HPAI/H5N1 Transmission Risks: Pathways from Poultry to Humans.

Abstract

Transmission pathways for pathogenic avian influenza, subtype H5N1 (HPAI/H5N1), are summarized. Key findings are:

To date, the occurrence of human cases of HPAI/H5N1 has been very rare

The full extent of asymptomatic or subclinical infection with HPAI/H5N1 is unknown

Several epidemiological data gaps limit our understanding of risk factors for human infection.
