I'm not exactly sure, but from what i've read, it only got to level 3. To get to level 4 there has to be a significant number of confirmed human to human transmission cases. And although there were a lot of cases of bird flu, not enough of them were shown to have been passed by humans so it remained at level 3. To become a pandemic level 5, there only has to be one case of human to human contact in 2 different countries. Phase 6 means there is a community level outbreak of human transmission.
