Hypothesis

What is the geographic distribution of West Nile virus and its vertebrate host associations in the New York City region?

Conclusion

The study found that seropositive birds were widely spread throughout the New York City region, with significant local transmission documented in certain neighborhoods.

Supporting Evidence

  • 33% of the sampled birds were positive for West Nile virus-neutralizing antibodies.
  • 50% of birds sampled in Queens were seropositive for West Nile virus.
  • House Sparrows were identified as an important reservoir host for West Nile virus.

Takeaway

Scientists looked at birds in New York City to see if they had been sick from West Nile virus, and they found that many birds were infected, especially in certain areas.

Methodology

Birds were captured and tested for flavivirus-neutralizing antibodies using serological methods.

Limitations

Bird populations sampled may not be representative within each county.

Participant Demographics

Birds from 18 species in four orders were sampled, primarily in northeastern Queens and surrounding counties.
