這是我們在2017年為澳洲墨爾本市維多利亞大學的客戶創作的一篇醫學essay，以Use of PrEP in HIV prevention
What arehuman immunodeficiency virus (HIV) and its global impacts?為題來分析，開篇introduction介紹研究問題的背景information，我們節選了這一個部分分享給大家。
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).
之後的主題body部分開始分析問題，我們節選了部分內容來展示我們範文essay的遣詞造句和起承轉合，這個部分對邏輯要求很高，除了邏輯思維之外，還要求作者有相關的理論知識的儲備和做research的能力，也同樣對分析篩選信息的能力有要求，作者需要深入淺出的分析問題，讓讀者可以看懂並理解。
Unsafe sex behaviour without a condom, sharing needles no matter for what purpose and newborns getting from their mothers (in some cases during childbirth or breastfeeding) are three common ways by which the HIV is spread.

Within the first 14 to 28days after being infectedinitially, some individuals may have no symptoms at all orexperience a flu-likesymptoms including night sweats, fatigue,chills ormuscle aches.However, if have had unprotected sex before,the only way to know for sure of diagnosed HIV is to see the doctor and get tested.
There is no cure for HIV infection so far. Fortunately, numbers of HIV prevention methods are availablewith promising results for slowing the spread of the HIV, such askeeping the safe sexual activities (like using condoms) and taking antiretroviral drugs. The antiretroviral drugs are introduced to help control the transmission of HIV virus so that the lives of HIV-infected and HIV-uninfected .
