1背景麻疹病毒分子特征分析是麻疹监测的重要组成部分,有助于加强麻疹监测和流行病学调查,以分析辨别麻疹病毒的来源和追踪病毒的传播途径。对麻疹病毒基因型的变化进行长期监测为一些国家或地区已经阻断麻疹传播提供了证据。同时也是评价控制和消除麻疹计划效果的有效工具。世
Background The molecular characterization of measles virus, an important part of measles surveillance, helps to strengthen the surveillance and epidemiological survey of measles to analyze the sources of measles virus and track its transmission. Long-term monitoring of changes in the genotype of measles has provided evidence that some countries have blocked the spread of measles. It is also an effective tool to evaluate the effects of control and elimination of measles programs. world
