On May 8, 2015, the Taiwan Centers for Disease Control (Taiwan CDC) confirmed a new case of rubella in a 50-year-old housewife who resides in southern Taiwan. In the evening of May 2, she developed some rashes. When her symptoms persisted the next day, she sought medical attention at a hospital. On May 4, when she returned to the hospital for further medical attention, she experienced dry throat and swollen lymph nodes in the neck. On May 7, infection with rubella was confirmed in the case. At the time of writing, the case was isolated at home for recovery. Since the case had not traveled overseas during the exposure period, Taiwan CDC determined the case to be an indigenous case. The possible source of infection is still under investigation.

To prevent further transmission of the disease, the health authorities has implemented a number of prevention measures and identified 372 contacts, including her family members, workers at the stores and markets she visited, healthcare personnel and patients that she came into contact with when she sought medical attention, to monitor and follow up until May 30. Currently, none of the contacts has developed any suspected symptoms. People who might have come into contact with the case are urged to monitor their own health for the next 21 days. When experiencing suspected symptoms such as fever and rash, please put on a facemask, seek medical assistance immediately, and voluntarily inform the physician of relevant exposure history. Pregnant women who might have come into contact with the case are urged to seek medical attention to determine the need for treatment.

Thus far this year, a total of 5 rubella cases have been confirmed in Taiwan, including two imported cases (one from China and the other from an unknown origin) and three indigenous cases. During the same period last year, a total of 4 rubella cases, which were all imported (two from China, one from Malaysia, and one from the Philippines), were confirmed. As 95% of the citizens in Taiwan have had the infection or been vaccinated against the disease and most infected individuals experience mild symptoms, the public does not need to panic over the case. However, if a pregnant woman who has no rubella antibodies becomes infected with rubella during early pregnancy, there is a chance she will pass the infection to her unborn child and a chance that the child will develop congenital rubella syndrome, resulting in fetal death, miscarriage or birth defects such as deafness, glaucoma, cataract, microcephaly, intellectual disability, heart disease and even death. Women of child-bearing age who are tested negative for rubella antibody during the pre-marital medical examination can receive a free dose of MMR vaccine when presenting the negative rubella antibody result at the local health station or a contracted hospital.

Rubella is a highly contagious disease. People who are infected with rubella are infectious from 1 week before and after the rash appears. It is transmitted through airborne droplet or close contact with the patient, but it is vaccine-preventable. If symptoms pertaining to rubella infection such as fever, fatigue, nasopharyngitis and obviously swollen lymph nodes behind the ears develop and are accompanied by generalized irregular papules, joint pain or arthritis, please put on a mask, seek immediate medical attention, and voluntarily inform the physician of relevant travel and exposure history.
