of Middle East respiratory syndrome coronavirus infection (N = 130) reported to the World Health Organization as of September 20, 2013, and history of travel from in or near the Arabian Peninsula within 14 days of illness onset during 2012-2013. All cases have been directly or indirectly linked through travel to or residence in four countries: Saudi Arabia, Qatar, Jordan, and the United Arab Emirates.
