WHAT IS ALREADY KNOWN ABOUT THIS TOPIC?: Mountain-type zoonotic visceral leishmaniasis (MT-ZVL) cases in China have increased significantly between 2015 and 2020. A total of 25 regions had re-emerged yielding 88 MT-ZVL indigenous cases, while the total number of visceral leishmaniasis cases declined.
WHAT IS ADDED BY THIS REPORT?: The transmission risk of MT-ZVL showed a trend of patchy dissemination centered on major endemic areas and medium-high risk occurrence areas of with discrete foci. Multi-point re-emergence and local outbreaks of MT-ZVL were trending in historically endemic areas.
WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE?: Risk identification and early warnings of MT-ZVL are essential in formulating precise prevention and control strategies in China. More frequent monitoring, establishing a mechanism of joint prevention and control, and highlighting health education are recommended.
关于该主题已知的信息有哪些？：2015年至2020年间，中国山区型人畜共患内脏利什曼病（MT-ZVL）病例显著增加。共有25个地区再次出现疫情，出现了88例MT-ZVL本土病例，而内脏利什曼病病例总数有所下降。
本报告补充了哪些内容？：MT-ZVL的传播风险呈现出以主要流行区和中高风险发生区为中心的点状传播趋势，存在离散病灶。MT-ZVL在历史流行地区呈多点再次出现和局部暴发趋势。
对公共卫生实践有哪些启示？：MT-ZVL的风险识别和早期预警对于中国制定精准的预防和控制策略至关重要。建议加强监测频率，建立联防联控机制，并加强健康教育。
