Indeed, despite progress in 2012, we have not been able fully to interrupt the spread of the poliovirus in Pakistan, owing primarily to obstacles affecting program implementation and management. These challenges must be addressed through stronger governance at all levels, particularly given that state authority has been badly eroded in roughly a quarter of the country, where complex factors have created distrust in the name of ethnicity, politics, and religion, resulting in a massive breakdown in law and order.
事实上，尽管2012年取得了一定的进展，但我们尚不能完全打断小儿麻痹症病毒在巴基斯坦的传播，其主要原因是计划的实施和管理遇到了各种障碍。这些障碍必须通过在各个层面上加强治理解决，特别是在约四分之一的邦级政府权威受到严重侵蚀的情况下——复杂的因素导致种族、政见、信仰间的各种不信任，使法律和秩序大规模瘫痪。
