The exercise of compulsory powers for the protection of society against the spread of infectious diseases may impose severe restrictions on individual liberty. The law should therefore enable public health officials to strike the proper balance between public health and individual rights. An overview of the infectious diseases control legislation of five European countries (Germany, Switzerland, England, Sweden and the Netherlands) shows outdated medical approaches to infectious diseases, deficiencies in substantive statutory criteria and a lack of suitable procedural protection. The law has to be modified not only to fit current epidemiological insights, but also to give full weight to evolving individual rights.
