Following the success of the first WHO Observership in 2013, the number of participants was doubled from 5 to 10, but 2 were sadly unable to attend. The organizers benefited from feedback from the first visit to further improve the experience. From September 30 – October 2 the second ESCMID-WHO Observership took place at the Division of Communicable Diseases, Health Security and Environment (DCE) of the WHO Regional Office for Europe in Copenhagen, Denmark. During the 3 day Observership, 8 participants were introduced to WHO activities and programmes via presentations, case studies, a tour of UN city and further, more in-depth meetings with staff working on programme for which the Observers had indicated their specific interest. For a list of Observers, please see below. The Observers received a broad overview of the scope of WHO, and had the opportunity to talk to many different WHO staff working in a variety of public health fields. As they did last year, the Observers prepared presentations on their impressions during the visit as well as opportunities for collaboration with WHO, which led to a fruitful discussion.
