ULAN BATOR, Feb. 24 (Xinhua) -- Mongolia has confirmed another imported case of measles, bringing the total to four, local media reported on Monday, citing the country's National Center for Communicable Diseases (NCCD).

According to the NCCD, all confirmed cases involve Mongolian citizens who recently returned from Vietnam. The center has urged those who have traveled to Vietnam to get tested and vaccinated immediately.

Health authorities are also advising the public to follow key preventive measures, including wearing masks in public, practicing regular handwashing, and ensuring measles vaccination at least 14 days before traveling to affected areas.
