During the past 30 years since 1958 when malaria stratification was first made, a great change in malaria situation has occurred. The original stratification can not represent the current status of malaria distribution. Therefore, it needs to be redivided so as to provide basis for future malaria control work. Taking species of mosquito vector and malaria incidence as the main indices and making reference to the natural geographical division, the current malaria endemic area in China can be divided into four regions, i.e. (1) Western region: it is mostly a natural non-endemic area, except some limited areas with sporadic cases in Xinjiang Autonomous Region; (2) Northern region: the whole north-eastern and partial northern China belong to the areas where malaria has been basically eliminated; but sporadic occurrence still exist in most part of the northern China; (3) Central region: it is mostly a hypo-endemic area, only a small part has meso-endemicity; (4) Southern region: nearly 50% has meso-endemicity and the other 50% has hypo-endemicity. The demarcation line of natural non-endemic areas and the areas where malaria has been basically eliminated has been defined.
自1958年首次进行疟疾分层以来的过去30年里，疟疾形势发生了巨大变化。原来的分层已不能代表当前疟疾分布状况。因此，需要重新划分，以便为今后的疟疾防治工作提供依据。以蚊媒种类和疟疾发病率为主要指标，并参考自然地理区划，中国目前的疟疾流行区可分为四个区域，即：（1）西部地区：除新疆维吾尔自治区有少数散发病例的有限区域外，大多为自然非流行区；（2）北部地区：整个东北和中国部分北方地区属于疟疾已基本消除的地区；但中国北方大部分地区仍有散发病例；（3）中部地区：大多为低流行区，只有一小部分为中流行区；（4）南部地区：近50%为中流行区，另外50%为低流行区。已划定了自然非流行区和疟疾已基本消除地区的分界线。
