As a major global public health issue, HIVvirus makes the infected individuals extremely vulnerable by destroying theirbody’s immune system andfinally causes acquired immunodeficiency syndrome(AIDS) with high mortality rate (Lozano et al., 2012).Since the beginning of the HIV epidemic, there are more than 70 million individuals having been infected and about half of them have died due to HIV(Stein et al., 2016).The reported HIV new cases alsocontinueto growin recent data.By the end of 2015, a total of approximately 36.7million[34.0million -- 39.8million]individualswerebeing infected by HIV throughout the world, which was 2.7 million higher than the numbers estimated in 2012(World Health Organization, 2012).Around 2.7 million individuals became HIV-positive virus carriersin 2010(World Health Organization, 2012). In 2015, 1.1 million [0.94 million -- 1.3 million]individuals died from HIVand AIDS worldwide.In Australia,the annual number of new people being diagnosedwith HIV increased by 10% in 2012 comparing to the numbers only one year ago(Australian Government Department of Health, 2014).
之后的主题body部分开始分析问题,我们节选了部分内容来展示我们范文essay的遣词造句和起承转合,这个部分对逻辑要求很高,除了逻辑思维之外,还要求作者有相关的理论知识的储备和做research的能力,也同样对分析筛选信息的能力有要求,作者需要深入浅出的分析问题,让读者可以看懂并理解。
