Health officials in Thailand on Sunday confirmed the country’s second case Middle East respiratory syndrome (MERS).

The patient, a 71-year-old Omani national, arrived in Bangkok on Friday to seek treatment for a persistent fever and cough. He had previously sought treatment in his home country but opted to travel to Thailand, a popular destination for patients from the Middle East, when his condition didn’t improve, health ministry officials said.

Ministry officials said they have quarantined, and are monitoring, 37 people who had close contact with the man, including family members who traveled with him, as well as a taxi driver, passengers who sat near him, flight attendants and hospital personnel.
