In July/August 2018, a measles outbreak occurred in a reception facility for asylum seekers in Regensburg, Bavaria, Germany. A five-year-old child and an 18-year-old man from Moldova were affected. At the time of the report, 491 people were accommodated at the facility. The outbreak was limited to the two cases mentioned by the consistent use of infection control measures. Decisive factors for successfully combating this outbreak were, in particular, the close cooperation of the local public health authority (Gesundheitsamt) with the district government officials, the institution's management, and the general practitioners on site. The measures taken included the early information of all parties involved, the timely and repeated implementation of containment vaccinations, a consequent segregation of contagion and/or disease suspects and the critical consideration of each individual case in connection with the separate risk-adapted segregation of particularly vulnerable cohorts.
