Answer

The extraordinarily high mortality rate of avian influenza (>60% for H5N1; approximately 30% for H7N9) is worrying and reasonably accurate. There have been very few instances of seropositive individuals without clinical signs of infection. In most instances, the policy is to test exposed individuals around an outbreak (human and avian). Therefore, a large population of exposed but untested people is unlikely.
