艾滋病病毒(Human immunodeficiency virus,HIV)侵入人体后不断复制,造成CD+4T淋巴细胞(简称CD4细胞)数量持续减少,产生细胞免疫缺陷,从而增加各种机会性感染。新余市通过对CD4细胞计数统计分析,评价该地区新发现HIV感染者的机体免疫功能情况,判断疾病进程,以便及时开展治疗工作。1对象与方法1.1对象2008-2012年,新余市新发现的、并进行 Human immunodeficiency virus (HIV) continuously invades the human body, resulting in a continuous decrease in the number of CD + 4T lymphocytes (CD4 cells for short), resulting in cellular immune deficiency, thereby increasing various opportunistic infections. Xinyu City, through the statistical analysis of CD4 cell count, evaluate the immune function of newly discovered HIV-infected persons in the area and judge the progress of the disease in order to carry out timely treatment. 1 objects and methods 1.1 object 2008-2012, Xinyu City, newly discovered, and carried out
