SEOUL (Reuters) - Two South Korean hospitals are conducting experimental treatment on Middle East Respiratory Syndrome (MERS) patients, injecting them with blood plasma from recovering patients, the health ministry said on Tuesday, as four new cases were reported.

The procedure has been conducted on two consenting MERS patients in addition to existing care, the ministry's head of public health policy, Kwon Jun-wook, told a media briefing.
