Practical interim guidance to reduce the risk of infection in people exposed to avian influenza viruses

Overview

Human infection with avian influenza viruses such as A(H5N1) can cause clinical disease ranging from conjunctivitis, mild upper respiratory tract infection and gastrointestinal issues to more severe outcomes, including encephalitis, encephalopathy and death. To minimize the risk of such human infections, interventions should be implemented to reduce human exposure to birds and mammals potentially infected with avian or other animal influenza viruses. It is recommended that national authorities conduct scientific investigations and enhanced surveillance to monitor, understand the extent of, and assess the risk among occupationally exposed individuals, including those with or without clinical signs and/or symptoms, and provide appropriate clinical management.

This interim guidance will be updated as more information becomes available.
