The World Health Organization (WHO) recently came up with new guidelines that could expand population on HIV drugs by millions.
In the past, the HIV infected would start treatment when their viral load reaches a certain level of severity. Under the new guidelines, however, anyone infected with HIV is recommended to begin treatment immediately after diagnosis. This expands the number of people who are eligible for anti-retroviral drugs to about 28 million to 37 million over the world.
In addition, the guidelines recommend protective medications for those who are at substantial risk of HIV infection as studies on pre-exposure prophylaxis, or PrEP, have shown to be effective to lower the risk of becoming infected.
The WHO hopes that the revised guidelines will help halt the epidemic, but who will pay for the cost to execute those remains questionable.
