On April 10, 2017, the Taiwan Centers for Disease Control (Taiwan CDC) announced one confirmed measles case in a 45-year-old female who resides in northern Taiwan.　　During March 13 and 17, she visited Phuket, Thailand. On April 2, she developed symptoms, including fever, cough, runny nose, sore throat and fatigue. On April 3, she developed rash all over the body. When symptoms persisted, she respectively sought medical attention on April 4 and 5, and was hospitalized after the hospital collected specimens from her for laboratory testing and reported to the health authority as a suspected case. On April 10, infection with measles was confirmed in the case. As of now, the case has been removed from isolation and resumes her daily routines. Based on her activity and exposure history during the case’s incubation period, it is determined that the case is an imported case.

To prevent further transmission of the disease, the local health authority has implemented a number of prevention measures and identified 211 contacts, including her family members who reside in the same household, colleagues, healthcare personnel and patients that she came into contact with when she sought medical attention, to monitor and follow up until April 25, 2017.　At the moment, none of the contacts has developed suspected symptoms. During the infectious period, on April 1, the case visited Jinshan Old Street. As a result, people who visited the same place during the aforementioned time are potential contacts and are thus urged to conduct self-health management for 18 days till April 19. If suspected symptoms develop, please put on a mask immediately, seek prompt medical attention and voluntarily notify the physician of the relevant exposure history.

Thus far this year, a total of 4 measles cases have been confirmed in Taiwan and all 4 are imported cases. They respectively became infected in China, Indonesia, Europe and Thailand. So far, a cumulative total of 1,200 measles cases have been confirmed in China. During December 2016 and February 2017, measles activity in China has been on the rise even though the case number is lower than those reported during the same period in the recent 4 years. Thailand has confirmed about 1,000 measles cases, which is 5 times more than that reported during the same period last year. On the other hand, a cumulative total of 1,600 measles cases were confirmed in Indonesia last year. Several other countries have reported imported cases from Indonesia and Thailand.　Recently, measles activity in Europe has also been on the rise. Romania has been hit the hardest with approximately 4,100 cases confirmed. Germany and Italy have respectively reported 200 and 700 cases, which are both higher than that reported during the same period in the past year. Currently, Taiwan CDC has issued a travel notice of Level 1: Watch for measles to 11 countries, including China, Indonesia, Thailand, India, Kazakhstan, Romania, Italy, the Democratic Republic of the Congo, Guinea, Sierra Leone and Nigeria.　　
 

Taiwan CDC reminds that vaccination remains the best way to prevent measles. In Taiwan, the existing routine childhood vaccination schedule recommends a dose of measles, mumps, and rubella (MMR) vaccine to children 12 months of age and another dose to first graders in elementary schools. Unvaccinated infants and children, those who do not receive vaccine in a timely manner and those who have never been infected with measles are high-risk groups. Parents are urged to ensure timely vaccination of children under one year old and those who have not completed the MMR vaccine series and avoid bringing unvaccinated children to the affected areas in order to prevent infection. If travel to affected areas with children at the age of 6-12 months is unavoidable, please bring the children to the local health bureau or contracted healthcare provider for one dose of MMR vaccine. On the other hand, travelers planning to visit affected areas are advised to visit the outpatient travel clinic at contracted hospitals in the nation to determine the need for MMR vaccination 2 to 4 weeks prior to their trip.　　

Travelers returning from affected areas are advised to pay attention to their own health and the health of the infants and children residing in the same household. If symptoms pertaining to measles infection such as fever, nasopharyngitis, conjunctivitis, cough and rash develop after visiting affected areas, please voluntarily inform the quarantine officer at the airport upon arrival in Taiwan, put on a mask, seek immediate medical attention, and voluntarily inform the physician of relevant travel and exposure history. Healthcare facilities are also urged to heighten vigilance and report suspected cases according to relevant regulation in order to facilitate the implementation of subsequent prevention measures.
