Bird Flu Alarm

Understanding Avian Influenza

How serious is the current pandemic risk?

The H5N1 virus is now firmly entrenched in poultry in large parts of Asia.

As a result, more human cases will occur and provide the virus increasing opportunities for "reassortment", increasing the risk of the emergence of an easily transmissible human pandemic strain.

The recent spread in wild birds and poultry to new areas also allows increased opportunities for human cases to arise in an expanding geographic range, increasing the probability that a pandemic will occur.
