Investigation protocol for potential human cases of avian influenza virus infection in the EU/EEA : 2023

This protocol sets out measures for the follow-up and management of individuals exposed to infected animals and human cases of avian influenza, and for the public health management of possible and confirmed human cases. It is based on what is known from the animal-to-human and (non-sustained) human-to-human transmission events observed previously. In this protocol we recommend a precautionary approach for managing potential, possible or confirmed cases and their contacts.
