SINGAPORE has reported the first confirmed case of monkeypox in Southeast Asia during this year's outbreak -- while another confirmed case has been found in South Korea.

The case in Singapore involves a British man who was in the city-state between June 15 and 17. He tested positive for monkeypox on Monday after developing skin rashes and experiencing headaches and a fever last week.

"During this period, he had largely remained in his hotel room except to visit a massage establishment and eat at three food establishments on June 16," Singapore's Ministry of Health said Tuesday.

Thirteen of the man's close contacts have been identified and contact tracing is underway, the ministry said, adding that the man is being treated at the National Centre for Infectious Diseases.

The case in South Korea involves a South Korean citizen who reported themselves to the Korea Disease Control and Prevention Agency after arriving back in the country from Germany on Wednesday. The KCDA said the South Korean -- now being treated at a facility in Seoul -- had reported having a headache before flying and had developed a fever, sore throat, fatigue and skin lesions on arrival in the country.
