The Qinghai-Tibet Plateau is known as one of the highest endemic areas of echinococcosis. However, the dog infection rates of in the plateau regions were similar to other non-Tibetan areas with the high endemic, and most of the rates were below 40%. The infected dogs with were ubiquitous in Ganzi Prefecture of Sichuan Province and Qinghai Province where many survey data were done and available, which was much different from those in non-Ti-betan areas where the geographical distribution of dogs infected with was sporadic. The total infection rates of in dogs kept stable from 1983 to 2009 in Ganzi Prefecture of Sichuan Province and did not show much variation from 2000 to 2014 in Qinghai Province as well. Since 2006, the national comprehensive prevention and control strategy and measures against echinococcosis have been launched in China, and significant progress has been made. In the endemic Tibetan area of Sichuan, the general infection rates in dogs were 28.10%, 15.87%, 19.22%, 3.28% and 1.11% from 2009 to 2013, respectively, and the coproantigen-positive rate in Gannan Prefecture of Gansu Province and parts of Qing-hai Province also decreased. This paper reviews the literature on the characteristics of dog infections in the Qinghai-Tibetan Plateau, so as to provide useful information to support echinococcosis control and prevention there.
青藏高原被认为是棘球蚴病最高发的地区之一。然而，高原地区犬类的感染率与其他棘球蚴病高发的非藏族地区相似，且大多数感染率低于40%。在四川省甘孜州和青海省，有许多调查数据且数据可得，感染棘球蚴的犬类随处可见，这与非藏族地区不同，在非藏族地区感染棘球蚴的犬类地理分布呈散发性。1983年至2009年期间，四川省甘孜州犬类的总体感染率保持稳定，2000年至2014年期间青海省的感染率也没有太大变化。自2006年以来，中国启动了全国性的棘球蚴病综合防控策略和措施，并取得了显著进展。在四川藏族聚居的流行区，2009年至2013年期间犬类的总体感染率分别为28.10%、15.87%、19.22%、3.28%和1.11%，甘肃省甘南州和青海省部分地区的棘球蚴粪抗原阳性率也有所下降。本文综述了关于青藏高原犬类感染特征的文献，以便提供有用信息，支持该地区棘球蚴病的防控工作。
