The Swiss School of Public Health (SSPH+) assembles the inter-university faculty of public health sciences affiliated with fourteen Swiss universities of the SSPH+ Foundation. SSPH+ is the national coordinating body for the promotion of postgraduate university education and research in the fields of public health based on the vision that public health is a scientific and professional field, shaped by a broad range of disciplines. In a small country like Switzerland, no single institution has the critical mass needed to cover all public health relevant areas. The “virtual inter-university faculty” provides a promising base from which to strengthen public health by assembling over 270 professors in public health sciences from all over Switzerland. SSPH+ initiates and supports a range of cross-university academic activities that would not be supported by a single university.
