Flu viruses are constantly changing over time. The H5N1 virus could become a pandemic strain in one of two ways: 1) it could exchange genetic material from a human flu virus and acquire the ability to easily transmit between people; or 2) it could mutate over time and adapt to human cells. This second process would likely happen over the course of several years.
