Abstract

This case for discussion highlights some of the ethical difficulties that may arise in the use of molecular typing techniques in the control of infectious diseases. Molecular typing techniques offer evidence (stronger than regular epidemiological exploration of sources and contacts) for claims about infection routes. Such evidence will mean that public health authorities need to think about how to respond ethically to causal responsibility for contagion. In this context, questions are raised about the use of molecular typing methods for source and contact tracing in the control of infectious diseases
