Rice paddies were identified as the best predictor of outbreak locations.

Otte et al., “Industrial Livestock Production and Global Health Risks,” Pro-Poor Livestock Policy Initiative Research Report, UN Food and Agriculture Organization, Agriculture and Consumer Protection Department, Animal Production and Health Division, June 2007. All-enclosed houses are even vulnerable to insects that spread infection. See Kyoko Sawabe et al., “Detection and Isolation of Highly Pathogenic Avian Influenza A Viruses from Blow Flies Collected in the Vicinity of an Infected Poultry Farm in Kyoto, Japan, 2004,” American Journal of Tropical Medicine and Hygiene 75, no. 2 (2006): 327-32; and Birthe Hald et al., “Flies and Campylobacter Infection of Broiler Flocks,” Emerging Infectious Diseases 10, no. 8 (Aug. 2004): 1490-92. In some cases, the fans used for ventilating enclosed houses expel contaminated particles into the outside air, where they can infect other poultry houses and farms.
