Avian Influenza News and Research

RSS

Avian influenza is an infection caused by avian (bird) influenza (flu) viruses. These influenza viruses occur naturally among birds. Wild birds worldwide carry the viruses in their intestines, but usually do not get sick from them. However, avian influenza is very contagious among birds and can make some domesticated birds, including chickens, ducks, and turkeys, very sick and kill them.

How effective are prior SARS-CoV-2 infections and hybrid immunity against Omicron breakthrough infections?

Researchers performed a systematic review and meta-regression study to determine the breadth and duration of the protective immunity conferred by previous severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and hybrid immunity.
