A prominent authority on China's Belt and Road Initiative reveals the global risks lurking within Beijing's project of the century.

Seine riesigen Infrastrukturprojekte erstrecken sich inzwischen vom Meeresboden bis ins Weltall und von den Megastädten Afrikas bis ins ländliche Amerika. China ist dabei, die Welt zu vernetzen und die globale Ordnung neu zu gestalten. Der Kampf um die Zukunft ist eröffnet und verlangt von Amerika und seinen Verbündeten, China nicht unkontrolliert weiteres Terrain zu überlassen. Diesen Wettbewerb zu verlieren können sich die Demokratien nicht leisten. China-Experte Jonathan Hillman nimmt die Leser mit auf eine globale Reise zu den neu entstehenden Konfliktfeldern, zeigt auf, wie Chinas digitaler Fussabdruck vor Ort aussieht, und erkundet die Gefahren einer Welt, in der alle Router nach Peking führen.

Influenza A viruses of H5 and H7 subtype in poultry can circulate subclinically, and subsequently mutate from low to high pathogenicity with potentially devastating economic and welfare consequences. European Union Member States undertake surveillance of commercial and backyard poultry for early detection and control of subclinical H5 and H7 influenza A infection. This surveillance has moved towards a risk‐based sampling approach in recent years; however quantitative measures of relative risk associated with risk factors utilised in this approach are necessary for optimisation. This study describes serosurveillance for H5 and H7 influenza A in domestic and commercial poultry undertaken in the European Union from 2004 to 2010, where a random sampling and thus representative approach to serosurveillance was undertaken. Using these representative data, this study measured relative risk of seropositivity across poultry categories and spatially across the EU. Data were analysed using multivariable logistic regression. Domestic waterfowl, game birds, fattening turkeys, ratites, backyard poultry and the "other" poultry category holdings had relatively increased probability of H5 and/or H7 influenza A seropositivity, compared to laying‐hen holdings. Amongst laying‐hen holdings, free‐range rearing was associated with increased probability of H7 seropositivity. Spatial analyses detected 'hotspots' for H5 influenza A seropositivity in western France and England, and H7 influenza A seropositivity in Italy and Belgium, which may be explained by the demographics and distribution of poultry categories. Findings suggest certain poultry category holdings are at increased risk of subclinical H5 and/or H7 influenza A circulation, and free‐range rearing increases the likelihood of exposure to H7 influenza A. These findings may be used in further refining risk‐based surveillance strategies, and prioritising management strategies in influenza A outbreaks.
