Multiannual patterns of influenza A transmission in Chinese live bird market systems.
Bottom Line: However, predicting AIV epizootics and emergence in humans is confounded by insufficient empirical data on the ecology and dynamics of AIV in poultry systems.No significant seasonality was found when all subtypes were considered together.Quantitative models of control strategies must consider multiple subtypes, hosts, and source contexts to assess the effectiveness of interventions.

Mentions: Prevalence varied substantially with APMV‐1 and AIV subtypes H3, H6, and H9 being the most prevalent (Figure 1A,B). Influenza subtype H6 reached as high as 20% prevalence among all poultry species, while other subtypes, including H5, rarely reached 5%. Although quail consistently showed the highest infection rates (Figure 1C), no significant differences were observed in the mean prevalence across the three most intensively sampled host species when considering all points in the time series (Figure 1C, Table 1).
