Map showing overlap in breeding relative abundance for mallard and gadwall species. Note that the geographic distribution of gadwall breeding locations is contained almost entirely by areas where mallard breed, with similar areas of high- and low-breeding concentrations across the contiguous United States. The mallard tested positive at some of the highest rates and the gadwall was near the lowest in proportion of AIV positive tests, suggesting geographic overlap alone does not explain variations in species prevalence patterns.

Top model estimate of average predicted probability that an individual bird sampled from local watersheds during the breeding season tests positive for avian influenza virus.The probability is an average across all three years of data for all waterfowl sampled within a given watershed. Note the strong latitudinal gradient with higher probabilities of testing positive in northern latitudes and decreasing probabilities in southern latitudes.

The figure above shows the prevalence of seasonal and pH1N1 influenza vaccination coverage among women with a live birth in 29 states and New York City during the 2009-10 influenza season, based on data from the Pregnancy Risk Assessment Monitoring System (PRAMS). Seasonal and pH1N1 influenza vaccination coverage among women with live births varied among the participating states. Among the 29 states and NYC, the estimated median percentage of women with live births reporting receipt of both seasonal and pH1N1 vaccinations was 28.5% (range: 15.0%-49.9%). The median percentage of women with live births reporting receipt of seasonal or pH1N1 vaccinations was 59.3% (range: 38.9%-80.2%). Overall correlation between PRAMS data and state coverage among adult women aged 18-49 years was high (r = 0.88 for seasonal, and r = 0.80 for pH1N1); for all adults, the correlation also was high (r = 0.80 for seasonal, and r = 0.88 for pH1N1).

Relative risk of water-associated infectious diseases. Shown are relative risk distributions for different categories of water-associated infectious diseases – water-borne (A), water-carried (B), water-based (C), water-related (D), water-washed (E), and water-dispersed (F). Relative risk estimate was based on the best fit Bayesian model integrating reported outbreaks, random and spatial effects.

Statistically significant high- and low-risk areas. High risk: 95% probability that at least 0.3 infected nymphs will be collected per 1,000 m2; low risk: 95% probability that < 0.3 infected nymphs will be collected per 1,000 m2; transitional area: risk cannot be ascertained with 95% confidence (confidence interval includes 0.3); true high risk: > 0.3 infected nymphs collected in a predicted high-risk area; true low risk: < 0.3 infected nymphs collected in a predicted low-risk area; false high risk: < 0.3 infected nymphs collected in a predicted high-risk area; false low risk: > 0.3 infected nymphs collected in a predicted low-risk area.

Cumulative rainfall anomalies over Eastern Africa associated with ENSO-related teleconnections, October–December, 2005.
Negative rainfall anomalies correspond to the large-scale regional drought in Eastern Africa during October–December, 2005. Anomalies were calculated with reference to the 1995–2000 long term mean. Epicenters of chikungunya outbreaks during this period are shown by the four open black dots.
