A virus that can cause severe and deadly respiratory symptoms continues to spread in the Middle East, and medical personnel are among its latest victims. Saudi Arabia reported several new cases of the disease known as Middle East Respiratory Syndrome, or MERS, last week. In the United Arab Emirates, six paramedics fell ill, one of whom died. The above chart, by Ian Mackay of the Australian Infectious Diseases Research Centre at the University of Queensland, shows the tally of infections. Cases in the Kingdom of Saudia Arabia are shown in red. “I do wonder what’s happening when I have to adjust the axis scale twice in a week,” he wrote on his site, Virology Down Under. The first cases of MERS were reported in 2012.
