- A new study revealed that the anti-retroviral (ARV) treatment is failing among one third of sub-Saharan HIV/AIDS patients.
Conducted by the Boston University School of Public Health in United States, the study, carried out in 13 sub-Saharan countries, was published by the Public Libray of Science.
It showed that sub-Saharan patients on ARV medication die or discontinue treatment within two years of starting it, with only 61% of all patients still receiving medication.
The study discovered that that many patients were either too late to use ARV or impossible for them to travel to distant clinics for treatment. Some patients discontinued treatment when they were charged to pay for the services.
It was proven that some patients lately used the ARV drugs and died within few months after starting the treatment.
The retention rates for country's programmes also vary. While one South African programme recorded 85% retention after two years of treatment that of Uganda recorded 46% retention during the same period.
However, researchers took note of the varying rates of success, which depended on countries different anti-retroviral programmes.

Studies have shown low infection rates in West Africa. It is believed that Nigeria's AIDS population is bigger than any other African country, except South Africa.
