我看见网上有人发CCTV关于美国一项新技术的运用使美国原先估计的艾滋病人数不准确的报道!
我看了CCTV的报道后就立刻找到了美国CDC的原文,发现这群人太可笑了,不去调查研究就在这里乱叫!还借以污蔑我们伟大的版主大人和徐医生!证明发现了什么更敏感的检测技术!无耻,无知,下流到如此地步!在这里,我详细的介绍这项新技术,让大家知道这群人多么可笑!
先看CDC的原文!
New technology and methodology developed by CDC show that the incidence of HIV in the United States is higher than was previously known. However, the incidence has been stable at that higher level for most of this decade. HIV incidence is the number of new HIV infections occurring during a certain time period, in this case, the year 2006.
These findings, published by in a special HIV/AIDS issue of the Journal of the American Medical Association (JAMA) that was released August 3, 2008, show that in 2006, an estimated 56,300 new HIV infections occurred – a number that is substantially higher than the previous estimate of 40,000 annual new infections. It should be noted that the new incidence estimate does not represent an actual increase in the numbers of HIV infections. Rather, a separate CDC historical trend analysis published as part of this study suggests that the annual number of new infections was never as low as 40,000 and that it has been roughly stable since the late 1990s (with estimates ranging between 55,000 and 58,500 during the three most recent time periods analyzed).
The new estimates show that gay and bi***ual men of all races and ethnicities and African American men and women are the groups most affected by HIV. Fifty three percent of all new infections in 2006 occurred in gay and bi***ual men. African Americans, while comprising 13% of the US population, accounted for 45% of the new HIV infections in 2006.
The analysis revealed some encouraging signs of progress as well significant challenges. Findings documented reductions in new infections among both injecting drug users and hetero***uals over time. Yet, the findings also indicate that HIV incidence has been steadily increasing among gay and bi***ual men since the early 1990s, confirming a trend suggested by prior data showing increases in risk behavior, ***ually transmitted diseases, and HIV diagnoses in this population throughout the past decade. The analysis also found that new infections among blacks are at a higher level than any other racial or ethnic group, though they have been roughly stable, with some fluctuations, since the early 1990s. The new estimates highlight the need for expanded HIV prevention services and should serve as a wake-up call that the US HIV/AIDS epidemic is far from over.
这就是美国疾控中心的原文!里面提到是运用一种新技术使预估美国艾滋病人数更加准确!

这个技术叫STARHS!那什么是STARHS?这里有完整解答!
What is STARHS?
The CDC-developed, breakthrough technology known as STARHS stands for Serological Testing Algorithm for Recent HIV Seroconversion. This technology allows us to know, for the first time, which HIV infections are new. CDC applied this technology in the first national surveillance system of its kind in the world to directly measure new HIV infections. CDC scientists worked for almost a decade to realize the promise of STARHS technology by combining it with an expanded HIV reporting system in the U.S. This combined approach will allow CDC to better monitor the current course of the epidemic, target prevention efforts where they are needed most, and assess the impact of prevention efforts.
注意这一句介绍;了STARHS技术!
This technology allows us to know, for the first time, which HIV infections are new?
这项技术使我们能首次知道,哪次艾滋病毒感染是最近发生的?
大家懂了么?
这项技术的优越性是能区分艾滋病毒到底是什么时候感染的!以往的技术只能认定感染了没有,而不能认定具体的感染时间!美国疾控中心通过对传统酶免法的改良,研制出新的STARHS技术,能够判定具体什么时候感染!
这项技术对于个人毫无意义!因为这项技术并不是更加敏感,而是可以知道你什么时候感染艾滋病毒的!比如你有多次高危,3年前就有,最近1个月也有,最近检测出艾滋病毒了,以前的技术无法知道你是3年前就感染的还是一个月前感染的!而STARHS技术能区分!
对于个人只要知道感染与否就行了,而对于疾控单位来说,知道什么时候感染的就具有重大意义,这有助于统计整个社会的感染情况!学过统计学的就应该知道!
这就是我的解释!想要详细了解STARHS技术,可以上美国CDC的网站!有详细介绍!中文版的可以去大学的电子图书馆去查肖遥,蒋岩的文章!详细的介绍了近期HIV阳转标准检测流程(STARHS)”! |
