Lab results have confirmed the virus contracted by a 75-year- old man who came from a Middle East country to Thailand to have his heart condition treated, Public Health Minister Rajata Rajatanavin said.
The infectee came from Oman, according to deputy government spokesperson Sansern Kaewkamnerd.
The man, who is now being treated at an infectious diseases institute in central Nonthaburi province, is in stable condition, the ministry said.
Another 59 people who had contact with the infectee are also being monitored, including three of the patient's family members who traveled to Thailand with him, several from the hotel where he used to stay, hospital workers, as well as those who sat near him on the plane, the minister said.
