This is a form that makes it easier to track contacts in cases where passengers are exposed to an infectious disease during their journey. The information provided by passengers can be used by public health authorities to quickly contact passengers and their contacts in order to prevent the further spread of the disease and to protect their health. The EU PLFwebsite is a single entry point for the collection of electronic PLF forms (Passenger Locator Form), and at the same time enables easier and faster collection and exchange of data between EU Member States, making contact tracing more efficient and effective.
