Hypothesis
Is there evidence of avian influenza infection in individuals heavily exposed to wild waterfowl?
Conclusion
The study found serologic evidence of past avian influenza infection in a duck hunter and two wildlife professionals.
Supporting Evidence
- Three individuals with extensive exposure to wild waterfowl tested positive for avian influenza A/H11.
- The study is the first to document direct transmission of avian influenza from wild birds to humans.
- Participants had significant lifetime exposure to wild ducks and geese without using protective equipment.
Takeaway
Some people who hunt ducks or work with wild birds can get a type of bird flu, even if they don't feel sick.
Methodology
The study used serologic assays, including microneutralization and hemagglutination inhibition tests, to detect antibodies against avian influenza in participants.
Limitations
The sample size was relatively small, and the study did not assess disease symptoms associated with exposure.
Participant Demographics
Participants included 39 duck hunters and 68 Iowa DNR employees, predominantly male, with an average age of 34 for hunters and 47 for DNR workers.
