A 21-year-old foreign worker from Vietnam has become Taiwan's first patient with an indigenous case of German measles this year, the Department of Health announced Friday. The individual, who currently works in Gueishan Township in Taoyuan County, came down with a fever, rashes, a runny nose and red eyes on April 4, the DOH's Centers for Disease Control (CDC) said. The victim, who has not traveled overseas recently, was admitted to the hospital for treatment and later released. The 28 people he had contact with have not shown any suspicious symptoms so far, but the CDC said it will continue to keep track of them. The CDC reported the first imported measles cases this year on April 7 -- a 26 -year-old woman and her 15-month-old daughter in Kaohsiung County. They developed the disease after visiting relatives in Vietnam from January 26 to March 23. Taiwan has had 110 German measles cases over the past three years, of which 19 were imported (six from Vietnam) and the balance originated in Taiwan.
