Vietnam farmers' poultry sales during outbreaks may increase virus transmission

Small-scale poultry farmers in Vietnam tend to respond to viral outbreaks of highly pathogenic avian influenza (HPAI) by rapidly selling their birds as a way to avoid financial loss, according to a new study. As these birds are commingled with other birds in markets and trading networks, this practice may increase the likelihood of widespread disease transmission.

Generally, HA has two important functions: selection of host cell and viral entry. Upon attaching to host cells, Influenza A virus are brought into host cells via endocytosis. A lipid bilayer cargo, known as endosome, carries influenza A virus from cell membrane into cytoplasm of host cell. Although the environment inside endosome is acidic, influenza A virus remains alive.
