WHAT IS ALREADY KNOWN ABOUT THIS TOPIC?: Human immunodeficiency virus (HIV) low-level viremia (LLV) during antiretroviral therapy (ART) occurs frequently in Dehong Dai and Jingpo Autonomous Prefecture, Yunnan Province.
WHAT IS ADDED BY THIS REPORT?: Among people living with HIV who achieved virological success [viral load (VL) <1,000 copies/mL] after initiating ART in Dehong Prefecture, Southwest China, 17.6% experienced first-year LLV of 50-999 copies/mL First-year LLV emerged as an independent risk factor for subsequent viral non-suppression compared with participants maintaining first-year VL <50 copies/mL.
WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE?: Enhanced monitoring and interventions for early LLV occurrence during the first year of ART are essential, including adherence education and timely VL testing.
关于该主题已知的信息有哪些？：在云南省德宏傣族景颇族自治州，接受抗逆转录病毒治疗（ART）期间，人类免疫缺陷病毒（HIV）低水平病毒血症（LLV）频繁发生。
本报告新增了哪些内容？：在中国西南部德宏州开始接受ART治疗后实现病毒学成功[病毒载量（VL）<1000拷贝/毫升]的HIV感染者中，17.6%的人在第一年出现了50 - 999拷贝/毫升的LLV。与第一年VL维持在<50拷贝/毫升的参与者相比，第一年出现LLV成为随后病毒抑制失败的一个独立危险因素。
对公共卫生实践有何启示？：在ART治疗的第一年，加强对早期LLV发生情况的监测和干预至关重要，包括依从性教育和及时进行VL检测。
