TAIPEI–A 20-year-old college student was the first person to contract measles in Taiwan this year, the Center for Disease Control (CDC) said Saturday. The patient, who attends school in Taipei, came down with a rash on Feb. 18., the center said. Further investigation found that the student had received a vaccine against measles when she was one year old. However, there was no record of follow-up vaccination after she entered elementary school, CDC Deputy Director-General Shih Wen-yi said in an interview. Two days before the rash developed, the patient visited Pingsi Township for the sky lantern festival and the Shifenliao area in Taipei County, Shih said. So far, the CDC has tracked 15 people who had contact with the student, and two of them have reported feelings of discomfort, Shih said. To prevent the disease from spreading, the CDC called for passengers who took Taiwan Railway trains on Feb. 16 to and from Taipei, Pingsi and Shifenliao to conduct self-health management. Taiwan had 12 confirmed cases of indigenous and imported measles last year, CDC statistics show.
