The geographic region where Pigeon Breast incidence is increasing annually is which?

Geographic patterns of disease incidence often track environmental conditions that help the organism survive and spread. Pigeon breast (pigeon fever) in horses is caused by Corynebacterium pseudotuberculosis, which can persist in soil and spread through environmental exposure and vectors like flies. The Southwest United States offers a warm, dry climate and farming practices that bring horses into contact with contaminated soil and dust, especially in late spring to summer when outbreaks are most likely. That combination makes it more likely for incidence to rise year after year there. In contrast, cooler or more humid regions and different management practices in Europe, the Northeast United States, or Africa tend to have less favorable conditions for the environmental reservoir and transmission, so they’re less likely to show the same consistent upward trend.
