Singapore has confirmed its first monkeypox infection and South Korea is examining two suspected cases of the virus as the disease spreads across the world.

The patient in Singapore is a 42-year-old flight attendant from the United Kingdom, marking the first instance of monkeypox in Southeast Asia during the ongoing worldwide outbreak of the illness.

The Singapore health ministry said in a statement on Monday night that the man tested positive for the virus on Monday and had often traveled in and out of the city-state in the previous week.
