A Vietnamese woman in her 30s who contracted measles in her home country, and showed signs and symptoms of the illness while sightseeing in Taiwan, is thought to have had contact with up to 215 people on the island.

According to the Taiwan Center for Disease Control, the woman arrived at Kaohsiung International Airport on May 18 with a sightseeing tour and left the country on May 22 from Taoyuan International Airport, The Liberty Times reported.

During her five-day stay, she traveled from the southwest to the north, visiting places including the Liuhe Night Market, the Fo Guang Shan Temple in Kaohsiung, Sun Moon Lake in Nantou, the Fengjia Night Market in Taichung and the Chiang Kai-shek Memorial Hall in Taipei.

It was learned that on May 21 the woman started to feel unwell with pain in her joints and a skin rash. She was admitted to a hospital where she was initially flagged as a suspected case of German measles which was later confirmed as measles after a laboratory report.

It was estimated she made contact with at least 215 people in Taiwan, but none of them on a watchlist lasting until June 12 have reported any symptoms of the disease.

Members of the public who have developed any symptoms of measles are advised to wear surgical masks, seek medical attention and tell the medical practitioner their travel history.
