To complement current HIV treatment methods, health agencies worldwide are improving their ways of preventing the disease. The Welsh Government is planning to introduce a "game-changing" drug on a three-year trial.

The health agency of Wales will make us of Pre-Exposure Prophylaxis (Prep) or Truvada to fight the rising cases of HIV/AIDS in the country. However, there is a significant dissenting opinion coming from experts concerning the Welsh government's plan.

The All Wales Medicines Strategy Group (AWMSG) believes that Prep should not be funded on cost-effectiveness ground. On the other hand, Welsh Health Secretary Vaughan Gething still believes the trial will be beneficial once it is finished.

"The study will help us to learn how best to provide the preventative treatment to reduce risks of HIV transmission in Wales and answer some of the questions raised by the AWMSG around incidence rates. The AWMSG is a highly regarded, independent expert group. I acknowledge their advice that there are uncertainties regarding cost-effectiveness and that they have not recommended the drug for routine use within NHS Wales at this time," BBC quoted Secretary Gething.

Wales will not be the first country to utilize Prep. Major countries like the United States have approved the use of the pill.

The pill will help people who are not infected with HIV by significantly lowering their risk of contracting the virus, according to the US Centers for Disease Control and Prevention.  When taken consistently, PrEP reduces the risk of HIV infection up to 92 percent.

Meanwhile, a global report on HIV/AIDS suggests that since the year 2000, 38.1 million people have become infected with the virus. This significant increase of cases has propelled governments and health agencies across the world to seek a definitive HIV cure while promoting prevention.
