There have been no signs of a major measles outbreak on Korea's southern resort island of Jeju after a tourist was confirmed to have been infected with the disease last week, officials said on Monday.

According to the Jeju provincial government, the results of its epidemiological investigation show that none of the 74 people who came into contact with the patient exhibited any symptoms of measles, such as fever or a red rash.

This is the first confirmed measles case on the island since 2019.

According to officials, the tourist arrived on Feb. 1 after entering Korea from Vietnam on Jan. 22. The person was found to have traveled in Vietnam for nearly two months before coming to Korea.

The tourist began showing symptoms of measles on Feb. 3 and was diagnosed with the disease three days later.

Measles is a highly contagious viral infection that causes fever, a runny nose and a rash. Once quite common, it has nearly disappeared in Korea, thanks to the widespread use of effective vaccines.

Last year, 49 people were confirmed to have been infected with measles in the country. All the patients were found to have contracted the virus either while traveling overseas or through transmission from infected travelers.
