A pre- and post-intervention study in the context of a training course on infectious diseases aimed at health professionals. We designed a questionnaire with 30 questions related to the management of infectious diseases in different clinical situations. Participants had to answer the questions based on their competencies and training for these situations. We analysed the scores obtained before and after the course and the resulting progress. In addition, an open response section was provided to enable a qualitative evaluation. Two thousand one hundred and forty-eight health professionals were enrolled in the course. The questionnaire was completed before and after the course by 606 participants, mainly physicians (81.2%) and pharmacists (15.4%). The mean overall scores for the pre- and post-course questionnaires were 6.2 (SD 1.38) and 7.9 (SD 0.88), respectively (overall score increase = 1.8, SD 1.21, P  The course with a MOOC design showed a great teaching capacity in the infectious diseases area for all the clinical situations analysed, notably in the management of severe infections with higher mortality. For future editions of this training activity, the need to include other infectious diseases, especially infections in primary care, was highlighted.
