UPDATE at 4:17 p.m. Friday: Saudi Arabia has confirmed 313 cases of the Middle East Respiratory Syndrome, including 92 deaths, the Ministry of Health said Friday. Of note, one of the 14 new patients caught the virus while working as a hospital receptionist.

The latest medical acronym to fear is MERS: Middle East Respiratory Syndrome. The virus has killed 83 people in the Arabian Gulf since first emerging in 2012 and now looks as if it could pose a global threat.

This week, the number of new cases rose at a rate that causes concern, the World Health Organization said in a statement.

There have been only about 350 cases detected worldwide in the past two years. But Saudi Arabia has reported more than 50 in just four days. Cases also turned up in Greece, the Philippines, Malaysia and Jordan. All of the patients were exposed to the virus in the Gulf.
