SEOUL, South Korea's foreign ministry said Monday that there has been no confirmation of additional MERS patients among its nationals.

A South Korean man was diagnosed with MERS, or Middle East Respiratory Syndrome, over the weekend, having returned from a three-week business visit to Kuwait via the United Arab Emirates, according to the government.

Another South Korean citizen, a colleague of the 61-year-old patient, showed some symptoms of the potentially deadly virus.

He went through an inspection at a Kuwaiti hospital but tested negative, the Ministry of Foreign Affairs announced.

It added that 11 other South Koreans there who were suspected of being infected were also shown to have no problem in medical checkups.

The Kuwaiti health authorities dispatched two medical staff and one inspector to where the South Korean patient visited in a bid to track down the source of the infection, the ministry said.

It's the first reported MERS outbreak in South Korea since July 2015.
