The new Middle Eastern concern 來自中東的新憂慮
As of early May 2014, about 500 confirmed human cases of MERS-CoV infection have been notified to World Health Organization (WHO). These reports came from countries in Europe, Asia, Africa and North America, as reflected by the red star symbols on the inset map at right upper corner.
Nonetheless, MERS-CoV remains concentrated in Saudi Arabia in Middle East. The chart at the lower right corner shows the epidemic curve between April 2013 and early May 2014 in Saudi Arabia. In April 2014, the total number of reported cases rose above 160, a figure much higher than that in any preceding month.
Between January and early May 2014, 6 regions in Saudi Arabia have reported confirmed MERS-CoV cases, with the highest number in Makkah and Riyadh, as shown in the map. A proportion of confirmed cases had history of animal exposure (e.g. camel) in Ash Sharqiyah and Riyadh, while more than half in Tabuk and Al Madinah had contracted the virus through human contact. As shown in the chart, the proportion of reported cases from human-to-human transmission has increased, many of which occurring in health care settings, which is a cause for concern.
Data for the map were extracted from WHO and Ministry of Health, Kingdom of Saudi Arabia.
