Why does the current bird flu outbreak pose a risk for becoming a pandemic flu outbreak in humans?
New human flu viruses can arise from bird flu viruses that then change to a form that can infect humans and spread readily from person to person. Current bird flu outbreaks in Asia, Europe and Africa are caused by a type of flu virus called “H5N1.” Human infections and deaths due to the H5N1 virus have occurred, although the virus has at this time not developed the ability to pass easily from person to person and cause outbreaks in humans.
