Hypothesis

What is the prevalence of influenza virus (H5N1) in live bird and food markets in Thailand?

Conclusion

The study found that influenza virus (H5N1) was isolated from 12 samples in live bird and food markets, indicating a risk of contamination, especially in bird meats.

Supporting Evidence

  • 12 subtype H5N1 viruses were isolated from 930 samples tested.
  • Bird meats were the source of 9 virus-containing samples, indicating a risk for contamination.
  • Samples containing the virus were detected only during the winter season.

Takeaway

The researchers checked birds and bird meats in markets and found some had a virus that can make people sick, especially in quail meat.

Methodology

Cloacal swabs and visceral organs were sampled from various bird species in live bird and food markets over 14 months.

Limitations

The original sources of animals in the markets could not be identified due to mixed housing of birds.

Participant Demographics

Samples were collected from live chickens, ducks, pigeons, and house sparrows in 10 provinces of central Thailand.
