In response to the detection of the COVID-19 virus in China in December 2019, countries in the WHO European Region have been activating national plans to ensure that health and other systems are not just prepared for but also ready to respond to importation of this new virus. This means that public health officials can rapidly respond to reports of suspect cases and identify contacts at high risk; hospitals have the necessary equipment and guidance to manage cases while protecting health-care staff and other patients from infection; and the public understands the level of risk posed by the virus and how to minimize it.
