Highly pathogenic avian Influenza virus (HPAIV) has spread in an unprecedented extent globally in recent years. Despite the large reports of cases in Asia, Europe, and North America, little is known about its circulation in South America. Here, we describe the isolation, and whole genome characterization of HPAIV obtained from sampling 26 wild bird species in Peru, representing one of the largest studies in our region following the latest HPAIV introduction in South America.

Article Synopsis
- Avian influenza virus (AIV) is a key concern for poultry and poses a pandemic risk to humans, as it evolves through migratory birds that serve as its primary hosts.
- A study in Peru involved screening 421 fecal samples from various wild bird species to identify and analyze AIV, resulting in the isolation of five low pathogenicity strains with novel genetic characteristics.
- The findings indicate that AIV in Peru could contribute to the emergence of new viral forms, emphasizing the importance of geographic factors in viral evolution.
