Recent survey indicated that there has been an increase in the number of people taking AIDS medication. It is believed that 4 million people are able to get medication however 5 million or more across the globe are still waiting for AIDS drugs.

The recent figure released by United Nations AIDS agency can be inaccurate as these were based on incomplete data. Only 158 out of 192 member countries provided government approved data for the study.

Moreover the data given was insufficient and didn't answer many important questions for the study.

Daniel Halperin, an AIDS expert at Harvard University, said that even though some of the data are not fully clear and there are some unanswered questions, this is a dramatic improvement. It shows that all this money that has gone to treatment has made some difference.

Study also highlighted the progress made in the availability of AIDS drugs across Africa. There has been a ten-fold increase in five years in accessibility to AIDS drugs in low- and middle-income countries.

Dr. Teguest Guerma, WHO's acting AIDS director said: "We have invested a lot of funds into HIV/AIDS, but it has been a worthwhile investment because we have saved lives."
